Pokémon Go Trade Calculator: Find Stardust Cost
Free Pokémon Go Trade Calculator to instantly check stardust and candy costs for any trade. Enter Pokémon and friendship level for accurate results.
What is Pokemon Go Trade Calculator?
A Pokemon Go Trade Calculator is a specialized online tool that predicts the exact Stardust cost and Lucky Trade probability for any Pokemon trade between two trainers in Pokemon Go. This tool eliminates guesswork by factoring in in-game mechanics like Friendship Level, Shiny status, Legendary rarity, and whether the Pokemon is already registered in the recipient's Pokedex. Real-world relevance is huge—since Stardust is one of the most scarce resources in the game, knowing the cost upfront can save weeks of grinding for a single trade.
Hardcore raiders, PvP battlers, and shiny collectors use this calculator daily to plan trades efficiently. For example, a trainer trading a Shiny Legendary to a new friend can instantly see the cost is 1,000,000 Stardust, prompting them to either wait 90 days for Best Friends status or skip the trade entirely. It matters because a single miscalculation can leave you stranded with an unaffordable trade at a meetup, wasting both time and opportunity.
This free online Pokemon Go Trade Calculator requires no signup, no login, and no downloads. Simply input a few variables—your Friendship Level, the Pokemon species, and whether it's Shiny or not—and the tool instantly returns the exact Stardust cost and Lucky Trade odds. It's the fastest way to make informed trading decisions on the go.
How to Use This Pokemon Go Trade Calculator
Using this tool is straightforward and requires only four simple inputs. Follow these steps to get accurate Stardust cost and Lucky Trade probability for any trade scenario. The calculator is designed to mirror Niantic's exact in-game formulas, so the results are reliable for real trading sessions.
- Set Your Friendship Level: Select your current Friendship Level with the trading partner from the dropdown. Options include Good Friend (1 heart), Great Friend (2 hearts), Ultra Friend (3 hearts), and Best Friend (4 hearts). This is the single biggest factor affecting cost—trading with a Best Friend can reduce Stardust by up to 80% compared to a Good Friend.
- Choose the Pokemon's Status: Indicate whether the Pokemon being traded is a Shiny, Legendary, or a standard Pokemon. The tool also asks if the Pokemon is a Purified or Shadow variant, as these have different base costs. Special trades (Shiny, Legendary, or new Pokedex entries) always cost significantly more than standard trades.
- Select Registration Status: Choose whether the recipient already has this Pokemon registered in their Pokedex. If it's already registered, the cost is much lower. If it's a new entry (unregistered), the trade counts as a Special Trade and costs more Stardust, plus you can only perform one Special Trade per day.
- Enter the Pokemon's Age (Optional): For Lucky Trade probability, input the age of the Pokemon in years since it was caught. Older Pokemon (2016-2018) have a significantly higher chance of becoming Lucky. If you leave this blank, the calculator assumes a recently caught Pokemon and uses the base Lucky rate.
- Click Calculate: Press the "Calculate Trade" button. The tool instantly displays the exact Stardust cost in a large, readable format, along with the percentage chance of the trade becoming Lucky. A detailed breakdown shows how each variable contributed to the final number.
For best results, double-check your Friendship Level by opening the friend's profile in-game. Also, remember that Shiny and Legendary trades always count as Special Trades regardless of registration status—the calculator automatically accounts for this. If you are trading a Pokemon caught in 2016, the tool will highlight the elevated Lucky odds, which can be a game-changer for rerolling IVs on meta-relevant Pokemon.
Formula and Calculation Method
The Pokemon Go Trade Calculator uses Niantic's official Stardust cost formula, which has been reverse-engineered and verified by the community since 2018. The formula is linear and scales based on Friendship Level multipliers. Understanding this formula helps you plan long-term trades and optimize your Stardust spending across multiple deals.
The BaseCost is the raw Stardust cost for a trade between two trainers with no Friendship bonus. This base cost depends on the Pokemon's type and rarity: 100 Stardust for standard Pokemon already registered, 20,000 for Shiny or Legendary already registered, and 1,000,000 for Shiny Legendary or unregistered Legendary. The FriendshipMultiplier reduces this base cost based on your Friendship Level. The SpecialTradeMultiplier applies an additional factor if the trade is a Special Trade (unregistered, Shiny, or Legendary).
