Cap Rate Calculator for Rental and Commercial Real Estate
Cap Rate Calculator
A cap rate calculator is a real estate valuation tool that divides a property’s annual net operating income (NOI) by its market value to show its unlevered yield. Pick USD or CAD first. You’ll then type in rent and vacancy, add operating expenses line by line, and the tool hands back NOI and the capitalization rate. It also estimates value at whatever target rate you choose.

Cap rate = NOI ÷ value × 100 · Value = NOI ÷ cap rate
Key Takeaways
- Cap rate equals net operating income divided by current market value, expressed as a percentage.
- NOI excludes mortgage payments, depreciation, capital cost allowance (CCA) and income taxes.
- The same formula solves for value: NOI divided by the cap rate equals property value.
- A good cap rate depends on property type, city and interest rates, so compare it against local survey data.
- Cap rate ignores financing. Use cash-on-cash return or internal rate of return (IRR) to measure leveraged returns.
- A Chatham rate cap calculator prices interest rate caps on loans, not capitalization rates.
What Is Cap Rate in Real Estate?
Cap rate in real estate is the capitalization rate, the ratio of a property’s annual net operating income to its current market value, which shows the yield an all-cash buyer would earn in the first year of ownership, before any loan costs. Take a property producing $60,000 of NOI and valued at $1,000,000. Its cap rate is 6%. Rents drive NOI, so check the best cities to rent in Canada.
Appraisers rely on cap rates too. The income approach to value, which is one of the three standard appraisal methods, converts a property’s income into an estimate of value using a cap rate.
In cap rate commercial real estate analysis, brokers and lenders in the USA and Canada quote cap rates to compare income-producing properties across markets. It’s their shared shorthand. New to this? Read how to invest in real estate in Canada.
How Is Cap Rate Calculated?
Cap rate is calculated by dividing annual net operating income by the property’s current market value and multiplying the result by 100 to express it as a percentage, so $75,000 of NOI on a $1,250,000 property produces a 6% cap rate.
The Cap Rate Formula
Cap rate = Net operating income ÷ Current market value × 100
Whether an investor asks how to figure out cap rate or how do I calculate cap rate, the math comes down to one division of income by value. The formula rearranges two ways:
- Property value = NOI ÷ cap rate
- Required NOI = property value × cap rate
Purchase Price vs Market Value
Buyers weighing an offer use purchase price. An owner tracking an existing asset should use current market value instead, since an old purchase price distorts the yield once values change. For current values, see the average house price in Canada.
How to Use the Cap Rate Calculator
To use the cap rate calculator, enter gross potential rent, a vacancy allowance, other income and each operating expense, then enter the purchase price or market value, and the tool returns NOI, the cap rate and a value sensitivity table.
- Select USD or CAD as the currency.
- Enter gross potential rent for 12 months at full occupancy.
- Apply a vacancy and credit loss percentage based on local rental data.
- Add other income such as parking, laundry or storage fees.
- Enter annual operating expenses line by line.
- Enter the purchase price or current market value.
- Review NOI, the cap rate and the implied value at each target cap rate.
Calculator Inputs and Outputs Explained
The calculator inputs are the income and expense lines that build net operating income, and the outputs are NOI, the cap rate and implied property values, so every result traces back to a specific input field that the user can adjust and test.
Inputs
This table lists each input field and what it should contain.
| Input Field | What to Enter |
|---|---|
| Gross Potential Rent ($) | Annual rent at full occupancy and market rent |
| Vacancy and Credit Loss (%) | Expected empty units and unpaid rent |
| Other Income ($) | Parking, laundry, storage and pet fees |
| Property Taxes ($) | Annual municipal or county tax bill |
| Insurance ($) | Annual property and liability premiums |
| Maintenance and Repairs ($) | Routine upkeep, not major capital projects |
| Management Fees ($) | Third-party fee, or market rate if self-managed |
| Replacement Reserves ($) | Annual set-aside for roofs, HVAC and appliances |
| Property Value ($) | Purchase price or current market value |
Outputs
Four figures come back. Those are effective gross income, total operating expenses, NOI and the cap rate, each one calculated straight from the inputs you entered.
