Primogem, Fate & Pity Calculator
Estimate how many wishes you can make and your chance of pulling featured 5★ characters on the limited banner.
This tool is for planning. Probability uses an approximate soft-pity model and Monte Carlo simulation.
If you have ever asked, “Do I have enough pulls for the next character?” this Genshin Impact calculator is built for exactly that moment. Instead of doing wish math manually every patch, you can enter your resources and instantly see how many pulls you can make, where your pity ends, and your estimated odds to hit your featured target.
What this Genshin Impact calculator does
The calculator combines your current and planned resources, then converts everything into total wishes:
- Primogems and Genesis Crystals convert at 160 per wish.
- Intertwined Fates are counted directly as wishes.
- Masterless Starglitter is converted to extra wishes at 5 per fate.
- Your current pity and guarantee status are used to estimate outcome odds.
Why pity planning matters
In Genshin Impact, randomness is never truly random over a long enough timeline because the pity system places an upper limit on bad luck. You might not know exactly when you will hit a 5★, but you usually know the maximum number of pulls required to get one.
Character event banner basics
- Hard pity happens at 90 wishes for a 5★.
- If you lose the 50/50, your next 5★ on that banner type is guaranteed featured.
- If you are already guaranteed, one full pity cycle is often enough to secure the character.
Simple “worst-case” checkpoints
Many players use two quick checkpoints for planning:
- Up to 90 pulls: secure any 5★ from character banner pity.
- Up to 180 pulls: secure one featured 5★ if you are not guaranteed.
The calculator gives these checkpoints alongside a probability estimate, helping you decide whether to pull now or keep saving.
How to use the calculator correctly
Step 1: Enter only character banner pity
Pity does not carry between different banner types. Character event, weapon, and standard each track pity separately. This calculator is designed for character event wish planning.
Step 2: Include realistic future primogems
If a banner has two weeks left, include your expected commissions, events, Abyss, and shop reset income. Avoid overestimating. It is better to undercount and be pleasantly surprised.
Step 3: Set your target copies
Use 1 for C0 planning, 2 if you want C1 total copies from zero, and so on. The chance output tells you your probability of reaching at least that many featured copies with your entered wishes.
Interpreting your results
After calculating, focus on these fields:
- Total wishes available: your actual pull budget.
- Hard-pity floor: minimum number of 5★ units if hard pity is all you hit.
- Ending pity: where you will stop if you spend all wishes.
- Estimated success chance: practical probability for your target copies.
If your chance is low and the character is essential for your account goals, it may be smarter to skip and save for rerun certainty.
Common mistakes this calculator helps prevent
- Forgetting Starglitter can buy extra wishes.
- Mixing standard banner pity with limited character pity.
- Ignoring current guarantee status from a previous lost 50/50.
- Pulling based on “feel” without checking the true odds.
A practical planning framework
When to pull aggressively
If you are guaranteed and have close to one pity cycle, pulling can be very efficient. You may even keep enough leftover pity for future banners if luck arrives early.
When to hold resources
If you are not guaranteed and far below a two-cycle reserve, stopping can be the disciplined move—especially when your target character has known rerun patterns or if multiple future characters are high priority.
For free-to-play and low spenders
Resource discipline is your biggest advantage. Building a habit of checking this calculator before every banner can prevent emotional pulls and improve long-term roster quality.
FAQ
Does this include weapon banner logic?
No. Weapon banner has different pity and Epitomized Path behavior, so the math differs significantly.
Why do probability values change slightly each click?
The calculator uses Monte Carlo simulation. Small variance is normal and expected. The general estimate remains useful for decision-making.
Is this an official tool?
No. This is a fan-made planning calculator and is not affiliated with HoYoverse.
Final note
Good pulls feel amazing, but smart planning feels even better. Use this Genshin Impact calculator as your pre-banner checklist: count resources, verify pity, check guarantee, and pull only when the numbers support your goal.
