What is Genshin Primogem Calculator?

A Genshin Primogem Calculator is a specialized free online tool that estimates the total number of Primogems a player can earn within a specific time frame in Genshin Impact. It aggregates all known in-game sources of Primogems—such as Daily Commissions, Spiral Abyss resets, events, exploration, and Battle Pass rewards—and provides a realistic projection of your future Primogem income. This tool is essential for free-to-play (F2P) and low-spending players who want to plan their wishes for limited 5-star characters or weapons without making costly mistakes.

Primogems are the premium currency in Genshin Impact, used to purchase Intertwined Fates for character and weapon banners. Without a calculator, players often overestimate how many Primogems they can save before a banner ends, leading to disappointment or impulse spending. This tool helps you set achievable saving goals, prioritize which banners to pull on, and track your progress toward pity. It matters because each 5-star character costs approximately 28,800 Primogems at hard pity (180 wishes), and knowing your exact earning potential prevents wasted resources.

This free Genshin Primogem Calculator requires no signup or login. You simply input your current Primogem count, your desired target date, and select your activity level (casual, average, or hardcore). The tool instantly calculates your projected earnings using up-to-date event schedules and patch cycle data, giving you a clear roadmap for your next wish session.

How to Use This Genshin Primogem Calculator

Using this Primogem calculator is straightforward and takes less than two minutes. Follow these five simple steps to get an accurate projection of your future Primogem income and plan your wishes effectively.

  1. Enter Your Current Primogem Count: Open your Genshin Impact inventory and check the top-right corner for your current Primogem balance. Type this exact number into the "Current Primogems" field. Be honest—if you have 1,247 Primogems, enter 1247, not a rounded estimate. This base number is critical for accurate forecasting.
  2. Set Your Target Date: Choose the end date of the banner you are saving for. For example, if the upcoming Raiden Shogun banner ends on March 15, 2025, select that date. The calculator uses the number of remaining days to compute daily and weekly income sources. You can also set a custom date for long-term saving goals, like saving for a rerun six months away.
  3. Select Your Activity Level: Choose from three preset profiles: Casual (plays 15–30 minutes daily, does not complete Spiral Abyss floors 9–12), Average (plays 30–60 minutes daily, clears Spiral Abyss up to floor 11), or Hardcore (plays 1+ hours daily, full Spiral Abyss 36-star clears, completes all events and exploration). This selection adjusts the estimated Primogem yield from Spiral Abyss, events, and daily commissions. If you are unsure, start with "Average" and adjust later.
  4. Check Optional Income Sources: Toggle on or off specific income streams like Battle Pass (Gnostic Hymn or Battle Pass only), Welkin Moon (blessing of the welkin moon), or upcoming patch livestream codes. The calculator pre-fills typical values based on patch history but lets you customize. For example, if you plan to buy Welkin Moon next month, check that box and enter the start date.
  5. Click Calculate and Review Results: Press the "Calculate" button. The tool instantly displays your total projected Primogems, equivalent Intertwined Fates, and the number of wishes needed to reach soft pity (75) or hard pity (90). A progress bar shows how close you are to your goal. You can also see a daily breakdown—how many Primogems you need to earn each day to hit your target.

For best accuracy, update your current Primogem count weekly and re-run the calculation. The tool also saves your last session data locally in your browser, so you can return without re-entering everything. Use the "Reset" button to start fresh for a different banner goal.

Formula and Calculation Method

The Genshin Primogem Calculator uses a dynamic formula that combines fixed daily income, variable weekly income, and one-time event rewards. The core formula is based on official Genshin Impact patch cycles (typically 42 days) and community-agreed averages from sources like the Genshin Impact Fandom Wiki and the Wishing Well subreddit. The formula accounts for both guaranteed income (like Daily Commissions) and probabilistic income (like Spiral Abyss stars), ensuring realistic projections.