There’s a sensitivity view too. It shows the implied property value at cap rates 0.5 percentage points above and below the entered rate, so you can see how much a small shift moves the price.
How Do You Calculate NOI?
You calculate NOI by subtracting vacancy, credit loss and all annual operating expenses from gross potential rent plus other income, which leaves the annual cash a property generates from operations before mortgage payments, depreciation and income taxes are taken out.
Build NOI from trailing twelve months (T-12) statements whenever you want actual results rather than a seller’s hopeful estimate of what the building might earn. Pro forma NOI is a projection, not fact.
Watch for loss-to-lease. That’s the gap between in-place rents and current market rents, and it tells you whether today’s income understates what the units could bring in.
Expenses to Exclude from NOI
This table shows which costs belong in NOI and which do not.
| Cost | In NOI? | Reason |
|---|---|---|
| Property taxes | Yes | Recurring operating cost |
| Insurance | Yes | Recurring operating cost |
| Management fees | Yes | Required even if self-managed |
| Replacement reserves | Yes | Lenders often underwrite reserves |
| Mortgage principal and interest | No | Financing cost, not operating cost |
| Depreciation or CCA | No | Non-cash tax deduction |
| Income taxes | No | Owner-specific, not property-specific |
| Major capital improvements | No | Funded by reserves instead |
Worked Examples in USD and CAD
The two worked examples show how to calculate cap rate for a US fourplex and how to estimate the value of a Canadian apartment building, using hypothetical figures chosen for illustration rather than market data from any specific city or survey.
US Fourplex Example
Picture a 4,800 sq ft (446 m²) fourplex where each of the four units rents for $1,800 per month, which works out to $86,400 a year at full occupancy. This table builds NOI line by line.
| Line Item | Amount (USD) |
|---|---|
| Gross potential rent | $86,400 |
| Vacancy at 5% | -$4,320 |
| Effective gross income | $82,080 |
| Property taxes | -$9,000 |
| Insurance | -$3,200 |
| Maintenance | -$5,000 |
| Management at 8% | -$6,566 |
| Replacement reserves | -$2,000 |
| Net operating income | $56,314 |
Now divide. At a $900,000 purchase price, the cap rate is $56,314 ÷ $900,000 = 6.26%, which is the unlevered first-year yield before any mortgage enters the picture.
Canadian Multifamily Example
A 12-unit Ontario building rents each unit for C$1,750 per month, which adds up to C$252,000 of gross potential rent over a full year. Subtract the rest. A 4% vacancy allowance (C$10,080) and C$96,000 of operating expenses leave NOI of C$145,920. Market conditions vary, so check the real estate market by province.
This table compares the implied value at three cap rates.
| Cap Rate (%) | Implied Value (CAD) |
|---|---|
| 5.0 | C$2,918,400 |
| 5.5 | C$2,653,091 |
| 6.0 | C$2,432,000 |
That spread matters. A one-point move in the cap rate, from 5.0% to 6.0%, changes this building’s value by C$486,400 even though the income stays exactly the same.
Leave closing taxes out of NOI. Ontario’s land transfer tax and Toronto’s municipal land transfer tax are acquisition costs paid once at purchase, not recurring operating expenses.
What Is a Good Cap Rate?
A good cap rate is one that meets or exceeds the market rate for the same property type, building class and city while reflecting the risk of the tenants and the building, because no single percentage works as a universal benchmark across the USA and Canada.
Skip the rules of thumb. No verified figure available supports a single “good” number such as 6%. For current ranges, check CBRE’s U.S. Cap Rate Survey for American markets and Altus Group’s Canadian investment research for deals in Canada.
