📊 Starglitter Cost vs. Acquired 4-Star Characters per Month

What is Genshin Impact Starglitter Calculator?

A Genshin Impact Starglitter Calculator is a specialized free online tool designed to help players determine exactly how many Masterless Starglitter they will earn from pulling duplicate characters and weapons in Genshin Impact. This currency is one of the most valuable resources in the game because it allows you to purchase high-value items like additional Constellation levels for 4-star characters, the monthly rotating 4-star characters, and the coveted Blackcliff series weapons from Paimon's Bargains. Without a calculator, players often underestimate or overestimate their Starglitter income, leading to poor pull decisions or missed opportunities to acquire a must-have character constellation before the shop resets.

Active Genshin Impact players—especially those who are saving Primogems for upcoming banners or planning to pull multiple copies of a featured 4-star character—use this tool to forecast their Starglitter balance before spending any wishes. It is also essential for theorycrafters and F2P players who need to maximize every resource. This free online Genshin Impact Starglitter Calculator eliminates guesswork by instantly computing your Starglitter earnings based on your current pity count, banner type, and the number of wishes you plan to make, giving you a clear financial picture before you pull.

How to Use This Genshin Impact Starglitter Calculator

Using this calculator is straightforward and requires no signup or login. You only need a few pieces of information from your game account to get an accurate projection of your Starglitter earnings. Follow these five simple steps to generate your personalized Starglitter forecast.

  1. Enter Your Current Pity Count: Open your Genshin Impact wish history or check your last pull. Look for the number of wishes since your last 5-star character or weapon. Enter this number (0 to 89 for character banners, 0 to 79 for weapon banner) into the "Current Pity" field. This is critical because soft pity dramatically increases your 4-star and 5-star drop rates, which directly affects how many duplicate items you get.
  2. Select Your Banner Type: Choose from the dropdown menu which banner you are pulling on: "Character Event Wish," "Weapon Event Wish," or "Standard Wish." Each banner has different mechanics—the Weapon banner has Epitomized Path that guarantees a specific 5-star weapon after two lost 50/50s, while the Character banner has a 50/50 system for the featured 5-star. These differences affect how often you receive duplicates and thus how much Starglitter you earn.
  3. Input Your Target Wishes: Enter the total number of Intertwined Fates or Acquaint Fates you plan to use. This can be any number from 1 to 999. Be realistic—if you have 50 wishes saved, enter 50. The calculator will simulate the pulls and tally all the Starglitter you would earn from every duplicate 3-star, 4-star, and 5-star item.
  4. Adjust the Constellation Duplicate Factor (Optional): If you already have a specific 4-star character at C6, toggle the "C6 4-star character" option and select which character. When you pull a duplicate of a C6 4-star character, you receive extra Starglitter (5 instead of 2). This feature makes the projection much more accurate for veteran players with maxed-out 4-star rosters.
  5. Click "Calculate Starglitter": Press the bright orange button and wait less than a second. The tool instantly displays your total estimated Starglitter, a breakdown by rarity (3-star, 4-star, 5-star duplicates), and a summary of how many of each item type you will likely receive. You can also see a detailed pull-by-pull log if you want to verify the math.

For best results, make sure your pity count is accurate—check your wish history in-game rather than guessing. If you are pulling on the Weapon banner, remember that the Epitomized Path system can shift your Starglitter earnings if you get an off-banner 5-star weapon you already own at R5, which gives extra Starglitter.

Formula and Calculation Method

The calculator uses a probabilistic simulation based on Genshin Impact's official drop rates and pity mechanics, not a simple static formula. This is necessary because Starglitter earnings are highly dependent on random outcomes and the soft pity system. However, the core calculation for each individual pull follows a deterministic conversion: every duplicate item you receive is converted into Starglitter at a fixed rate set by miHoYo. The formula for total Starglitter earned from a single pull is:

Formula
Total Starglitter = (Number of 3-star Duplicates × 0) + (Number of 4-star Duplicates × 2) + (Number of 5-star Duplicates × 10) + (Number of C6 4-star Character Duplicates × 5) + (Number of R5 5-star Weapon Duplicates × 10)

This formula is applied for every pull in the simulation, but the "Number of Duplicates" is determined by the game's gacha logic. The calculator runs a Monte Carlo simulation with 10,000 iterations to give you the most probable outcome. Each variable in the formula represents a specific in-game mechanic. Understanding these variables helps you interpret the results correctly and adjust your pulling strategy.

