Analyze deals using income, leverage, expenses, and appreciation. Track cash flow, cap rate, and equity. Judge property performance before buying, refinancing, or selling confidently.
Enter property price, financing terms, rental income, expenses, appreciation, selling costs, and holding period. Results appear above this form after calculation.
Use this sample scenario to understand how the calculator behaves with common rental-property assumptions.
| Purchase Price | Monthly Rent | Cash Invested | Annual Cash Flow | Cap Rate | Total ROI |
|---|---|---|---|---|---|
| $250,000.00 | $2,600.00 | $84,500.00 | $4,540.47 | 6.90% | 79.02% |
Gross Annual Income
= (Monthly Rent + Monthly Other Income) × 12
Effective Gross Income
= Gross Annual Income × (1 − Vacancy Rate)
Annual NOI
= Effective Gross Income − Annual Operating Expenses
Monthly Mortgage Payment
= Standard amortization payment using loan amount, interest rate, and loan term
Cap Rate
= Annual NOI ÷ Total Project Cost × 100
Cash-on-Cash ROI
= Annual Cash Flow ÷ Cash Invested × 100
Net Sale Proceeds
= Future Property Value − Selling Costs − Remaining Loan Balance
Total ROI
= (Cumulative Cash Flow + Net Sale Proceeds − Cash Invested) ÷ Cash Invested × 100
Annualized ROI
= ((Total Cash Received ÷ Cash Invested)^(1 ÷ Holding Years) − 1) × 100
NOI excludes mortgage payments. Debt service is used afterward to calculate true cash flow.
ROI measures how much profit a property generates compared with the cash you invested. This calculator includes rent performance, expenses, financing, appreciation, and sale proceeds for a fuller picture.
Cap rate focuses on property performance before financing. Cash-on-cash return measures annual cash flow against the money you personally invested. One evaluates the asset; the other evaluates your leveraged return.
No. NOI usually excludes loan payments. It only considers income minus operating expenses. Mortgage payments are added later to calculate annual debt service and actual cash flow.
Yes. Vacancy helps keep projections realistic. Even desirable units can lose income from turnover, maintenance gaps, late move-ins, or seasonal demand shifts. Conservative underwriting improves deal decisions.
Cash invested usually includes the down payment, rehab budget paid from cash, and closing costs. It represents the capital you put into the deal before seeing any rent or resale proceeds.
It can improve total returns, but relying only on appreciation adds risk. Strong deals usually combine decent cash flow, acceptable leverage, manageable expenses, and realistic exit assumptions.
Break-even occupancy estimates the share of potential income needed to cover operating expenses and debt service. Lower values generally suggest more cushion against vacancies or rent pressure.
Export after testing different purchase prices, rents, or financing structures. Saved reports help compare properties side by side, support investment memos, and document your underwriting assumptions.
