Leaseback Engine

Know your exact breakeven hour before you sign anything.

Most owners learn what leaseback really costs after they've already committed. The Leaseback Engine shows you the full revenue waterfall, operator economics, and breakeven hours before the ink dries.

  • Wet vs. dry lease modeling — see how fuel responsibility shifts the math.
  • % split or flat-fee operators — model any commission structure.
  • Visual breakeven progress bar — target hours vs. required hours, at a glance.
  • Full revenue waterfall — gross revenue → operator cut → reserves → net contribution.

Multi-Stage P&L

A full income statement every owner can read.

Aircraft accounting is its own dialect. The Multi-Stage P&L speaks it fluently — every line item categorized correctly, every per-hour cost shown, side-by-side with and without leaseback.

  • Year 1 through Year 5 — see how the numbers age with reserves and amortization.
  • With vs. without leaseback — overlaid 5-year cash position chart.
  • Per-hour and annual columns — both views of every cost.
  • Scenario sensitivity table — no LB, current, breakeven, profitable side by side.

FAQ

Questions, answered.

Is this a flight training tool?
No. The Owner Intelligence Suite is a financial modeling tool for aircraft owners, buyers, and leaseback operators. Narber Aviation runs a separate flight instruction business out of Des Moines, Iowa, but the Suite is a standalone SaaS product — you don't need to be a student or pilot in training to use it.
How accurate are the calculations?
Every calculation uses the same single source-of-truth function. Financing uses standard amortization; reserves are computed from your TBO inputs; leaseback economics include operator splits, insurance surcharge, and per-hour variable costs. The tax shield model is intentionally simplified — Section 179 and bonus depreciation have complex passive-loss and recapture rules. Always validate with a qualified aviation CPA before signing anything.
What's included with the subscription?
Full access to all five tabs (Dashboard, Acquisition & Costs, Leaseback Model, Tax Shield & ROI, Multi-Stage P&L), all 28 aircraft presets, unlimited saved profiles, unlimited PDF exports, dark and light themes, and continuous feature updates. No per-user fees, no per-aircraft fees, no usage caps.
How does the free trial work?
There is no free trial. The Suite is paid access only — your login arrives by email immediately after checkout. We made this choice deliberately: free trials attract tire-kickers and the people who get the most out of this tool are owners and serious buyers who know what they're looking for. Cancel any time from the Stripe customer portal.
Can I model a leaseback that's not commercial?
Yes. The Leaseback Engine has a master toggle — turn it off and the Suite becomes a pure cost-of-ownership report. Hourly costs, fixed costs, reserves, and tax shield all still work. Turn it back on when you're ready to model commercial use, club rental, or 1099 leaseback to a flight school.
Will my data sync across devices?
Yes. Profiles save to your account and load on any device you sign in from. Use desktop for full editing and mobile for quick what-if modeling on the ramp.
Who built this?
Ethan Narber — a CFI in Des Moines, Iowa, running Narber Aviation, LLC. The Suite started as a private spreadsheet for his own ownership math, grew into a tool he kept being asked to share, and is now available as a paid product. Feedback goes straight to him.
