Rental ROI Calculator
Plug in the property. Out comes the deal.

Every detail engineered.
Property Calculator
Single-property deep analysis. Plug in purchase price, rent, expenses. Cap rate, cash-on-cash, GRM, 1% rule, 50% rule, DCR, total return — every metric, live. Big STRONG BUY / MARGINAL / PASS badge.
Multi-Property Compare
Side-by-side grid for 5 properties. Best Cap Rate + best Cash-on-Cash highlighted in green automatically. The grid does the comparing — you just pick the winner.
360-Month Amortization
Full mortgage schedule. Beginning balance, payment, principal, interest, ending balance — every month. Total interest paid over the life of the loan is the number that scares first-time investors.
30-Year Cash Flow
Year-by-year projection with rent growth, expense growth, and property value growth. Year 30 shows total wealth created — cash flow plus appreciation plus principal paydown.
Repair / CapEx Reserves
25 major systems with replacement cost and lifespan pre-loaded. Annual reserve auto-calculates. Items due in the next 5 years flag amber. Don't get blindsided by a roof.
After-Tax Cash Flow
Depreciation, deductions, after-tax cash flow. Most rental calculators skip this — it's where the real returns hide. Configure your tax bracket once in Settings.
Real sheets. Real data. Real returns.