Understanding the Variables

The first variable, "3-star Duplicates," always yields 0 Starglitter. Every 3-star weapon you pull is converted into 15 Masterless Starglitter, not Starglitter—these are different currencies. The calculator ignores 3-star items because they only give Starglitter, not Starglitter. The second variable, "4-star Duplicates," covers any 4-star character or weapon you already own at least one copy of. Each duplicate gives exactly 2 Masterless Starglitter. The third variable, "5-star Duplicates," applies to any 5-star character or weapon you have pulled before. Each duplicate of a 5-star item gives 10 Masterless Starglitter. The fourth variable, "C6 4-star Character Duplicates," is a special case: if you have a 4-star character at Constellation 6, any further copy of that character gives 5 Masterless Starglitter instead of 2. The fifth variable, "R5 5-star Weapon Duplicates," is the weapon equivalent—if you already have a 5-star weapon at Refinement Rank 5, a duplicate gives 10 Starglitter (same as a standard 5-star duplicate) but the game treats it as a special case for the shop.

Step-by-Step Calculation

First, the calculator determines the outcome of each pull by rolling a random number against the drop rate table. For example, on the Character Event Wish, the base 4-star rate is 5.1% with a soft pity that increases after 9 consecutive non-4-star pulls. If the roll lands on a 4-star, the calculator then checks if it is a featured character (50% chance) or a non-featured character/weapon. Next, it checks your inventory: if you already own that character or weapon, it adds 2 Starglitter (or 5 if it is a C6 4-star character). If you do not own it, it adds 0 Starglitter. The same logic applies to 5-star pulls, which have a base rate of 0.6% with soft pity starting at pull 74. After simulating all your entered wishes (e.g., 100 wishes), the calculator sums up all the Starglitter earned from duplicates and presents the average across 10,000 simulations. This gives you a highly reliable estimate, usually within 10% of your actual result.

Example Calculation

To make this concrete, let us walk through a realistic scenario that a typical Genshin Impact player might face. Imagine you are a Welkin Moon player who has been saving for the Raiden Shogun rerun banner. You have 120 Intertwined Fates saved, your current pity is 45 (meaning you have made 45 wishes since your last 5-star character), and you are pulling on the Character Event Wish banner. You have the 4-star character Kujou Sara at C6 already, and you want to know how much Starglitter you will earn to buy the Blackcliff Pole from Paimon's Bargains (costs 24 Starglitter).

Example Scenario: 120 wishes on Raiden Shogun banner, current pity = 45, Kujou Sara at C6, no other C6 4-star characters, no 5-star duplicates owned. You want to know if you will earn at least 24 Starglitter.

Step 1: The calculator simulates 120 pulls. It first checks soft pity for 4-star items—since you have not pulled a 4-star in 9 wishes (pity 45 means your last 4-star was at pull 36), the next pull (pull 46) has an elevated 4-star rate. In the simulation, you get your first 4-star at pull 47. It is a Favonius Lance (a weapon). You already own this weapon, so you earn 2 Starglitter. Step 2: You continue pulling. At pull 74, soft pity for 5-star kicks in. The calculator rolls a 5-star at pull 76—it is Raiden Shogun (you do not own her), so 0 Starglitter for that pull. Step 3: Over the remaining 44 pulls, you get 6 more 4-star items. Two of them are Kujou Sara duplicates (since she is C6, each gives 5 Starglitter = 10 total). The other four are weapons and non-featured characters you already own, giving 2 Starglitter each = 8 total. Step 4: You also get a second 5-star at pull 112 (a loss to Diluc, who you already own), earning 10 Starglitter. Total Starglitter = 2 + 10 + 8 + 10 = 30 Starglitter. The calculator's average across 10,000 simulations is 28.4 Starglitter. This means you will almost certainly afford the Blackcliff Pole (24 Starglitter) and have 4-6 Starglitter leftover.

In plain English, this result tells you that with 120 wishes and your current pity, you can safely expect to earn enough Starglitter to buy one Blackcliff weapon from the shop, assuming you have at least one C6 4-star character on the banner. If you did not have Kujou Sara at C6, your Starglitter would drop to around 22, which might not be enough—so the calculator helps you decide whether to pull more or wait.

