Cap Rate Calculator 2026 — Real Estate Capitalization Rate & NOI

What Is a Cap Rate in Real Estate?

The capitalization rate — universally shortened to "cap rate" — is the single most important metric in income-producing real estate. It quantifies the relationship between a property's annual Net Operating Income (NOI) and its current market value, expressed as a percentage. Unlike gross rent or price-per-unit, cap rate strips away all the noise and answers one direct question: how much does this property earn relative to what it costs?

Cap rate is entirely financing-neutral. It assumes an all-cash purchase — no mortgage, no debt service. This makes it the universal language of real estate comparison. A broker who says a property "trades at a 6 cap" means buyers pay roughly 16.7× the annual NOI for it (100 ÷ 6 = 16.7). That multiple encodes everything: location quality, tenant stability, market demand, and risk perception — all in a single number.

For residential buy-and-hold investors, cap rate is typically the first number calculated when screening a deal. It won't tell you everything — financing terms, appreciation potential, and local rent growth all matter — but it gives you an instant, consistent basis for comparing any two properties, anywhere, regardless of size or price.

The Cap Rate Formula: Step by Step

The cap rate formula requires just two inputs, but both must be calculated carefully. Optimistic assumptions at either step — inflated income or understated expenses — will produce a misleadingly high cap rate and a bad investment decision.

Cap Rate = Net Operating Income (NOI) ÷ Current Market Value × 100

Step 1 — Gross Income: Total scheduled rent + other income (parking, laundry, storage)
Step 2 — Effective Gross Income (EGI): Gross Income − Vacancy & Credit Loss
Step 3 — NOI: EGI − All Operating Expenses (taxes, insurance, mgmt, maintenance, CapEx)
Step 4 — Cap Rate: NOI ÷ Property Value × 100

Worked Example

Consider a duplex listed at $420,000in a mid-sized US city. Each unit rents for $1,400/month, and there's a coin-operated laundry generating $800/year.

Gross Rental Income: $1,400 × 2 × 12 = $33,600/year
Vacancy Loss (6%): −$2,016
Other Income: +$800
Effective Gross Income: $32,384
Operating Expenses: Property tax $4,200 + Insurance $1,600 + Management (9%) $2,915 + Maintenance $2,000 + CapEx Reserve $1,500 = $12,215
NOI: $32,384 − $12,215 = $20,169
Cap Rate: $20,169 ÷ $420,000 × 100 = 4.80%

At 4.80%, this deal sits at the lower end of the 2026 single-family/small multifamily benchmark range of 3.5%–6.0%. Whether that's acceptable depends on the market's appreciation trajectory, local vacancy trends, and your investment thesis. Use the calculator above to stress-test inputs — try raising vacancy to 10% or adding a $3,000 roof reserve and see how quickly the cap rate shifts.

What Is a Good Cap Rate in 2026?

The honest answer is: it depends on what you're buying and where. A 4.5% cap rate on a Class A multifamily building in a supply-constrained coastal market may represent exceptional value, while a 4.5% cap rate on a rural retail strip with a single anchor tenant could be financially catastrophic. Context is everything.

That said, here are practical 2026 benchmarks broken down by asset class:

Property Type	2026 Cap Rate Range	Risk Level	Key Drivers
Multifamily (5+ units)	4.5% – 6.5%	Low–Moderate	Demand stability, low vacancy in urban cores
Single-Family Rental	3.5% – 6.0%	Low	Appreciation-driven; lower yields common
Industrial / Warehouse	4.0% – 6.5%	Low–Moderate	E-commerce tailwinds; long-term NNN leases
Retail / Strip Mall	5.0% – 8.0%	Moderate–High	Tenant mix quality; anchor stability critical
Office	5.5% – 8.5%	High	Remote work pressure; market-by-market risk
Self Storage	5.0% – 7.5%	Moderate	Recession-resistant; low operating costs
Mobile Home Park	5.5% – 8.0%	Moderate	Affordable housing demand; low supply growth
Hospitality / Hotel	6.5% – 10.0%	High	RevPAR sensitivity; operational complexity

A higher cap rate is not automatically better. Properties trading above 9%–10% almost always carry an elevated reason: concentrated tenant risk, deferred maintenance, an economically challenged location, or limited near-term appreciation. A 4.5% cap in a high-barrier-to-entry market often delivers stronger total returns over a 10-year hold than an 8% cap in a stagnant secondary market.

