The numbers below are examples so you can see how it works. They are not industry averages. Replace them with yours.
Some entries need fixing. Anything marked is counted as 0 until you fix it.
The aircraft
What it earns and how much it flies.
Cost of each hour flown
Costs that rise and fall with flying.
Overhaul reserves
Money to set aside each hour so the engine and prop are paid for when they come due. Leave at 0 if you do not reserve.
Fixed costs
What you pay whether the airplane flies or not.
Advanced inputs
Optional. Use these for overhead and for an accounting view.
What if you changed something?
Each change is tested on its own against your numbers above. Results show on the right.
Cash contribution per month
$0
Where the money goes
One month at your current hours.
Break-even
Monthly cash contribution at different billable hours.
What changes the number
Monthly and yearly effect on cash contribution. Bars go right when it helps.
A rate increase assumes the same hours. In real life a higher rate can cost you some hours. Downtime assumes the lost hours are not made up later.