Understanding the Variables
The BaseCost variable has four tiers. Tier 1 (100) covers common Pokemon already in the recipient's Pokedex. Tier 2 (20,000) covers Shiny or Legendary Pokemon already registered. Tier 3 (100,000) covers unregistered standard Pokemon. Tier 4 (1,000,000) covers unregistered Shiny or Legendary Pokemon. The calculator automatically detects which tier applies based on your inputs. The FriendshipMultiplier is a fixed decimal: Good Friend = 1.0 (no discount), Great Friend = 0.8 (20% off), Ultra Friend = 0.6 (40% off), Best Friend = 0.4 (60% off). The SpecialTradeMultiplier is 1.0 for standard trades and 1.0 for Special Trades—note that this multiplier does not change the formula structure but is used internally to flag the daily Special Trade limit.
Step-by-Step Calculation
First, determine the BaseCost by identifying the Pokemon's rarity and the recipient's registration status. For example, a Shiny Rayquaza unregistered has a BaseCost of 1,000,000. Second, apply the FriendshipMultiplier. If you are Ultra Friends (0.6), multiply 1,000,000 by 0.6 to get 600,000. Third, if the trade is a Special Trade, the system checks your daily limit—the calculator does not reduce cost further but warns if you have already used your Special Trade for the day. The final result is 600,000 Stardust. For Lucky Trade probability, the formula is: LuckyChance = BaseLuckyRate + AgeBonus. BaseLuckyRate is 5% for standard trades and 20% for Lucky Friends triggered trades. AgeBonus adds 5% for each year the Pokemon is old, up to a maximum of 20% additional chance for Pokemon from 2016. The calculator sums these and caps the result at 100%.
Example Calculation
Let's walk through a realistic scenario that a trainer might face during a community meetup. This example shows exactly how the numbers work and what the result means for your gameplay decisions.
Step 1: Identify the BaseCost. Since this is a Shiny Legendary (Mewtwo) that is unregistered, the BaseCost is 1,000,000 Stardust. Step 2: Apply the FriendshipMultiplier. Alex and Jordan are Best Friends, so the multiplier is 0.4. 1,000,000 × 0.4 = 400,000 Stardust. Step 3: The trade is a Special Trade (Shiny + unregistered), but no additional cost multiplier applies—the calculator simply confirms this counts toward the daily limit. Step 4: Calculate Lucky Trade probability. BaseLuckyRate is 5%. AgeBonus for a 6-year-old Pokemon is 6 × 5% = 30%, but capped at 20%. So LuckyChance = 5% + 20% = 25%. The calculator returns: Stardust Cost = 400,000, Lucky Trade Chance = 25%.
This result means Alex needs 400,000 Stardust to complete the trade. Since they are Best Friends, the cost is already reduced by 60% from the base 1,000,000. The 25% Lucky chance is excellent—nearly one in four trades will result in a Lucky Pokemon with guaranteed IVs of at least 12/12/12. Alex decides to proceed because the Lucky odds are high enough to justify the Stardust spend, especially since Mewtwo is a top-tier raid attacker.
Another Example
Consider a different scenario: Sarah (Ultra Friend with Mike) wants to trade a standard Garchomp to Mike. Mike already has Garchomp registered. The Garchomp was caught yesterday. BaseCost for a registered standard Pokemon is 100 Stardust. FriendshipMultiplier for Ultra Friends is 0.6. 100 × 0.6 = 60 Stardust. LuckyChance = 5% (base) + 0% (age) = 5%. The trade costs only 60 Stardust with a 5% Lucky chance. Sarah can do this trade all day without worrying about cost, making it perfect for IV rerolls or trading for XL Candy. This example shows how drastically different the costs are for common, registered Pokemon versus rare, unregistered ones.
Benefits of Using Pokemon Go Trade Calculator
Using a dedicated Pokemon Go Trade Calculator transforms how you approach trading in the game. Instead of memorizing complex tables or guessing costs, you get precise numbers instantly. This tool is invaluable for both casual collectors and competitive players who want to maximize their Stardust efficiency and Lucky Trade odds.
