Rental & Investment Property Calculator
Estimate down payment and loan amount, monthly principal and interest, rental income, vacancy, management, maintenance and CapEx reserves, taxes, insurance, HOA and utilities, NOI, monthly and annual cash flow, cap rate, cash-on-cash return, DSCR, and total initial cash investment. Every assumption is editable, and every percentage tells you what it is calculated on. Defaults are moderately conservative starting points — replace them with your own numbers.

Results
Annual property taxes and annual insurance are required to finish this calculation. We never estimate them for you — enter your own annual amounts (or 0 if you truly expect none) to see NOI, cap rate, DSCR, cash flow, and cash-on-cash return.
Enter an interest rate to calculate debt service, DSCR, cash flow, and cash-on-cash return.

Returns
Cash required
Cash at closing = down payment + closing costs. Total initial cash investment adds upfront rehab paid in cash and is the denominator for cash-on-cash return.
How these numbers are calculated. Vacancy = % of scheduled rental income (monthly rent × 12). Management = % of effective collected rental income after vacancy. Maintenance covers recurring repairs and turnover. CapEx reserve covers long-life replacements such as roofs, HVAC, windows, plumbing systems, and major appliances; it is shown separately, excluded from NOI and cap rate, and deducted when calculating investor cash flow. Operating expenses include taxes, insurance, HOA, owner-paid utilities, management, and maintenance. NOI excludes mortgage principal and interest, income taxes, depreciation, closing costs, rehab, and CapEx reserves. Cap rate = NOI ÷ purchase price (before debt service and before CapEx reserves). DSCR = annual NOI ÷ annual debt service. Lender DSCR calculations may differ based on lender-specific underwriting rules. Nothing here is a lending, accounting, tax, or investment recommendation.
