Fight Purse Calculator

Manager and trainer fees are calculated only against 'fight earnings' — the guaranteed purse plus any win bonus — and the calculator deliberately excludes sponsor/endorsement income from that base. That models how cornermen contracts are typically structured around the fight purse itself, with sponsorship deals usually negotiated and paid separately, outside the corner's percentage cut.

If 'Won the fight?' is set to no, the win bonus is excluded from total gross entirely, and since manager and trainer fees are calculated on fight earnings (purse plus bonus), those fees shrink too — losing removes both the bonus itself and the corner team's cut of it. Only the guaranteed purse and sponsor income remain, so a loss typically has an outsized effect on take-home pay whenever the win bonus made up a large share of the total.

The calculator treats camp costs and the athletic commission fee as deductible business expenses, so taxable income is total gross minus those two items — not the full gross amount. That lowers the taxable base before the tax percentage is applied, similar to how self-employed fighters can typically deduct legitimate training and licensing expenses before calculating owed tax.

No — it always divides net earnings by a fixed 3 rounds regardless of the scheduled or actual fight length, which can run anywhere from 3 rounds (amateur/some pro bouts) to 12 rounds (title fights). Treat it as a rough per-round reference point rather than a literal calculation tied to your specific fight's round count.
