Cap Rate Calculator: Complete Guide 2026
A cap rate answers one question before anything else: what percentage of a property’s purchase price comes back as annual net operating income? For Las Vegas investors evaluating rentals in Henderson, North Las Vegas, or Summerlin, that single number separates properties worth pursuing from those that only look good on paper.
This guide walks through the cap rate formula step by step, builds a real NOI example using Las Vegas figures, and explains what cap rate benchmarks mean across different property types and neighborhoods in 2026.
Key Takeaways
- Cap rate = Net Operating Income divided by Property Value, expressed as a percentage
- Las Vegas single-family rentals typically yield 4.5-7% cap rates in 2026, depending on neighborhood and property condition
- Cap rate excludes mortgage payments, making it a financing-neutral property metric
- ATTOM Data reported average gross rental yields of approximately 7.5% nationally for SFR properties in 2025, with net cap rates running 1.5-2 points lower after vacancy and operating costs
- Always pair cap rate with cash-on-cash return to understand actual returns on invested capital
What Is Cap Rate and Why Does It Matter for Las Vegas Investors?
Cap rate (capitalization rate) is net operating income divided by property value, expressed as a percentage. It is financing-neutral: a $450,000 Las Vegas rental earning $22,500 in annual NOI has a 5% cap rate whether you paid cash or took out a mortgage. ATTOM Data’s 2025 Home Sales Report found gross SFR rental yields averaged 7.5% nationally, with Sun Belt markets like Las Vegas running lower due to strong price appreciation.
Full definition and history of the metric is in the what is cap rate guide.
Cap rates move inversely to property values. When prices rise faster than rents, cap rates compress. When rents grow faster than prices, cap rates expand. Las Vegas saw sustained cap rate compression from 2020 through 2023 as median home prices surged past $450,000, then gradual stabilization in 2024-2025 as appreciation slowed and rental rates continued modest upward movement.
Source Note: IRS Publication 527 (Residential Rental Property) defines allowable operating expenses as property taxes, insurance premiums, management fees, repairs, and utilities paid by the owner. Mortgage principal and interest are explicitly excluded from operating expenses under this framework, which is why cap rate calculations omit financing costs entirely. This makes cap rate a property-level profitability measure, not an investor-level one. Understanding what counts as an operating expense versus a financing cost is the most common source of calculation errors for first-time rental investors.
How to Calculate Cap Rate Step by Step
The cap rate formula uses two inputs: net operating income (NOI) and property value. NOI equals annual gross rental income minus every operating expense including vacancy, taxes, insurance, management, and maintenance. Calculating it accurately requires four steps, and precision on the expense side is where most investors make errors. The Las Vegas housing market guide provides current rental benchmarks for estimating gross income by neighborhood.
Step 1: Determine Annual Gross Rental Income
Start with realistic market rent based on current comparables. A 3-bedroom, 2-bath home in Henderson renting for $2,200 per month generates $26,400 annually.
Step 2: Calculate All Operating Expenses (Including Vacancy)
| Expense Category | Annual Amount |
|---|---|
| Vacancy allowance (5%) | $1,320 |
| Property taxes | $2,800 |
| Landlord insurance | $1,200 |
| Property management (10%) | $2,640 |
| Maintenance and repairs | $2,000 |
| Landscaping and pool service | $960 |
| Total Operating Expenses | $10,920 |
Step 3: Compute Net Operating Income
NOI = Gross Income - Total Operating Expenses $26,400 - $10,920 = $15,480
Step 4: Apply the Cap Rate Formula
For a purchase price of $350,000: Cap Rate = ($15,480 / $350,000) x 100 = 4.4%
What Is a Good Cap Rate in Las Vegas in 2026?
A good Las Vegas cap rate in 2026 sits between 5% and 7% for most single-family rentals, with the right target depending on neighborhood, property age, and investment strategy. According to GLVAR market data, the Las Vegas valley median existing home price in early 2026 remained above $460,000, keeping cap rates compressed in premium corridors like Summerlin (4-5%) and higher in value-add areas like North Las Vegas (6-7%).
Source Note: ATTOM’s 2025 U.S. Home Sales Report analyzed rental yields across 572 counties and found average annual gross rental yields on 3-bedroom single-family homes at approximately 7.5% nationally. Nevada’s Clark County yields were compressed relative to the national median because of strong home price appreciation over the prior three years. Net cap rates, after subtracting vacancy and operating costs, typically run 1.5 to 2.5 percentage points below gross yield figures.
Use these benchmarks as a starting framework:
- Below 4%: Only appropriate with extraordinary appreciation potential, strong value-add upside, or a development play. Negative or break-even cash flow is likely.
- 4-5.5%: Typical for premium Las Vegas neighborhoods. Lower current yield, historically stronger long-term appreciation.
- 5.5-7%: The target range for most Las Vegas buy-and-hold investors. Solid income with manageable risk.