Another Example

Consider a different scenario: a pure F2P player with 50 wishes, zero pity (0/90), pulling on the Standard Wish banner. They have no C6 characters and no 5-star duplicates. The calculator simulates 50 pulls with base rates. On average, you will get about 3-4 four-star items and 0 five-star items. Each 4-star duplicate gives 2 Starglitter, so total Starglitter is around 6-8. This is enough to buy one 3-star weapon from the shop or save for a 4-star character. The result shows that F2P players should not expect significant Starglitter income from small wish counts—saving 150+ wishes is needed to reliably earn 24 Starglitter for a Blackcliff weapon.

Benefits of Using Genshin Impact Starglitter Calculator

This free tool offers substantial advantages for any Genshin Impact player, from casual collectors to hardcore theorycrafters. Instead of relying on rough mental math or outdated spreadsheets, you get a precise, data-driven forecast that respects all the game's intricate pity mechanics. Here are the five key benefits that make this calculator indispensable for strategic resource management.

  • Eliminates Pull Regret: The most common mistake players make is spending wishes without knowing how much Starglitter they will earn, only to realize they are 2 Starglitter short of buying a desired character constellation when the shop resets. This calculator prevents that disappointment by giving you a realistic lower bound and average estimate before you spend a single Fate. You can confidently pull knowing you will meet your Starglitter target.
  • Optimizes Constellation Planning: If you are aiming for a specific 4-star character's C6, the calculator shows you exactly how many wishes you need to pull to get enough Starglitter to buy the remaining constellations from the shop (if the character is in Paimon's Bargains that month). For example, if you need 2 more copies of Xiangling to reach C6, the tool can tell you if pulling 80 wishes will yield at least 6 Starglitter to buy her from the shop.
  • Supports F2P and Low-Spender Budgeting: Free-to-play players have extremely limited Primogem income. Using this calculator, you can plan your wish spending months in advance. For instance, you can calculate that saving for 3 patches will give you roughly 180 wishes, which yields about 40-50 Starglitter on average—enough to buy two Blackcliff weapons or one 4-star character constellation. This helps you decide which banners to skip.
  • Accounts for C6 and R5 Bonuses: Veteran players with maxed-out 4-star rosters often underestimate how much extra Starglitter they earn. The calculator's C6 toggle feature reveals that a player with 8 C6 4-star characters can earn 50% more Starglitter per 100 wishes compared to a new player. This knowledge can change your pulling strategy—you might pull on a banner with multiple C6 4-star characters specifically to farm Starglitter.
  • Saves Time and Mental Energy: Manually calculating Starglitter involves tracking pity, drop rates, and duplicate status for dozens of items. This tool does the heavy lifting in under a second, giving you a clear, printable report. You can use that saved time to enjoy the game itself rather than doing gacha math on a spreadsheet.

Tips and Tricks for Best Results

To get the most accurate and useful results from the Genshin Impact Starglitter Calculator, follow these expert tips derived from years of community testing and game mechanic analysis. Small adjustments in your input can significantly change your projected Starglitter, so pay attention to these details.

Pro Tips

  • Always verify your current pity by checking the in-game wish history menu—do not rely on memory. Even a 1-pity difference can shift your 5-star pull by several wishes, altering your Starglitter total by up to 10.
  • If you are pulling on the Weapon banner, enable the "Epitomized Path" toggle in the calculator if available. This feature accounts for the fact that after two lost 50/50s, your third 5-star is guaranteed to be the chosen weapon, which affects how many duplicate 5-star weapons you might get (and thus Starglitter).
  • Use the "C6 Character" input for every 4-star character you have at C6, not just the featured ones. Off-banner 4-star characters you have at C6 also give 5 Starglitter when they appear, and the calculator needs this data for accuracy.
  • Run the simulation multiple times with different wish counts (e.g., 50, 100, 150) to see how Starglitter scales. You might find that 120 wishes gives you 28 Starglitter but 130 wishes gives 34—that extra 10 wishes could be worth it for a second Blackcliff weapon.
  • Bookmark the calculator and use it before every major pulling session. Starglitter shop rotations happen on the 1st of every month, so check the calculator a few days before to see if you need to pull more or hold your Fates.
