Rent Return Calculator

A rent return calculator tells you what a rental property actually earns you, after the costs most investors forget. Enter the purchase price and monthly rent, choose the return measure you care about, and the tool below computes rental yield, cap rate, cash-on-cash return or a full total-return projection with appreciation. Expense and mortgage inputs appear only when the selected measure needs them.

How Rental Return Math Works

Investors judge a rental with five related measures. This tool computes all of them and highlights the one you selected:

• Gross rental yield = (annual rent / purchase price) x 100. The quick screen: a $250,000 property renting for $2,200 a month yields ($26,400 / $250,000) x 100 = 10.56% before any costs.
• Net rental yield = (annual rent – operating expenses) / purchase price x 100. Expenses include property taxes, insurance, maintenance, a vacancy allowance and management fees. This is the honest version of gross yield.
• Cap rate = net operating income / property price x 100, where net operating income is rent minus operating expenses. It ignores financing, so you can compare two properties on their own merits.
• Cash-on-cash return = annual cash flow / cash invested x 100. Cash flow is net operating income minus mortgage payments, and cash invested is your down payment plus closing costs. This is the number that matters to a leveraged buyer.
• Total return analysis adds appreciation: future value = price x (1 + appreciation rate)^years, plus all the rent collected over the holding period, converted to an annualized rate of return.

Monthly cash flow = (net operating income / 12) – monthly mortgage payment, and the mortgage payment uses the standard amortization formula. The break-even rent row shows the monthly rent needed for zero cash flow: monthly mortgage payment plus operating expenses divided by 12.

Worked Example: A $250,000 Rental at $2,200 a Month

Run the tool in Net Rental Yield mode with these inputs:

• Purchase price $250,000; monthly rent $2,200 (annual rent $26,400)
• Down payment $50,000; closing costs $5,000
• Property taxes $3,000; insurance $1,200; maintenance $1,800; vacancy 5% ($1,320); management 8% ($2,112)
• Loan $200,000 at 6.5% over 30 years (monthly payment $1,264.14)

Total operating expenses come to $9,432, so net operating income is $26,400 – $9,432 = $16,968. The tool reports a net rental yield of 6.79%, a cap rate of 6.79%, monthly cash flow of $149.86 and annual cash flow of $1,798.37. Total cash invested is $55,000, the break-even rent is $2,050.14 a month, and the ROI rating reads “Good”. Switch to Total Return Analysis with 3% annual appreciation over 10 years: projected future value $335,979.09, total rental income $264,000.00, capital appreciation $85,979.09, total return $349,979.09, annualized return 20.33%.

What Other Rental Return Calculators Miss

We read the top-ranking rental ROI tools before writing this page. The pattern is consistent:

• Explainer sites (the most common ranking pages) publish the ROI formula and a worked example but give you no working tool, so every number above would have to be computed by hand.
• Single-measure tools compute ROI or cap rate alone. They cannot tell you the cash-on-cash return on your down payment, and they stop at the annual snapshot with no multi-year projection.
• No appreciation modeling. Most rental calculators ignore future property value entirely, even though appreciation is often the largest part of a rental’s total return. This tool’s Total Return Analysis mode projects it explicitly.
• No break-even rent. The rent level at which a property stops bleeding cash is one of the most practical numbers an investor can know, and almost no free tool shows it.
• No plain-language verdict. Competitors hand you a percentage and leave the interpretation to you. The ROI rating (Poor through Excellent) tells you at a glance where the deal sits.

This page covers every measure the competitors offer, adds the appreciation projection and break-even rent, and puts copy and share buttons on the results. To compare financing options side by side, use the mortgage payment calculator for the exact monthly payment behind each cash flow figure. The cap rate calculator goes deeper on the unleveraged yield measure, and landlords sizing commercial space can check rentable square footage when the rent is quoted per square foot.

Frequently Asked Questions

What is a good rental ROI?

Most real estate investors treat 8% to 12% cash-on-cash as a strong target, while 4% to 6% is acceptable in expensive, high-appreciation markets. The tool’s ROI rating follows a similar scale: 12% and above rates Excellent, 8% Very Good, 6% Good and 4% Fair. Always compare against what your cash would earn elsewhere.

What is the difference between cap rate and cash-on-cash return?

Cap rate divides net operating income by the property price and ignores financing, so it measures the property itself. Cash-on-cash return divides annual cash flow (after mortgage payments) by the cash you actually invested, so it measures your money. A property can have a modest cap rate and an excellent cash-on-cash return if it is heavily leveraged.

Does this calculator include appreciation?

Only in Total Return Analysis mode, where you set the annual appreciation rate and holding period. The other four modes measure income returns only, which is the standard convention: appreciation is a forecast, not a cash flow.

What is break-even rent?

The monthly rent at which the property’s cash flow is exactly zero: monthly mortgage payment plus one-twelfth of annual operating expenses. In the worked example it is $2,050.14 a month. Any rent above that produces positive cash flow; any rent below it means you are subsidizing the property.

Why is my cash flow negative when the yield looks good?

Because yield and cash flow answer different questions. Gross yield ignores both expenses and debt. If your mortgage payment is large relative to the rent, cash flow can be negative even at a 10% gross yield. That is exactly why the tool shows both numbers side by side.

Does this include income taxes?

No. The tool does not model income tax, depreciation deductions, or capital gains tax on sale, all of which materially change after-tax returns. Treat the results as a pre-tax screening analysis and discuss the tax picture with a qualified tax professional before buying.