Formula
Total Primogems = Current Primogems + (Days_Remaining × Daily_Income) + (Weeks_Remaining × Weekly_Income) + Event_Income + Battle_Pass_Income + Welkin_Moon_Income + One_Time_Rewards

Each variable is calculated using sub-formulas that break down individual sources. For example, Daily_Income = 60 (Daily Commissions) + 0 (if no Welkin) or 90 (if Welkin active). Weekly_Income = 600 (Spiral Abyss full clear) + variable event rewards averaged per week. The tool uses a 7-day week and a 30.44-day month for consistency, matching the game's internal calendar.

Understanding the Variables

Current Primogems: Your exact in-game balance at the time of calculation. This is the starting point and directly impacts the final projection. Do not include Genesis Crystals unless you plan to convert them—the tool has a separate input for that.

Days_Remaining: The number of full days between today and your target date. The calculator uses midnight server time (UTC+8) to determine cutoffs. If a banner ends at 3:00 PM server time on March 15, that day counts as a full day for income calculation.

Daily_Income: This includes 60 Primogems from Daily Commissions (4 commissions × 10 Primogems each + 20 bonus from Katheryne). If you have Welkin Moon active, add 90 Primogems per day (claimed daily). If you have the Gnostic Hymn Battle Pass, add an average of 40 Primogems per day from BP levels (680 total over 42 days).

Weekly_Income: Spiral Abyss resets every two weeks (usually on the 1st and 16th of each month), but the calculator averages it weekly. A full 36-star clear gives 600 Primogems per reset (300 per half). Partial clears are estimated based on your activity level: Casual gets 0, Average gets 300 per reset, Hardcore gets 600. Additionally, weekly boss fights (3 bosses) drop 60 Primogems total per week from the Battle Pass system (BP missions).

Event_Income: Major patch events (like flagship events) typically give 420–980 Primogems over 7–14 days. The calculator uses the average from the last six patches: 720 Primogems per major event. Minor events (like Ley Line Overflow) give 120–420 Primogems. The tool assumes 2 major events and 2 minor events per patch, distributing them evenly across the remaining days.

Battle_Pass_Income: The Gnostic Hymn Battle Pass (paid) gives 680 Primogems total over 42 days. The free Battle Pass (Sojourner's Battle Pass) gives 160 Primogems. The calculator lets you toggle between "None," "Free BP," and "Gnostic Hymn."

Welkin_Moon_Income: Each Welkin Moon purchase gives 300 Genesis Crystals upfront (convertible to 300 Primogems) plus 90 Primogems daily for 30 days. The calculator tracks overlapping Welkin durations if you buy multiple.

One_Time_Rewards: These include version livestream codes (300 Primogems per patch), maintenance compensation (300–600 Primogems per patch), and new region exploration rewards (variable, up to 2,000 Primogems for a new zone). The tool estimates these based on the patch cycle—if you are saving for a patch that introduces a new area, it adds a flat 1,500 Primogems for exploration.

Step-by-Step Calculation

Step 1: Determine the number of full days until your target date. Subtract today's date from the target date using server time. For example, if today is February 1, 2025, and the target is March 15, 2025, that is 42 days (assuming February has 28 days).

Step 2: Calculate daily income. If you have Welkin Moon active, daily income = 60 (commissions) + 90 (Welkin) = 150 Primogems per day. Without Welkin, it is 60. Multiply by 42 days: 150 × 42 = 6,300 Primogems from daily sources.

Step 3: Calculate weekly income. 42 days equals 6 weeks. If you are Hardcore and full clear Spiral Abyss every reset, you get 600 Primogems per reset × 3 resets (since resets happen every 2 weeks, 42 days = 3 resets) = 1,800 Primogems. Add weekly boss BP missions: 60 Primogems per week × 6 weeks = 360 Primogems. Total weekly income = 1,800 + 360 = 2,160 Primogems.

Step 4: Estimate event income. Over 42 days, assume 2 major events (720 each) and 2 minor events (300 each) = 1,440 + 600 = 2,040 Primogems. Add one-time patch rewards: livestream codes (300) + maintenance (300) = 600 Primogems. Total event income = 2,040 + 600 = 2,640 Primogems.

