HoYoLAB Wish & Primogem Planner
Estimate how many wishes you can save before a banner ends, then compare that to your target pulls in a worst-case pity scenario.
Assumptions: 160 primogems = 1 wish, hard pity at 90, and worst-case 50/50 outcomes when not guaranteed.
What is a HoYoLAB calculator?
A HoYoLAB calculator is a planning tool players use to estimate resources before a limited banner arrives or ends. Most people use it to answer one question: “Will I have enough pulls for the character I want?” Instead of guessing, a calculator combines your current resources with expected daily and patch income to build a realistic pull forecast.
While HoYoLAB itself offers useful account and event tracking, many players still prefer a dedicated wish calculator because it gives a clear, pull-focused projection. This page does exactly that with an easy, transparent formula.
How this hoyolab calculator works
1) It estimates total primogem income
Your final primogem total is built from:
- Current primogems already in your account
- Daily commissions over the remaining banner days
- Welkin Moon daily rewards (if active)
- Spiral Abyss resets in your planning window
- Event rewards, maintenance compensation, and livestream codes
2) It converts currency into total wishes
After summing primogems, the calculator converts them into wishes at a rate of 160 primogems per pull, then adds your existing Intertwined Fates and any shop fates you expect to buy.
3) It compares your wishes to pity requirements
The final step estimates pull requirements under a worst-case hard pity model: 90 pulls for a 5-star and up to 180 pulls per featured copy when 50/50 is involved. This conservative approach helps avoid overconfidence when saving.
When to use this planner
- Before deciding whether to pull now or skip for a future banner
- When comparing C0 vs C1/C2 goals
- When choosing between weapon banner and character banner priorities
- At the start of each patch to set a realistic primogem budget
Example planning flow
Let’s say you have 5,000 primogems, 12 fates, 28 days left, Welkin active for all days, and 2 Abyss resets. Add event/codes/maintenance rewards and your calculator output might show 95–120 total pulls depending on assumptions. If you are not guaranteed, that may still be short for a true worst-case featured guarantee. Seeing that gap early gives you options: skip weapon banner, increase Abyss effort, or delay for rerun safety.
Tips to improve calculator accuracy
Use conservative event estimates
It is better to slightly underestimate than overestimate. Missing events, fewer Abyss stars, or skipped dailies can reduce your real total quickly.
Track your pity and guarantee status carefully
Pity count and guarantee state have a huge impact on required pulls. Entering these incorrectly can make your plan look much safer than it actually is.
Recalculate weekly
Resource planning is not a one-time action. Update your numbers every week to reflect new events, redeemed codes, and your actual play consistency.
FAQ
Is this an official HoYoLAB tool?
No. This is an independent planning calculator inspired by common HoYoLAB community use cases.
Does this include soft pity probability?
Not in the result model. It intentionally uses hard-pity worst-case math for safer budgeting. Actual outcomes may be better, but this method minimizes disappointment.
Can this be adapted for other HoYoverse games?
Yes. The planning logic (current currency + daily income + event rewards + pity state) works across multiple titles. You can swap variable names for Stellar Jades, Polychromes, or other banner currencies.
Final takeaway
A good hoyolab calculator is less about perfect prediction and more about making disciplined pull decisions. Use it to set clear goals, estimate worst-case needs, and avoid impulse spending when a banner looks tempting. With consistent tracking, your savings strategy becomes calm, intentional, and far more effective.
