How to Use the Gacha Pull Value Calculator
Enter pull price, drop probability, and reward value to instantly compare expected rewards and cost efficiency across 1, 10, and 100 pulls. Expected reward = pulls × probability × reward value. This shows how much value you get on average for each spending tier.
Understanding Cost Efficiency
Efficiency (%) shows what percentage of your spending comes back as reward value. An efficiency below 100% means spending statistically costs more than the expected reward. With identical price and probability, efficiency is always the same across all pull counts. If multi-pull bundles offer a discount, enter the lower per-pull price to compare.
How to Use It
Set reward value to the item's market price, in-game equivalent, or your personal valuation. Seeing the expected cost per reward helps you judge whether the gacha offers value for money before you spend.
Frequently Asked Questions
It is the average reward value from N pulls: N × probability × reward value per item.