5 Factors That Drive Cap Rates

1. Location and Market Strength

Nothing compresses cap rates faster than strong demand. Investors accept lower returns in markets where vacancy is structurally low, population is growing, and future rent increases are reliable. Conversely, markets with economic uncertainty, high crime, or declining population demand higher cap rates to compensate for the additional risk. The same physical building in San Jose vs. a rural Midwest town might trade at a 4.5% vs. 8.0% cap rate for this reason alone.

2. Property Type and Income Reliability

The more predictable and durable the income stream, the lower the cap rate investors accept. Triple-net (NNN) leased industrial buildings with 10-year corporate tenants trade at very compressed rates because the income is near-certain. By contrast, hospitality properties — where occupancy can swing 30 percentage points in a recession — demand premium returns to justify the volatility.

3. Property Condition and Capital Requirements

A well-maintained, recently-renovated property has lower near-term capital requirements and attracts better tenants. That predictability reduces risk and suppresses cap rates. Older or distressed properties are priced with higher cap rates to reflect the likely capital expenditure pipeline — roof replacement, HVAC, electrical upgrades — that will erode net cash flow in the coming years. Always model CapEx reserves honestly; seller pro formas frequently omit them.

4. Rental Strategy (Long-Term vs. Short-Term)

Short-term rental (STR) properties such as Airbnb-style vacation rentals typically generate significantly higher gross income than equivalent long-term rentals — but the operational complexity is proportionately higher. Dynamic pricing, cleaning costs, platform fees, and seasonal vacancy all reduce the net margin. STR cap rates should reflect that management burden. If you're comparing an STR opportunity to a long-term rental, make sure your expense assumptions capture the full operating cost.

5. Prevailing Interest Rates

Cap rates and interest rates are closely correlated over long periods. Historically, cap rates tend to trade 150–300 basis points above the 10-year Treasury yield. During the ultra-low-rate environment of 2020–2022, cap rates compressed dramatically as capital flooded into real estate. As rates rose through 2023–2026, cap rates expanded. In 2026, with 10-year Treasuries in the 4.0%–4.5% range, real estate cap rates have stabilized at levels that again offer meaningful spreads over risk-free alternatives — making the income math more straightforward than it was two years ago.

Cap Rate Limitations

Cap rate is an essential starting point — but experienced investors never use it as the only metric. Understanding what it does not capture is just as important as understanding what it does.

It ignores financing entirely. A property with a 6% cap rate financed at 7% is cash-flow negative from day one. Always pair cap rate analysis with cash-on-cash return to understand what your debt structure does to actual returns.
It is a snapshot, not a projection. Cap rate measures current income against current value. It tells you nothing about rent growth potential, near-term capital requirements, or whether the current tenant roll is expiring. A 7% cap today can easily become a 4% cap in two years if rents fall or a major tenant leaves.
Garbage in, garbage out. Cap rates are only as reliable as the expense data behind them. Sellers routinely present pro forma NOI figures that exclude CapEx reserves, use below-market management fees (or none at all), and apply zero vacancy. Run the numbers with your own conservative assumptions, not the seller's.
Cross-market comparisons are misleading. A 7% cap rate in Phoenix reflects entirely different market dynamics than a 7% cap rate in Detroit. Always benchmark against comparable properties in the same submarket, not national averages.
Not suitable for all deal types. Fix-and-flip projects, ground-up development, and repositioning plays don't have stable current NOI to anchor a cap rate. Use IRR, profit margin, or equity multiple for those deal types instead.

