About this calculator

Method, formulas, and limits.

What this does

Estimates the capitalization rate (cap rate), net operating income (NOI), implied property value, and cash-on-cash return for rental and commercial properties. Simple mode provides a quick cap rate from rent and expenses, while Pro mode supports itemized expense breakdowns and NOI-driven underwriting to find either cap rate or property value.

Who it is for

Real estate investors, rental property owners, and commercial underwriters who need to compare deal profitability. Also useful for anyone evaluating a property purchase and wanting to see how financing affects cash-on-cash return.

How it works

The calculator derives NOI from either direct input or itemized rent and expenses, then divides by property value to get the cap rate. For the value task, it solves for property value from a target cap rate and NOI. An optional mortgage block adds leverage: the calculator subtracts debt service from NOI and divides by cash invested to compute cash-on-cash return.

Limitations

Cap rate ignores financing (unless the mortgage block is used), taxes, depreciation, capital improvements, and tenant turnover costs. The benchmark ranges are general guides and may not reflect your specific market or property class.

Key calculations

Cap rate
Cap rate = NOI divided by property value.
NOI
NOI = gross rental income - vacancy loss - operating expenses.
Cash-on-cash
Cash-on-cash return = annual cash flow after debt / cash invested.

How to use it

  1. 1.Choose the modeUse simple mode for residential rentals or pro mode for NOI-driven underwriting.
  2. 2.Enter income and costsAdd rent, NOI, or itemized expense details depending on the active view.
  3. 3.Review the benchmarkRead the cap rate against the selected residential or commercial range.
  4. 4.Add mortgage assumptionsExpand the optional mortgage block to compare annual cash flow and cash-on-cash return.

There is no universal good number. The result depends on property type, risk, financing, and local market conditions, so the calculator compares your result against a common residential (4–10%) or commercial (5–12%) range. A good cap rate in a hot urban market may be considered weak in a secondary market, which is why context matters more than a single target.

Divide annual net operating income (NOI) by the property value or purchase price. For example, a property with $50,000 NOI and a $625,000 price has an 8% cap rate. The calculator handles both directions: enter NOI and value to find the cap rate, or enter NOI and a target cap rate to find the implied property value.

Not always. A higher cap rate can signal more yield, but it can also reflect more risk, weaker tenant quality, higher operating volatility, or a less desirable location. Lower cap rates in prime areas may produce better risk-adjusted returns even though the percentage looks smaller.

Cap rate ignores financing entirely—it values the property based on NOI relative to price regardless of how you fund the purchase. Cash-on-cash return includes leverage by subtracting annual debt service from NOI and dividing by your actual cash invested (down payment). A property with an 8% cap rate might deliver a 12% cash-on-cash return with favorable financing, or only 4% with expensive debt.

NOI is the income left after vacancy loss and operating expenses (property taxes, insurance, repairs, management, utilities, HOA). It does not include debt service, income taxes, depreciation, capital improvements, or tenant improvements. Using consistent NOI definitions is important because different investors include or exclude different line items.

Yes. Save the active scenario into the compare tray to line up up to three deals and review the cap rate, NOI, benchmark label, and cash-on-cash return side by side. Each scenario preserves its inputs, so you can flip between simple and pro modes or different property types and compare the results on a single screen.

Simple mode asks for monthly rent and a single operating expense figure—it is designed for quick residential rental checks. Pro mode supports an itemized expense breakdown (taxes, insurance, repairs, management, utilities, HOA, other) and adds NOI-driven tasks like finding property value from a target cap rate or solving for cap rate when you already know the NOI.