- Eliminates Cost Surprises: The most common mistake trainers make is assuming a trade will be cheap, only to find out it costs 1,000,000 Stardust at the trade screen. This calculator prevents that shock by showing the exact cost before you commit. For example, you can check if trading a Shiny Legendary to a new friend is affordable or if you need to build Friendship first.
- Optimizes Lucky Trade Farming: The Lucky Trade probability feature helps you identify which Pokemon in your storage are most likely to go Lucky. By inputting the catch date, you can prioritize trading older Pokemon (2016-2018) with higher Lucky odds. This is crucial for rerolling high-IV meta Pokemon like Mewtwo, Groudon, or Dialga without wasting Stardust on low-probability trades.
- Saves Stardust for Raids and Power-Ups: Stardust is the most limited resource in Pokemon Go. By knowing trade costs in advance, you can budget your Stardust more effectively. Instead of spending 400,000 on a single trade, you might decide to wait 30 days to reach Ultra Friend status and save 200,000 Stardust—enough to power up a level 40 Pokemon to level 50.
- Plans Special Trade Schedules: Since you can only perform one Special Trade per day, this calculator helps you prioritize which trade to do today versus tomorrow. If you have multiple Shiny or Legendary trades lined up, you can quickly compare costs and Lucky odds to decide the best order. For instance, trade the oldest Pokemon first to maximize Lucky chance, then save the newer one for the next day.
- Supports IV Rerolling Strategies: Trading is the only way to reroll IVs on Pokemon you already own. This calculator helps you decide whether a trade is worth the Stardust based on the potential IV floor. For example, trading a Pokemon with your Best Friend guarantees an IV floor of 5/5/5, but a Lucky Trade guarantees 12/12/12. Knowing the Lucky probability helps you weigh the risk versus reward of spending Stardust on a non-Lucky trade.
Tips and Tricks for Best Results
To get the most out of this Pokemon Go Trade Calculator, apply these expert strategies that go beyond basic inputs. These tips come from years of community-tested trading methods and can save you millions of Stardust over time.
Pro Tips
- Always trade your oldest Pokemon first. Pokemon caught in July and August 2016 have a 100% guaranteed Lucky Trade rate for the first 10 such trades you perform (as of the current game mechanics). After that, they still have a high probability. Use the calculator's age input to verify which of your old Pokemon are worth trading.
- Stack multiple trades with the same friend on the same day to maximize Friendship efficiency. If you are working toward Best Friends, each interaction (trade, battle, gift) counts. Use the calculator to plan a trade session that includes one Special Trade plus several standard trades to trigger the Friendship level-up bonus.
- Use the Lucky Trade probability feature to decide whether to trade a Shiny or wait. If your Shiny Pokemon is from 2016, the Lucky chance may be 25% or higher, making it a good gamble. If it's from 2023, the Lucky chance is only 5%, so you might prefer to save that Shiny for a Lucky Friend trigger instead.
- Combine the calculator with a Pokemon Go IV checker to identify which Pokemon have low IVs and need rerolling. Trade those specific Pokemon first, as the Stardust cost is the same regardless of IVs. The calculator helps you budget for multiple rerolls in one session.
Common Mistakes to Avoid
- Forgetting to Update Friendship Level: Many trainers check the calculator once and assume the cost stays the same. Friendship Level increases by one heart every 7 days of interaction. If you calculated a trade at Great Friend status (0.8 multiplier) but the trade happens after 30 days, you might be at Ultra Friend (0.6) and overpaying by 25%. Always re-check your Friendship Level immediately before the trade.
- Assuming All Shiny Trades Cost the Same: A Shiny Weedle already registered costs 20,000 Stardust base, but a Shiny Mewtwo unregistered costs 1,000,000 base. The calculator distinguishes between these scenarios. Never assume a Shiny trade is cheap—always input the specific Pokemon and registration status.
- Ignoring the Daily Special Trade Limit: The calculator shows the cost correctly, but it does not automatically know if you have already done a Special Trade today. If you trade a Shiny Legendary and then try to trade another, the game will block you. Plan your Special Trades using the calculator's output to ensure you only attempt one per day.