Cap Rate vs. Other Key Metrics

Cap Rate vs. Cash-on-Cash Return

Cap rate and cash-on-cash return are often confused but answer very different questions. Cap rate is property-level and financing-neutral — it tells you how productive the asset itself is. Cash-on-cash return is investor-level — it tells you what your equity earns after the mortgage is paid. If your debt costs less than the cap rate (positive leverage), cash-on-cash will exceed the cap rate. If your debt costs more (negative leverage), cash-on-cash will lag. Both numbers should always be calculated when financing is involved.

Cap Rate vs. Gross Rent Multiplier (GRM)

The Gross Rent Multiplier (GRM = Property Price ÷ Annual Gross Rent) is faster to calculate — you don't need expense data — which makes it a useful first screen. A property with a GRM of 10× generates annual gross rents of one-tenth its price. But because GRM ignores all operating expenses, two properties with identical GRMs can have dramatically different cap rates if their tax bills, management costs, or CapEx profiles diverge. GRM is a quick filter; cap rate is the actual decision tool.

Cap Rate vs. DSCR

The Debt Service Coverage Ratio (DSCR = NOI ÷ Annual Debt Service) is critical for financed acquisitions. Most lenders require a minimum DSCR of 1.20–1.25 before approving a loan — meaning the property's NOI must cover debt payments by at least 20–25%. A property can have an attractive cap rate but still fail DSCR underwriting if the loan amount is too large or the interest rate is too high. Always check DSCR alongside cap rate when modeling a leveraged purchase.

Cap Rate vs. Total Return (ROI)

Cap rate measures only current income yield. Total return (or ROI) adds appreciation and principal paydown to the picture. A property with a modest 4.5% cap rate in a market growing at 5% annually may deliver a 9–10% total return over a 5-year hold — far outpacing a static 7% cap rate property in a flat market. For long-hold strategies, model total return rather than relying on cap rate alone.

How to Use This Cap Rate Calculator

Enter Purchase Price or Market Value

For deals you're evaluating, use the asking price. For properties you already own, use today's estimated market value — not your original purchase price. Dividing by what you paid tells you historical yield; dividing by today's value tells you current market performance.

Select Property Type

This determines which 2026 benchmark range appears on the gauge and comparison table. You can also click any card in the benchmarks panel to switch property types and instantly see where your deal sits relative to market norms for that category.

Enter Realistic Gross Income

Use current market rents — not pro forma aspirational rents. Check Zillow Rentals, Apartments.com, or CoStar for comparable leases. Set a vacancy rate that reflects the submarket: 5%–7% is typical for stable multifamily; 10%–15% is reasonable for retail or office in uncertain markets.

Enter All Operating Expenses

This is the step most investors get wrong. Include property tax at the post-purchase reassessed value (not the current owner's bill), management fees even if self-managing, and a realistic CapEx reserve (typically 5%–10% of gross rent). Sellers' pro formas routinely exclude these to inflate NOI. Don't let them inflate yours.

Review the NOI Waterfall

The waterfall shows exactly how gross income flows to NOI, your expense ratio, and the implied fair value at current market cap rates. If the implied fair value is significantly below the asking price, the seller is pricing in future rent growth that may or may not materialize.

Toggle Cash-on-Cash Return

Enable the financing section and enter your down payment, closing costs, and total annual mortgage payments. This bridges the gap between the property-level cap rate and your actual investor return once debt service is accounted for.

Frequently Asked Questions

A capitalization rate (cap rate) is the ratio of a property's Net Operating Income (NOI) to its current market value, expressed as a percentage. It represents the annual return a property generates as if purchased entirely with cash — no mortgage. Cap Rate = NOI ÷ Property Value × 100. A $300,000 property generating $21,000 in NOI has a 7% cap rate. It is the foundational metric for comparing income-producing properties on equal footing regardless of financing.

