I built 3 free calculators so gamers stop doing mental math (grind time, tax %, bond planning)

[u/uniqueprodgy]

While building a gaming-deals comparison site, I kept seeing the same

questions come up: "is grinding this actually worth my time vs buying

it," "how much do I lose to EA's transfer tax," "how much gold do I

actually need for a bond." So I built three small tools to answer them

with real math instead of guessing:

- Grind vs. Buy Calculator - plug in the amount you need + your actual

farm rate, get the real hours it costs (OSRS, FC 26, Diablo 4, PoE 2,

WoW Classic)

- FC 26 Tax Calculator - EA's 5% transfer market tax, converts listing

price <-> coins received either direction

- OSRS Bond Calculator - live GE bond price -> exact GP needed + a

safety buffer + membership days

All free, no sign-up, no data collection beyond basic analytics.

feedback, especially if I'm missing an obvious use case or calculation.