Step 5: Add Battle Pass income. If you have Gnostic Hymn, add 680 Primogems. If free, add 160. Step 6: Sum everything: Current Primogems (say 1,000) + Daily (6,300) + Weekly (2,160) + Events (2,640) + BP (680) = 12,780 Primogems total. Divide by 160 to get wishes: 79.8 wishes—enough for soft pity on the character banner.

Example Calculation

Let's walk through a realistic scenario that a typical Genshin Impact player might face. This example uses real numbers from the Version 5.4 patch cycle, assuming a player wants to save for the upcoming limited 5-star character, Furina, whose banner is expected to run from March 4 to March 25, 2025.

Example Scenario: Sarah is a free-to-play player (no Welkin, no BP) who currently has 2,340 Primogems and 5 Intertwined Fates. She wants to know if she can reach soft pity (75 wishes) before Furina's banner ends. Today is February 10, 2025. The banner ends March 25, 2025. She plays daily (casual) but only clears Spiral Abyss floors 9–10 (300 Primogems per reset). She always completes all events.

First, calculate days remaining: From February 10 to March 25 is 43 days. Daily income: 60 Primogems × 43 = 2,580 Primogems. Weekly income: She gets 300 Primogems per Spiral Abyss reset. Over 43 days, there are 3 resets (Feb 16, Mar 1, Mar 16). 300 × 3 = 900 Primogems. Weekly boss BP missions give 60 Primogems per week × 6 weeks (43 days ≈ 6.1 weeks, rounded to 6) = 360 Primogems. Total weekly = 1,260 Primogems. Event income: Over 43 days, she will likely experience 2 major events (720 each = 1,440) and 2 minor events (300 each = 600). Plus one-time patch rewards: livestream codes (300) and maintenance (300) = 600. Total events = 1,440 + 600 + 600 = 2,640 Primogems. Battle Pass (free) gives 160 Primogems. Current Primogems: 2,340 plus 5 fates (5 × 160 = 800 Primogems equivalent) = 3,140 total Primogems in hand. Now sum: 3,140 (current) + 2,580 (daily) + 1,260 (weekly) + 2,640 (events) + 160 (BP) = 9,780 Primogems. Divide by 160 = 61.1 wishes. She needs 75 wishes for soft pity, so she is 13.9 wishes short. The calculator will show she needs to save an additional 2,224 Primogems or adjust her goal to a different banner.

This result means Sarah should not expect to guarantee Furina as a free-to-play player in this timeframe. She could consider buying Welkin Moon (which would add 90 × 43 = 3,870 Primogems plus 300 upfront = 4,170 total, bringing her to 13,950 Primogems or 87 wishes—enough for soft pity). The calculator helps her make this informed decision before spending money.

Another Example

Consider a different player: Jake is a low-spender who buys Welkin Moon and the Gnostic Hymn Battle Pass. He currently has 5,600 Primogems and wants to save for the Nahida rerun banner ending June 10, 2025. Today is April 1, 2025—70 days away. He is a hardcore player who full clears Spiral Abyss (600 per reset) and completes all content. Daily income: 60 (commissions) + 90 (Welkin) = 150 × 70 = 10,500 Primogems. Weekly income: Spiral Abyss: 600 per reset × 5 resets (70 days ≈ 5 resets) = 3,000. Boss BP: 60 × 10 weeks = 600. Total weekly = 3,600. Events: Over 70 days (roughly 1.67 patches), estimate 3 major events (720 each = 2,160) and 3 minor events (300 each = 900) plus 2 sets of patch rewards (600 each = 1,200) = 4,260. Battle Pass (Gnostic Hymn): 680 per patch × 2 patches = 1,360. Current Primogems: 5,600. Sum: 5,600 + 10,500 + 3,600 + 4,260 + 1,360 = 25,320 Primogems. That equals 158.25 wishes—enough for hard pity (180) with 21.75 wishes to spare. The calculator tells Jake he can comfortably guarantee Nahida and even have leftover wishes for a weapon banner attempt.