No — mortgage payments (debt service) are explicitly excluded from cap rate calculations. Net Operating Income is always calculated before debt service. This is by design: keeping financing out of the formula lets you compare any two properties on the same basis regardless of how each is financed. If you want to factor your specific loan terms into the analysis, cash-on-cash return is the appropriate metric. You can calculate it using the financing toggle in this calculator.

For residential rentals, most investors target a cap rate between 5% and 10%, but the right number depends entirely on your market, property type, and risk tolerance. In high-demand urban markets, 4%–6% is typical and acceptable because demand is stable, appreciation is reliable, and vacancy is structurally low. In secondary markets or with higher-risk properties, investors want 7%–9%+ to justify the additional uncertainty. A high cap rate is not automatically good — properties trading above 9%–10% usually carry a specific reason: deferred maintenance, tenant concentration risk, or limited appreciation potential.

A 7% cap rate means the property generates Net Operating Income equal to 7% of its current market value each year — before any debt payments. On a $400,000 property, that's $28,000 in annual NOI. It also implies a payback period of roughly 14.3 years on an all-cash purchase (100 ÷ 7 = 14.3), though this doesn't account for rent growth, capital expenditures, or proceeds from an eventual sale. In most US markets in 2026, a 7% cap rate sits at the higher end of residential and toward the middle of commercial benchmarks.

Net Operating Income (NOI) is the annual income a property generates after subtracting all operating expenses — but before mortgage payments, income taxes, and depreciation. NOI = Effective Gross Income (gross rent minus vacancy, plus other income) minus operating expenses (property tax, insurance, management fees, maintenance, CapEx reserves, utilities, HOA). Mortgage principal and interest are never included. NOI is the numerator in the cap rate formula and the foundation of virtually all commercial real estate valuation.

Yes — this is broadly how appraisers value income-producing properties using the income approach. If you know a property's NOI and you know the market cap rate for comparable assets in that submarket, you can calculate implied value: Implied Value = NOI ÷ Market Cap Rate. For example, a property with $25,000 in annual NOI in a market where similar assets trade at a 6.25% cap rate has an implied value of $400,000 ($25,000 ÷ 0.0625). The Implied Fair Value shown in our NOI waterfall uses this approach, dividing your calculated NOI by the midpoint of the market benchmark range for your selected property type.

Cap rate is a property-level, financing-neutral metric. Cash-on-cash return is an investor-level metric that measures annual pre-tax cash flow as a percentage of the actual cash invested (down payment plus closing costs). If you buy a property all-cash, cap rate and cash-on-cash return are equal (before taxes). When you add financing, they diverge: if your mortgage rate is below the cap rate (positive leverage), cash-on-cash exceeds the cap rate. If your mortgage rate is above the cap rate (negative leverage), cash-on-cash will be lower — meaning debt is actually reducing your returns. Both metrics should always be calculated for financed purchases.

Use your actual NOI from the trailing 12 months — real income minus real operating expenses — and divide by the property's current market value, not your original purchase price. Your purchase price reflects what the market looked like when you bought; today's value reflects what the property would fetch now. Using current value gives you a much more accurate picture of how the asset is performing relative to the current market. If you're unsure of the current value, look at recent comparable sales in your submarket or request a broker opinion of value.

Cap rate works best for stabilized rental properties with consistent income history. It breaks down in several scenarios: (1) Fix-and-flip projects — use profit margin and ROI instead. (2) Ground-up development — use IRR and equity multiple over the project timeline. (3) Properties being repositioned or with significant vacancy — current NOI doesn't reflect stabilized performance, so a pro forma cap rate at stabilization is more relevant. (4) Properties with long-term fixed leases well above or below market — the current NOI may not reflect economic reality once leases roll. In all these cases, cap rate remains a useful reference point but should be paired with deal-specific metrics.
