How to Use the Stamina Refill vs Natural Recovery Calculator
When your stamina (or energy) runs out in a mobile game, you're often stuck choosing between buying an instant refill or simply waiting for it to regenerate naturally. This calculator takes the refill item's price, how much stamina it restores, your natural recovery speed, and the value of your own time, then tells you which option is the better deal from a purely financial standpoint.
The core idea is that waiting isn't free either. Converting the time it takes to naturally recover the same amount of stamina into an hourly rate gives you the "opportunity cost of waiting." If that cost is higher than the item's price, buying the refill is actually the more economical choice. If it's lower, waiting costs you less overall.
Keep in mind this is a pure dollars-and-cents comparison - real decisions should also weigh context like whether you need to play right now or whether a limited-time event makes resource efficiency especially important. When you do have time to spare, use the result to cut back on unnecessary spending.
Frequently Asked Questions
Use your actual hourly wage, or the cash-equivalent value of what you'd otherwise be doing with that time. If you're unsure, entering a minimum-wage estimate still gives a useful rough comparison.
This calculator only compares pure monetary cost. If you're short on time and need to play right now, buying the item can still be the more sensible choice even if the math favors waiting.
Most games show 'time until next point' near the stamina UI. Convert that into minutes required per single stamina point and enter it here.