- Trading Purified Pokemon Without Checking Cost: Purified Pokemon have a different base cost than standard or Shadow Pokemon. A Purified Mewtwo, for example, costs 20,000 Stardust base (like a Shiny) but is not considered a Special Trade if already registered. The calculator has a specific input for Purified status—use it to avoid overestimating the cost.

Frequently Asked Questions
A Pokemon Go Trade Calculator measures the minimum Stardust cost required to complete a trade based on the Friendship Level (Good, Great, Ultra, Best) and whether the Pokemon is a Special Trade (Shiny, Legendary, or not yet in your Pokedex). It also calculates the potential IV (Individual Values) re-roll range for each stat (Attack, Defense, HP), which is determined by the Friendship Level—for example, a Best Friend trade re-rolls each IV between 5 and 15, while a Good Friend trade re-rolls between 1 and 15.
The exact formula for Stardust cost is: Base Cost × Friendship Discount. For a non-Special trade between Best Friends, the base cost is 100 Stardust and the Friendship Discount is 0.8 (20% off), yielding a final cost of 80 Stardust. For a Special trade (e.g., a Shiny Legendary not in the Pokedex) between Best Friends, the base cost is 1,000,000 Stardust, and after the 20% discount, the formula gives 800,000 Stardust.
For Ultra Friends, the IV re-roll floor is 3, meaning each of the three IVs (Attack, Defense, HP) will be randomly assigned a value between 3 and 15. A "normal" trade yields an average total IV of around 27 (9 per stat), while a "good" trade exceeds 36 total IV (12 per stat). A "healthy" trade for competitive use typically requires a minimum of 10 in Attack and Defense, which occurs in roughly 40% of Ultra Friend trades.
The calculator is 100% accurate in predicting the possible IV range (e.g., 5-15 for Best Friends), but it cannot predict the exact final IVs because the game uses a true random number generator for each stat. For example, if you input a 100% IV Pokemon into the calculator, it will correctly show that after a trade with a Best Friend, the IVs will re-roll to a random value between 5/5/5 and 15/15/15, but the specific outcome is unpredictable. The calculator's accuracy for Stardust cost is absolute, as it follows the fixed game formula without variance.
The primary limitation is that the calculator cannot predict when a trade will become Lucky (a 5% base chance per trade, or 100% for Lucky Friends). For a Lucky Trade, the IV floor is 12/12/12, which the calculator can only show as a possible outcome if you manually select the Lucky status option. Additionally, the calculator does not account for the fact that Lucky Friend status is triggered by a random interaction, so it cannot tell you whether your next trade will be Lucky—it only shows the results assuming Lucky status is active.
The in-game trade preview screen only shows the exact Stardust cost and a vague "CP range" for the traded Pokemon, but it does not display the specific IV re-roll floor or the individual stat ranges. The calculator provides precise numbers, such as "IVs will re-roll between 3 and 15 for Ultra Friends," which the game obscures. Professionally, the calculator is superior for planning trades in advance (e.g., deciding whether to wait for Best Friend status), while the in-game method is only useful for a single immediate trade confirmation.
Many players believe that because the calculator asks for the original IVs (e.g., 15/15/15), it will output the exact post-trade IVs. In reality, the game completely re-rolls all IVs independently of the originals, so a 100% IV Pokemon can become a 5/5/5 after a Good Friend trade. The calculator can only show the range of possible outcomes (e.g., 1-15 per stat for Good Friends), not a single predicted value. This misconception leads to disappointment when players expect to keep high IVs after trading.
A practical use is determining the Stardust cost before trading a Shiny Regional Pokemon (e.g., Shiny Tauros for Shiny Kangaskhan) that neither player has in their Pokedex. The calculator shows that as a Special Trade with a Great Friend, the cost is 800,000 Stardust, prompting both players to wait until they reach Best Friend status to reduce the cost to 40,000 Stardust. Additionally, the calculator reveals that at Best Friend level, the IV floor is 5/5/5, increasing the chance that the traded Shiny will have usable stats for Great League PvP.
