Methodology
How to Calculate Real Estate ROI: Cap Rate, Cash-on-Cash, and Total Return uses the amortization, escrow, rate, fee, and housing-cost formulas documented on the page, then layers loan-program or property-cost assumptions when the user provides them.
Assumptions
- How to Calculate Real Estate ROI: Cap Rate, Cash-on-Cash, and Total Return relies on the values the user enters and does not independently verify income, balances, legal status, policy terms, or market quotes.
- Loan rates, fees, taxes, insurance, PMI or MIP, HOA dues, and closing costs are planning inputs unless a lender quote is supplied.
- The calculator assumes scheduled payments are made on time and that extra payments are applied according to the selected scenario.
Limitations
- How to Calculate Real Estate ROI: Cap Rate, Cash-on-Cash, and Total Return does not approve a loan, lock a rate, quote closing costs, determine program eligibility, or replace a Loan Estimate from a lender.
- Property taxes, insurance, HOA dues, PMI or MIP, lender overlays, credit score, and local fees can materially change the payment or cash-to-close.

Professional guidance: How to Calculate Real Estate ROI: Cap Rate, Cash-on-Cash, and Total Return is for housing-finance education only and is not mortgage, legal, tax, or underwriting advice. Confirm rates, fees, eligibility, and cash-to-close with a lender or housing professional.
Real estate investing uses several different return metrics, each answering a different question. Cap rate measures the property's earning power. Cash-on-cash return measures your leveraged return. Total ROI captures the full picture including appreciation and equity buildup.
Step 1: Net Operating Income (NOI)
NOI = Gross Rental Income − Operating Expenses Operating expenses include property taxes, insurance, maintenance, property management (8-10%), vacancy allowance (5-8%), and repairs. Do NOT include mortgage payments.
Example: A duplex generates $2,400/month in rent ($28,800/year). Operating expenses total $10,800/year. NOI = $28,800 - $10,800 = $18,000.
Step 2: Cap Rate
Cap Rate = NOI / Purchase Price × 100 Cap rate is independent of financing — it measures the property's intrinsic return.
For the duplex purchased at $300,000: Cap Rate = $18,000 / $300,000 = 6.0%. Use the Cap Rate Calculator for a full deal analysis.
Step 3: Cash-on-Cash Return
Cash-on-cash measures the leveraged return on your actual cash invested. If you put 20% down ($60,000) plus $5,000 in closing costs ($65,000 total cash), and annual mortgage payments are $14,400:
Annual Cash Flow = $18,000 NOI - $14,400 debt service = $3,600. CoC = $3,600 / $65,000 = 5.5%.

- Total ROI includes appreciation, equity buildup, tax benefits, and cash flow combined.
- Leverage amplifies returns — a 6% cap rate can produce 15%+ total ROI with good financing.
