How is this calculated?

This calculator uses compound interest formulas, historical market return assumptions, and standard financial planning methodologies to project your investment growth over time.

What rate of return should I assume?

A balanced portfolio has historically returned 7-10% annually before inflation (about 5-7% after). Conservative estimates use 6-7%, aggressive portfolios may assume 8-10%. Lower is safer for planning.

Should I invest or pay off debt first?

Pay off high-interest debt (above 7%) first. For lower-rate debt like mortgages, investing often makes more sense mathematically, but being debt-free has psychological benefits too.

Formula

How is cap rate calculated?

Cap Rate = Net Operating Income (NOI) ÷ Property Value × 100. A property generating $50,000 NOI valued at $650,000: cap rate = 7.7%. NOI includes all rental income minus operating expenses (taxes, insurance, maintenance, management, vacancy) but excludes mortgage payments. Cap rate measures unlevered return — what the property earns independent of financing, making it the standard comparison metric for commercial and investment properties.

Rate Ranges

What cap rate ranges indicate about risk and return?

3-5% cap rate: prime locations, strong tenants, low risk (downtown office, Class A apartments). 5-7%: good locations, moderate risk (suburban retail, B-class apartments). 7-10%: secondary markets or value-add properties with higher risk and higher return potential. 10%+: distressed properties, high-vacancy, or markets with declining demand. Lower cap rates mean higher prices relative to income — you are paying for safety and stability. Higher cap rates offer more income per dollar invested but carry more risk.

Limitations

What does cap rate NOT tell you?

Cap rate ignores: financing (leverage can make a 6% cap rate property return 12%+ on equity), appreciation potential (a 4% cap rate in a gentrifying neighborhood may outperform a 9% cap rate in a declining area), capital expenditures (a new roof or HVAC system is not in NOI), and tenant quality (one reliable tenant vs twelve unreliable ones at the same NOI). Use cap rate as a starting comparison, not a complete analysis.

Cap Rate Calculator: Evaluate Rental Property Profitability

Whether you are looking for a cap rate estimator, cap rate formula, free cap rate calculator, cap rate returns, or cap rate growth — this free cap rate calculator provides accurate estimates to help you plan and make informed financial decisions.

The capitalization rate (cap rate) is the most widely used metric for evaluating commercial and investment real estate. It measures the annual return you would earn if you purchased the property entirely with cash — providing a clean, leverage-independent comparison between properties.

Formula: Cap Rate = Net Operating Income (NOI) ÷ Property Price × 100

Enter the property's purchase price and NOI (rental income minus operating expenses, before mortgage) above. The calculator shows the cap rate and how it compares to market benchmarks.

How to Calculate Cap Rate Step by Step

Example: A duplex priced at $350,000. Gross rental income: $3,200/month ($38,400/year). Operating expenses: property tax $4,200, insurance $1,800, maintenance $3,000, vacancy (5%) $1,920, management $0 (self-managed). Total expenses: $10,920. NOI = $38,400 - $10,920 = $27,480. Cap rate = $27,480 ÷ $350,000 = 7.9%.

This 7.9% cap rate means the property generates 7.9 cents in net income for every dollar of purchase price — before financing costs. With leverage (mortgage), the cash-on-cash return will differ depending on your down payment and interest rate. See our Rental Property Calculator for leveraged returns.

Cap Rate Benchmarks by Property Type and Market

Property Type	Typical Cap Rate Range	What Drives the Range
Class A multifamily (urban)	4.0-5.5%	Low risk, strong demand, appreciation potential
Class B/C multifamily (suburban)	5.5-8.0%	Higher yield, moderate risk
Single-family rental	5.0-8.0%	Location-dependent, less scalable
Retail (strip mall)	6.0-9.0%	Tenant quality, lease length
Office (Class A)	5.5-7.5%	Post-COVID uncertainty, WFH impact
Industrial/warehouse	5.0-7.0%	E-commerce demand, low vacancy
Self-storage	5.5-8.0%	Recession-resistant, low maintenance

According to CBRE and Real Capital Analytics, national average cap rates compressed from 7-8% in 2010 to 5-6% by 2022, then expanded slightly to 5.5-7% in 2023-2025 as interest rates rose. Higher cap rates mean higher income yield but often signal higher risk, worse location, or deferred maintenance. Lower cap rates indicate premium locations with lower risk and stronger appreciation potential.

Cap Rate Limitations

Cap rate ignores financing: It assumes all-cash purchase. Two investors buying the same 7% cap rate property — one with cash, one with 25% down at 7% interest — will earn very different actual returns. Use cash-on-cash return for leveraged analysis.

Cap rate ignores appreciation: A 4.5% cap rate in a rapidly appreciating market (3-5% annual appreciation) may produce 15-20%+ total return. A 9% cap rate in a declining market may produce negative total return despite high income yield.

Cap rate is a snapshot: It reflects current NOI and current price. If rents are below market (upside potential) or above market (risk of decline), the cap rate may be misleading. Always analyze pro-forma NOI (projected after improvements) alongside the in-place cap rate.

Frequently Asked Questions

What is a good cap rate for rental property?

5-8% is the typical target range. Below 5%: premium location with lower income yield but stronger appreciation (gateway cities). 5-7%: balanced risk/return (suburban multifamily, good single-family rentals). 7-10%: higher yield but potentially higher risk (tertiary markets, older properties, higher vacancy). Above 10%: scrutinize carefully — may signal serious property or market issues.

How do I calculate NOI for cap rate?

NOI = Gross Rental Income - Operating Expenses. Operating expenses include: property taxes, insurance, maintenance/repairs, property management, vacancy allowance (5-10%), and capital reserves (5-10%). NOI does NOT include: mortgage payments, income tax, or depreciation. These are financing and tax items, not property operating costs. Accurate expense estimation is critical — underestimating expenses inflates the cap rate.

Is a higher or lower cap rate better?

Higher cap rate = higher income yield but usually higher risk or less desirable location. Lower cap rate = lower income yield but lower risk and better appreciation potential. Neither is inherently "better" — it depends on your investment goals. Income-focused investors prefer 7%+ cap rates. Appreciation-focused investors accept 4-5% in premium markets. Match the cap rate to your strategy.

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

Cap rate assumes an all-cash purchase (NOI ÷ Price). Cash-on-cash return accounts for leverage (Annual Cash Flow After Mortgage ÷ Cash Invested). A 7% cap rate property purchased with 25% down and a 7% mortgage might produce a 4-6% cash-on-cash return (mortgage payments reduce cash flow) or 10-14% (if the cap rate exceeds the mortgage rate, leverage amplifies returns). Both metrics are useful for different analyses.

Do cap rates change with interest rates?

Yes — cap rates and interest rates are correlated but not lockstep. When the Fed raised rates from 0% to 5.5% (2022-2024), cap rates expanded from 4.5-5.5% to 5.5-7% for most property types. Higher rates make debt more expensive, reducing buyer demand and pushing prices down (cap rates up). When rates drop, cap rates typically compress (prices rise). The "spread" between cap rates and the 10-year Treasury yield is the market's risk premium for real estate.
