What is Genshin Impact Welkin Calculator?

A Genshin Impact Welkin Calculator is a specialized digital tool designed to compute the total amount of Primogems and Intertwined Fates a player receives after purchasing the Blessing of the Welkin Moon pass in Genshin Impact. This monthly subscription grants 90 Primogems per day for 30 days, plus an initial batch of 300 Genesis Crystals, which can be converted into additional Primogems. The calculator takes your current Primogem balance, daily commission earnings, and remaining Welkin days to project your total resources over a specific time horizon, helping you plan for upcoming character banners.

Players who invest in the Welkin Moon pass often struggle to track exactly how many Primogems they will accumulate before a desired 5-star character like Furina, Neuvillette, or Arlecchino leaves the limited-time banner. This tool eliminates guesswork by providing a precise count that accounts for daily commissions, Spiral Abyss resets, and event rewards alongside the Welkin income. It is especially valuable for free-to-play players who occasionally purchase the Welkin Moon and need to know if they can reach the 90-pull hard pity or the 180-pull guarantee before a banner expires.

Our free online Genshin Impact Welkin Calculator requires no signup, no downloads, and no personal data. You simply input a few key numbers, and the tool instantly generates a detailed breakdown of your projected Primogem income, including a day-by-day accumulation schedule. This makes it an indispensable resource for the Genshin Impact community, whether you are a casual player saving for a favorite character or a meta-focused player planning for constellations and signature weapons.

How to Use This Genshin Impact Welkin Calculator

Using our Genshin Impact Welkin Calculator is straightforward and takes less than one minute. The interface is designed for clarity, with labeled input fields and real-time results that update as you adjust any value. Follow these five simple steps to get your personalized Primogem projection.

  1. Enter Your Current Primogem Count: Open your Genshin Impact game menu and navigate to the Paimon menu to see your current Primogem balance displayed at the top of the screen. Type this exact number into the "Current Primogems" field. Even if you have zero Primogems, entering 0 is perfectly fine—the calculator will still work accurately.
  2. Set Your Remaining Welkin Days: Check how many days are left on your Blessing of the Welkin Moon subscription. You can find this by opening the Battle Pass menu and looking at the Welkin Moon icon in the top-right corner. Enter this number into the "Remaining Welkin Days" field. If you have not yet purchased the Welkin Moon, you can enter 0, and the calculator will ignore the daily Welkin income.
  3. Input Your Daily Commission Target: Decide how many daily commissions you plan to complete each day. The standard is 4 commissions per day, which grants 60 Primogems. If you skip commissions some days, adjust this number downward. For players who always finish commissions, leave it at 4. The calculator multiplies this by the number of days in your projection period.
  4. Choose Your Projection Period: Select the number of days you want to project forward—common choices are 7 days (one week), 14 days (two weeks), 30 days (one full Welkin cycle), or until the next banner ends. If you know the exact banner end date, calculate the remaining days and enter that number. The tool will sum all income sources over this period.
  5. Optional: Add Spiral Abyss and Events: If you plan to complete Spiral Abyss floors 9-12 (up to 600 Primogems every two weeks) or expect event rewards (typically 420-1,680 Primogems per patch), you can enter those estimates. The calculator adds these one-time rewards to your total. Click "Calculate" to see your final projected Primogem count, number of Intertwined Fates, and whether you will reach soft pity, hard pity, or the guarantee.

For best accuracy, update your inputs every few days as your Primogem balance changes and as you complete more events. The calculator also shows a "Days to Pity" metric, telling you exactly how many days remain before you can perform a 10-pull or reach the 75-pull soft pity threshold.

Formula and Calculation Method

The Genshin Impact Welkin Calculator uses a simple additive formula that combines multiple income streams over a defined time period. The core logic is based on the fixed daily rewards from the Welkin Moon pass, the variable daily commission income, and any one-time bonuses from events or the Spiral Abyss. This formula is widely used by the theorycrafting community and has been validated against real player data from multiple game patches.

