How to Use the Event Farming vs Paid Efficiency Calculator
Every limited-time event brings the same question: can free farming alone get you to the goal, or is it worth spending a little? This calculator multiplies event length by daily free income to find your expected total from farming alone, then compares it against your target to find any shortfall.
If there's a shortfall, it uses the yield and price of a single paid purchase to automatically calculate how many purchases you'd need and the total cost. And if free farming is already enough, you'll see that in hard numbers instead of guessing — which helps avoid impulse spending you didn't actually need.
Goals that look comfortable early in an event often start feeling tight as time runs out. Re-checking your remaining days and shortfall with this calculator as the event nears its end can help you avoid last-minute panic spending.
If a shop offers several different purchase bundles, run each one through the calculator separately to compare which bundle gives you the best value per dollar for closing your specific shortfall.
Frequently Asked Questions
If daily free income multiplied by the event length meets or exceeds your target, the shortfall shows as 0 — meaning you can hit the goal without spending anything.
If there's a late-event bonus or multiplier period, enter a blended average for daily free income to get a more realistic result.