This table compares common factors and their effect on cap rates.
| Factor | Effect on Cap Rate |
|---|---|
| Prime metro (Toronto, Vancouver, New York) | Lower cap rate |
| Long leases with creditworthy tenants | Lower cap rate |
| Newer building, little deferred maintenance | Lower cap rate |
| Rising interest rates | Upward pressure |
| Secondary market or weak demand | Higher cap rate |
| Short leases or high turnover | Higher cap rate |
Cap Rate vs Cash-on-Cash Return vs IRR
Cap rate is the best metric for comparing property prices on an unlevered basis, cash-on-cash return is the best metric for measuring first-year cash yield on the equity invested, and IRR is the best metric for multi-year returns including projected sale proceeds and loan paydown.
This table compares five common real estate return and valuation metrics.
| Metric | Formula | Includes Financing | Best Use |
|---|---|---|---|
| Cap rate | NOI ÷ property value | No | Pricing and comparing properties |
| Cash-on-cash return | Pre-tax cash flow ÷ cash invested | Yes | First-year leveraged yield |
| IRR | Rate setting net present value to zero | Yes | Multi-year hold analysis |
| Gross rent multiplier (GRM) | Price ÷ gross annual rent | No | Quick screening |
| Debt service coverage ratio (DSCR) | NOI ÷ annual debt service | Yes | Loan qualification |
Chatham Rate Cap Calculator vs Cap Rate Calculator
A Chatham rate cap calculator estimates the cost of an interest rate cap, a hedge that limits the interest rate on a floating-rate loan, while a cap rate calculator measures a property’s NOI relative to its value, so the two tools answer different questions.
Chatham Financial works in financial risk management. It publishes the rate cap tool for borrowers whose floating-rate loans are tied to benchmarks such as the Secured Overnight Financing Rate (SOFR).
Plenty of commercial borrowers run both. Cap rate tells them what the asset is worth, while rate cap pricing helps them budget financing costs on floating-rate debt before they close.
Tips for Accurate Cap Rate Results
Accurate cap rate results come from verified T-12 operating income and expense figures, realistic vacancy and management assumptions, and a value that reflects today’s market, because small input errors change the cap rate and the implied value by large amounts.
- Request the seller’s T-12 statement and rent roll before trusting a listed cap rate.
- Charge a market management fee even if you self-manage.
- Budget reserves for roofs, furnaces, boilers and appliances, especially in cold-climate markets.
- Re-estimate property taxes at the new price, because some US states reassess after a sale.
- Compare cap rates only within the same property type and city.
- Run the cap rate calc at higher and lower rates to test value sensitivity.
- Compare replacement properties by cap rate during a US 1031 exchange. Canada has no direct equivalent under Canada Revenue Agency (CRA) rules.
Frequently Asked Questions
Investors tend to come back with the same follow-ups once they’ve run a cap rate calculation on a real deal. Here are five.
Is a Higher Cap Rate Better?
No. A higher cap rate means more income per dollar of value, but it usually signals more risk. Weaker tenants and older buildings push the rate up, and so does a location in a secondary market with thinner buyer demand.
Do You Include Mortgage Payments in NOI?
No. NOI measures how the property performs before financing, so mortgage principal and interest stay out of the NOI calculation entirely. Debt costs show up in cash-on-cash return and DSCR instead.
Does Cap Rate Apply to Single-Family Rentals?
Yes. Cap rate works for any income-producing property, single-family rentals and house hacks included. Keep one caveat in mind, though: single-family values often track nearby home sales more closely than they track rental income.
Why Do Cap Rates Rise with Interest Rates?
Higher interest rates raise borrowing costs and lift the returns investors expect from alternatives such as bonds, so buyers pay less for the same NOI. The link isn’t rigid. Cap rates don’t always move in lockstep with rates.
Does a Good Cap Rate Differ by City?
Yes. Demand and expected rent growth vary by market, and so does risk. Properties in Toronto and Vancouver generally trade at lower cap rates than those in smaller Canadian markets, and New York follows the same pattern against smaller US markets.