Formula
Total Primogems = (Current Primogems) + (Welkin Days × 90) + (Days × Commissions Per Day × 15) + (Abyss Cycles × 600) + (Event Primogems) + (Genesis Crystals × 1)

Each variable in the formula represents a distinct income source that the game tracks separately. The Welkin Moon provides 90 Primogems per day for each day remaining on the subscription. Daily commissions reward 10 Primogems per commission, and with 4 commissions per day, that equals 40 Primogems from commissions plus an additional 20 Primogems from the daily commission reward (total 60 Primogems per day, which is 15 Primogems per commission completed). Spiral Abyss resets twice per month, awarding up to 600 Primogems per reset for full completion of floors 9-12. Event rewards vary by patch but typically range from 420 to 1,680 Primogems. Finally, if you purchase the Welkin Moon, you receive 300 Genesis Crystals immediately, which can be converted 1:1 into Primogems.

Understanding the Variables

To use the formula correctly, you must understand what each input represents and how to obtain those numbers in-game. Current Primogems is your exact balance shown in the Paimon menu—this is your starting point. Welkin Days is the number of days remaining on your Welkin Moon subscription, which you can verify by checking the subscription icon in the Battle Pass screen. Days is your chosen projection period, typically the number of days until a specific banner ends or until you plan to wish. Commissions Per Day is the average number of daily commissions you complete—most players use 4, but if you skip some days, average it out. Abyss Cycles counts how many Spiral Abyss resets occur within your projection period (each reset is two weeks, so a 30-day period includes 2 cycles). Event Primogems is your estimate of total Primogems from all ongoing and upcoming events during the projection period. Genesis Crystals is the amount you receive from the Welkin Moon purchase (300 per purchase) or from other Genesis Crystal top-ups, converted at a 1:1 ratio.

Step-by-Step Calculation

First, start with your current Primogem count. Then multiply the number of remaining Welkin days by 90 to get the total Welkin income over the projection period. Next, multiply the number of days in your projection by your average daily commission completions, then multiply that result by 15 (since each commission gives 10 Primogems and the daily bonus gives 20 Primogems, the average per commission is 15). Add any Spiral Abyss rewards by multiplying the number of reset cycles by 600. Add any event Primogems you expect. Finally, add any Genesis Crystals you have converted to Primogems. Sum all these values to get your total projected Primogems. To convert to Intertwined Fates, divide the total Primogems by 160 (since one wish costs 160 Primogems). The calculator performs all these steps instantly, but understanding the logic helps you verify the results and adjust inputs intelligently.

Example Calculation

Let us walk through a realistic scenario that a typical Genshin Impact player might face. Imagine you are saving for the upcoming banner of the Hydro Archon Furina, which is rumored to arrive in 14 days. You currently have 2,400 Primogems saved, you have 12 days remaining on your Welkin Moon subscription, and you always complete all 4 daily commissions. You also plan to complete the Spiral Abyss once during this period, and you expect the current flagship event to give 420 Primogems.

Example Scenario: Current Primogems: 2,400 | Welkin Days Remaining: 12 | Projection Period: 14 days | Daily Commissions: 4 | Abyss Cycles: 1 | Event Primogems: 420 | Genesis Crystals: 0 (already converted)

Step 1: Start with your current Primogems: 2,400. Step 2: Calculate Welkin income: 12 days × 90 Primogems = 1,080 Primogems. Step 3: Calculate daily commission income: 14 days × 4 commissions × 15 Primogems per commission = 840 Primogems. Step 4: Add Spiral Abyss: 1 cycle × 600 Primogems = 600 Primogems. Step 5: Add event rewards: 420 Primogems. Step 6: Sum everything: 2,400 + 1,080 + 840 + 600 + 420 = 5,340 total Primogems. Step 7: Convert to wishes: 5,340 ÷ 160 = 33.375 wishes, meaning you will have 33 Intertwined Fates and 60 leftover Primogems.

In plain English, after 14 days of saving with your Welkin Moon active, you will have 5,340 Primogems, enough for 33 wishes. This puts you well past soft pity (which starts at 75 wishes) if you have some wishes already saved, or it gives you a strong start toward the 90-pull hard pity. You will need approximately 42 more days of similar saving to reach the 90-pull guarantee, or about 84 days to reach the 180-pull guarantee if you lose the 50/50.

