Rental Property Calculator

Size up a California rental in one place. Enter the price, financing, rent, and expenses to see your monthly cash flow, cap rate, cash-on-cash return, and DSCR — the numbers a DSCR lender actually uses.

Estimate. Operating expenses = taxes, insurance, management, maintenance, HOA (not the mortgage). DSCR = NOI ÷ annual debt service.

What this rental calculator shows

This tool runs the four numbers investors and DSCR lenders care about: monthly cash flow (rent minus expenses and mortgage), cap rate (unleveraged yield), cash-on-cash return (leveraged cash yield on your invested cash), and DSCR — the debt-service coverage ratio a lender uses to approve the loan. A DSCR of 1.0 means the property’s income exactly covers the payment; most DSCR programs want 1.0–1.25+, and many allow lower ratios with more down.

Rental Property Calculator FAQ

What DSCR do I need to qualify?

Most DSCR loan programs look for a ratio of at least 1.0 (the rent covers the full payment), and price best at 1.25 or higher. Some programs allow ratios below 1.0 — even down to about 0.75 — with a larger down payment and stronger credit.

How does this calculator compute cash flow?

It calculates your monthly principal-and-interest payment from the price, down payment, rate, and term, then subtracts it and your operating expenses from the vacancy-adjusted rent.

What operating expenses should I include?

Property taxes, insurance, property management, maintenance/repairs, HOA, and utilities you pay — but not the mortgage payment (that’s counted separately) and not one-time capital expenditures.

Can I use projected short-term rental income?

Some DSCR lenders will use short-term (Airbnb) rental projections, which can raise the DSCR. See our guide on Airbnb and short-term rental loans for how that income is counted.
