Rusty Pilot Math — Aircraft Operating Cost Calculator

Know exactly what it costs to fly before you ever leave the ground.

Rusty Pilot Math is the aircraft operating cost calculator built for pilots and aircraft owners who want a clear, honest picture of their true cost of ownership. Stop guessing. Stop under-budgeting. Know your real numbers.

Track Every Cost — Fixed and Variable

Fixed costs don't stop when you're not flying. Insurance, hangar fees, loan payments, annual inspections, and subscriptions add up every month whether you fly or not. Rusty Pilot Math tracks all of it, prorated to a consistent monthly and annual figure so you always know where you stand.

When you do fly, log your variable costs — fuel, oil, maintenance, engine reserve, and landing fees — against your actual tach or Hobbs reading. The app uses those readings to calculate your real cost per flight hour based on how much you actually flew, not an estimate.

True Cost Per Flight Hour

Most pilots underestimate their hourly cost. Rusty Pilot Math calculates it the right way — by dividing your actual monthly costs (fixed + variable) by the actual hours flown that month, based on tach readings. The result is an honest, accurate cost per hour that updates as you fly.
