How to Use This Calculator

  1. Enter your gross game fee — the amount the school or league sends to you or your assignor before any cuts.
  2. Set the assignor fee — use the percentage field (leave flat at 0) or enter a flat dollar amount if your chapter charges a fixed fee per game.
  3. Enter round-trip distance — the full round trip from your home to the gym and back, in miles or km depending on your unit toggle.
  4. Adjust the cost-per-mile/km rate — the default is the 2026 IRS business mileage rate (72.5¢/mi). You can lower this if your car is cheap to run, or raise it for high-fuel vehicles.
  5. Enter your annual dues — include state association fees (e.g. WOA, IHSA, etc.) plus local chapter dues. They'll be prorated per game.
  6. Fill in time fields — drive time, pre-game prep, game time, and post-game. This reveals your real effective hourly rate.
  7. Read your net per game, effective hourly rate, and season totals — all update instantly.
Formula used:
Gross = game fee + mileage reimbursement received + other income
Assignor deduction = flat fee if > 0, else game fee × assignor %
Mileage cost = round-trip distance × cost per distance unit
Dues per game = annual dues ÷ games per season
Total deductions = assignor + mileage cost − mileage reimbursement + dues per game + gear per game + other
Net per game = gross game fee − total deductions
Total time (hours) = (2 × one-way drive + prep + game + post) ÷ 60
Effective hourly = net per game ÷ total time

Frequently Asked Questions

Why is my basketball referee net pay much lower than my game fee?

Several deductions chip away at your gross game fee before it becomes real take-home money: an assignor commission (typically 5–10%), round-trip driving costs calculated at the IRS mileage rate, prorated annual association dues, and optional uniform/equipment amortization. A $60 game fee with a 24-mile round trip, an 8% assignor cut, and $150/year in dues spread across 40 games can realistically net under $40 per game. Knowing these numbers is the first step to deciding whether to accept assignments, negotiate fee increases, or cluster games to reduce mileage.

What is the IRS standard mileage rate for 2026?

The IRS set the 2026 standard business mileage rate at 72.5 cents per mile, effective January 1, 2026 — up 2.5 cents from the 2025 rate of 70 cents per mile (IRS Notice 2026-10). Basketball referees who work as independent contractors can use this rate on Schedule C to calculate their deductible vehicle expenses. Note that W-2 employees cannot deduct unreimbursed mileage under current law. This calculator defaults to 72.5¢/mi but lets you override it with your actual fuel-and-wear cost per mile.

How much do assignors typically charge basketball referees?

Most referee assignors charge 5% to 10% of the referee's gross game fee. In some regions 7–8% is the local norm; in others 10% is standard. Some chapters use a flat dollar amount per game instead. The fee compensates the assignor for scheduling, managing availability, communicating last-minute changes, and handling payments. This calculator lets you enter either a percentage or a flat amount, using whichever your chapter applies.

How do I calculate my effective hourly rate as a basketball official?

Divide your net pay per game (after all deductions) by your total time invested per assignment in hours. Total time = 2 × one-way drive time + pre-game arrival time + game duration + post-game time. A 72-minute game with a 20-minute one-way drive and 30 minutes of pre/post time equals about 2.2 hours total. A net of $44 in 2.2 hours works out to roughly $20/hour — useful context when comparing officiating to other part-time work or deciding how far to travel.

Should I track mileage to every basketball game for tax purposes?

Yes — if you file as a self-employed contractor (which most grassroots basketball referees do), game-related driving is deductible on Schedule C at the IRS standard mileage rate. You must maintain a contemporaneous log recording the date, destination, and miles driven for each trip. A mileage app or spreadsheet works fine. The 2026 rate of 72.5¢/mile means every 100 miles driven to games gives you a $72.50 deduction — significant over a full season.

Does working a double-header improve my effective hourly rate?

Yes, significantly. When you work two games in one trip, you pay the mileage cost and drive time only once, but collect two game fees (minus two sets of assignor deductions and two prorated dues amounts). In this calculator, set the mileage to zero for the second game of a shared trip to model the improved economics. Double-headers and tournament days are the easiest lever to raise your true hourly rate without increasing per-game fees.

Are basketball referee association dues tax-deductible?

Generally yes for independent contractors — annual association dues paid to join an officiating chapter are a legitimate business expense deductible on Schedule C. This includes state official registration fees, local chapter dues, and any mandatory training fees, as long as you are working as a self-employed contractor rather than an employee. Always confirm with a tax professional for your specific situation.
