Genshin Impact Primogem Calculator

Saving for a banner comes down to counting: days of commissions, Spiral Abyss and Imaginarium Theater resets, and how much Welkin Moon you have left before the character arrives. Enter what you have and what you earn, and the calculator counts the actual resets between your start date and the banner, converts everything at 160 Primogems per wish, and checks whether you will reach the wishes that guarantee a featured 5★.

How to use this tool

1. Enter the Primogems and Intertwined Fates you have now.
2. Set the start date and the days until the banner (one version is usually 42 days).
3. Tick Daily Commissions, add your Welkin Moon days, and set what you expect from Spiral Abyss, Imaginarium Theater and events.
4. Add your current pity to see if you will cover the worst case.

Formula

Wishes = floor(total Primogems ÷ 160) + Intertwined Fates

Total Primogems = current + 60 × days (commissions) + 90 × Welkin days + Abyss reward × resets on the 16th + Theater reward × resets on the 1st + other income. Paimon's Bargains Fates are added once per month on the 1st.

Example

Starting on 1 November 2026 with 1,600 Primogems and 5 Fates, saving for 42 days with commissions every day and 30 days of Welkin Moon: commissions give 2,520, Welkin 2,700, and the window holds one Abyss reset (16 November) and one Theater reset (1 December) at 800 each. That is 8,420 Primogems, or 52 wishes with 100 left over, plus the 5 Fates: 57 wishes by 13 December.