- 7% and above: Higher income yield, usually in older properties or emerging areas. Scrutinize deferred maintenance and tenant quality carefully before committing.
Cap Rate vs. Cash-on-Cash Return: Which Metric Matters More?
Cap rate treats a property as if purchased with all cash, while cash-on-cash return measures your actual return on dollars invested after debt service. For a $450,000 property with 25% down, a 5.5% cap rate often translates to an 8-10% cash-on-cash return through leverage. Both metrics are necessary together, because cap rate alone tells you nothing about what your money actually earns.
See the complete cash-on-cash return guide and cash flow fundamentals guide for detailed walkthroughs. The gross rent multiplier guide covers a third quick-screen metric that pairs well with cap rate during initial property evaluation.
| Metric | Includes Financing? | Best Used For |
|---|---|---|
| Cap Rate | No | Comparing properties on equal footing |
| Cash-on-Cash Return | Yes | Evaluating actual annual yield on your down payment |
| Gross Rent Multiplier | No | Fast preliminary screening before full NOI analysis |
Common Cap Rate Calculator Mistakes
Most cap rate errors inflate NOI by understating expenses, turning a marginal Las Vegas property into a paper winner. Desert-climate properties carry costs that investors from other markets routinely miss: extreme summer AC bills, pool service, and desert landscaping. Catching these errors before you close is significantly easier than discovering them in month three of ownership.
1. Using listing price instead of appraised value. Cap rate uses what you actually pay. If comparables support $420,000 but the listing is $450,000, calculate at $420,000 to understand true return potential.
2. Skipping vacancy. Every rental turns over. Budget 5-8% annually. A 5% vacancy on $2,200 rent is $1,320 per year. Ignoring it overstates NOI by that amount.
3. Omitting desert-specific expenses. Las Vegas properties have higher-than-average costs for HVAC (especially June through September), pool maintenance ($80-150/mo), and desert landscaping. Budget $1,200-$2,400/year more than you would in a temperate market.
4. Including mortgage payments. Debt service is a financing cost, not an operating expense. Cap rate must exclude it to remain property-level and financing-neutral.
5. Not modeling management fees. Even self-managing landlords should include 8-12% management fees in their NOI calculation. It represents the true cost of that activity, and most investors eventually hire professional managers. Current Las Vegas property management fee structures run 8-12% of gross collected rent plus leasing fees.
Using Cap Rate to Compare Las Vegas Investment Properties
Cap rate lets you compare the income efficiency of properties across Las Vegas neighborhoods on equal footing, regardless of price or size. According to the National Association of Realtors, expected rental income is the primary evaluation criterion for investment property buyers, making NOI-based metrics central to every purchase decision. Run cap rate on each candidate property, then evaluate whether the premium or discount reflects justified differences in neighborhood trajectory and property quality.
The chart below shows the annual NOI a $400,000 Las Vegas property must produce to hit each cap rate threshold.
For investors screening multiple Las Vegas properties simultaneously, the Las Vegas rental investment guide covers how to use cap rate alongside cash-on-cash and GRM in a three-step screening workflow. The rental investment complete guide addresses how cap rate targets shift as you move from a single property to a multi-property portfolio strategy. Read more in our related guide: 1031 exchange.
Frequently Asked Questions
What is a good cap rate in Las Vegas in 2026?
For Las Vegas single-family rentals, a cap rate between 5.5% and 6.5% is a solid target in 2026. Summerlin and premium Henderson properties typically land in the 4-5.5% range due to higher prices and appreciation history. North Las Vegas and value-add opportunities can reach 6.5-7.5%. Multi-family properties in the metro area generally range from 5.5-7%.
Does cap rate include the mortgage payment?
No. Cap rate uses the full property value in the denominator and excludes mortgage payments from operating expenses. It measures a property’s income efficiency independent of how you financed it. Your leveraged returns are captured by cash-on-cash return, which accounts for your actual down payment and monthly debt service.
How often should I recalculate cap rate on a property I own?
Recalculate at least annually. Property values shift with market conditions, and NOI changes as rents adjust and expense categories evolve. A property purchased at a 5.5% cap rate in 2022 might reflect a 4.8% cap rate today if values have risen faster than rents, or a 6.2% cap rate if you have raised rents and controlled expenses.
What is the difference between cap rate and gross rent multiplier?
Cap rate uses net operating income; GRM uses gross rent before any expenses are deducted. GRM is faster to calculate and useful for a first-pass screen, but it ignores vacancy and operating costs, making it less accurate. Cap rate is the more reliable comparison tool once you have full expense data. See the gross rent multiplier guide for a detailed comparison.
How does Nevada’s tax environment affect cap rates?
Nevada has no state income tax, which improves after-tax cash flow compared to high-tax states but does not directly affect the cap rate formula. Nevada’s property tax rates are also lower than California’s, which reduces the operating expense total and therefore increases NOI. A Las Vegas property at a given purchase price often produces a better cap rate than an equivalent California property for this reason alone.