Another Example

Consider a different scenario: a new player who just purchased the Welkin Moon for the first time and wants to know how many Primogems they will have in 30 days. They start with 0 Primogems, have 30 Welkin days remaining, and plan to complete 4 commissions daily. They do not expect to complete Spiral Abyss yet, and no major events are running. Their calculation: 0 current Primogems + (30 × 90 = 2,700 Welkin Primogems) + (30 × 4 × 15 = 1,800 commission Primogems) + 0 Abyss + 0 events + 300 Genesis Crystals (from the Welkin purchase) = 4,800 total Primogems. This equals exactly 30 Intertwined Fates (4,800 ÷ 160 = 30). With 30 wishes, this new player has a decent chance at pulling a 5-star character if they are within the first 75 wishes of pity, and they will have enough for several 4-star characters and weapons along the way. This example shows how the Welkin Moon alone, combined with daily play, can generate a meaningful number of pulls over a single month.

Benefits of Using Genshin Impact Welkin Calculator

Using a dedicated Genshin Impact Welkin Calculator transforms the way you manage your in-game resources, turning vague estimates into precise, actionable data. This tool is not just a convenience—it is a strategic advantage that can save you real money and in-game frustration. Below are the five key benefits that make this calculator indispensable for any Genshin Impact player who purchases the Welkin Moon.

  • Accurate Banner Planning: The calculator tells you exactly how many Primogems you will have by a specific banner end date, removing the guesswork from saving. Instead of checking your Primogem count daily and wondering if you will make it, you get a definitive number. This allows you to decide whether to skip a current banner to guarantee a future character, or to pull now if the numbers show you will still have enough for your target. Many players have avoided spending unnecessary money on Genesis Crystals simply by knowing their exact projected income.
  • Time-Saving Convenience: Manually calculating Primogem income across multiple sources—Welkin, commissions, Abyss, events, and battle pass—is tedious and error-prone. Our calculator does all the math in under a second, freeing you to focus on actually playing the game. You can run multiple scenarios in seconds, comparing "what if I skip Abyss this cycle" versus "what if I complete all floors." This rapid iteration helps you optimize your play schedule without mental arithmetic.
  • Budget Optimization for Real Money: If you are considering purchasing additional Genesis Crystals or another Welkin Moon, the calculator shows you exactly how many more Primogems you need to reach your pity goal. You can see whether buying a small top-up pack will bridge the gap, or if waiting a few more days for Welkin income is sufficient. This prevents overspending on unnecessary purchases and helps you allocate your gaming budget more effectively.
  • Pity Tracking Integration: Many players forget their current pity count or lose track after multiple 10-pulls. The calculator includes a pity tracker input where you can enter your current wish count on the banner. It then tells you how many additional wishes you need to reach soft pity (75), hard pity (90), and the guarantee (180). This contextual information turns raw Primogem numbers into meaningful progress indicators, motivating you to save consistently.
  • Event and Abyss Scheduling: By including event and Abyss rewards in the projection, the calculator helps you plan your weekly and monthly activities. If the calculator shows you are 200 Primogems short of your goal, you know you need to complete the Spiral Abyss or finish the current event. This turns vague "I should do events" into a specific, measurable target. Over time, this habit maximizes your free-to-play income and ensures you never miss a reward that could have secured your desired character.

Tips and Tricks for Best Results

To get the most accurate projections from your Genshin Impact Welkin Calculator, apply these expert-level tips that go beyond basic input. These strategies come from veteran players who have used similar tools across multiple game patches and banner cycles. Following these guidelines will make your projections reliable enough to base real purchasing decisions on.

Pro Tips

  • Always update your current Primogem count immediately after spending any Primogems—even a single 10-pull changes your projection significantly. Set a reminder to check your balance every time you wish, and update the calculator before making any purchase decision.
  • Use the "Days Until Banner Ends" feature by checking the official Genshin Impact social media or in-game notice for exact banner end dates. Do not assume banners last exactly 21 days, as some events or patch extensions can alter the schedule by a few days.
  • For event rewards, use conservative estimates. Instead of assuming you will get the maximum 1,680 Primogems from a patch event, assume 1,260 (75% of max) to account for missed days or difficult challenges. This buffer prevents disappointment if you cannot complete every event task.
  • If you are saving for a specific character's rerun, check the historical pattern: most reruns occur 4-6 months after the original banner. Plan your Welkin purchases accordingly—buying one Welkin Moon per month for 4 months gives you about 12,000 Primogems (75 wishes), which is often enough to guarantee a 5-star character if you win the 50/50.
