Quick answer
Quick answer: cap rate equals NOI divided by property value
Use cap rate to compare unlevered property yield. It does not include mortgage terms, so pair it with cash-on-cash return for financed deals.

How to use this calculator: Enter your financial information in the fields above. Results update automatically as you type. All calculations are performed locally in your browser - we never store or share your personal financial data.
How the Math Works
- The calculator converts your inputs into monthly and annual totals, then applies category-specific formulas for Cap Rate.
- Intermediate values are rounded for display, but calculations preserve precision until final totals are shown.
- Scenario outputs compare baseline values against changed inputs so you can estimate tradeoffs quickly.
Assumptions
- Inputs are treated as stable over the time period you select.
- Rates and costs are assumed to remain constant unless you model a change manually.
- Results are planning estimates, not a lender quote, tax filing output, or legal advice.
Worked Examples
Conservative scenario
Increase key costs by 10% and reduce expected upside by 10%.
If the result still works, your plan likely has a practical safety margin.
Optimized scenario
Adjust one or two controllable levers (rate, payment, timeline, or contribution).
Compare whether the gain is meaningful enough to justify the extra effort.
When This Estimate Breaks
- Your actual numbers can differ when taxes, fees, policy rules, or market pricing change.
- Large life changes (income shifts, relocation, new debt, job changes) can invalidate assumptions quickly.
- Use this estimate with real quotes/statements before making a final financial decision.
Methodology and Editorial Review
- The model computes a baseline from your entered inputs, then recalculates results for each scenario change.
- Displayed values are rounded for readability while internal calculations keep precision until output formatting.
- Editorial review validates formula consistency, assumptions, and user-facing interpretation text.

How Cap Rate Calculator Works
Calculate the capitalization rate to evaluate and compare rental property investments. Cap rate measures the return you'd earn if you paid all cash, making it useful for comparing properties regardless of financing.
1
Calculate Net Operating Income (NOI)
Start with annual gross rental income. Subtract vacancy loss, property taxes, insurance, maintenance, property management, and other operating expenses. Do NOT subtract mortgage payments.
2
Determine Property Value
Use the purchase price for a property you're evaluating, or current market value for properties you own.
3
Calculate Cap Rate
Cap Rate = NOI ÷ Property Value × 100. A $100,000 NOI on a $1,000,000 property = 10% cap rate.
4
Compare to Market
Research typical cap rates for your market and property type. Compare your deal to market averages.
5
Understand the Trade-offs
Higher cap rates mean higher returns but often indicate higher risk (worse location, older building, more management intensive).
Key Factors Considered:
- ✓Gross rental income
- ✓Vacancy and collection loss
- ✓Operating expenses (taxes, insurance, maintenance)
- ✓Property management costs
- ✓Property purchase price or value
- ✓Market cap rates for comparison
- ✓Property class (A, B, C, D)
- ✓Location quality and trends
Why Calculate Cap Rate
- Compare properties regardless of financing
- Quickly evaluate investment opportunities
- Understand market-rate returns for an area
- Identify overpriced or underpriced properties
- Estimate property value from NOI
- Communicate value with other investors
- Screen deals quickly before deep analysis
- Set asking price when selling
Key Terms to Know
- Capitalization Rate (Cap Rate)
- NOI divided by property value. Represents the return if you paid all cash. Useful for comparing properties regardless of financing. Range: 4-12% typically.
- Net Operating Income (NOI)
- Annual income minus operating expenses, NOT including mortgage. NOI = Gross Income - Vacancy - Operating Expenses. The numerator in cap rate.
- Going-in Cap Rate
- Cap rate at purchase based on current NOI. What you're "buying at." Lower cap rate = paying more per dollar of income.
- Exit Cap Rate
- Projected cap rate when selling. If exit cap rate > going-in rate, property value decreases (bad). Conservative investors assume exit cap rate rises.
- Cap Rate Compression
- When cap rates decrease (prices rise relative to rents). Common in hot markets. Low cap rates = expensive market.
Pro Tips
- →Cap rate range: 4-6% in expensive/desirable markets, 8-12% in riskier areas
- →Higher cap rate = higher return but usually higher risk
- →Class A properties (new, prime location) have lowest cap rates (4-6%)
- →Class C/D properties (older, worse areas) have highest cap rates (8-12%)
- →Cap rate doesn't account for appreciation potential or financing benefits
- →Value = NOI ÷ Cap Rate. Use to estimate purchase price or value from income.
- →Cap rate is a quick screening tool - do full analysis before buying
- →Don't compare cap rates across different markets or property types
- →Low cap rate market may still be good if appreciation is strong
- →Cap rate ignores capex - a property needing $50k roof has lower real return
📊 Quick Answer: Cap Rate
📈 Formula
Cap Rate = NOI ÷ Property Value × 100
🏠 Typical Ranges
Class A: 4-6% | Class B: 6-8% | Class C: 8-12%
💡 Rule of Thumb
Higher cap rate = higher return but higher risk
📊 Cap Rate by Property Type Table
| Property Type | Low Cap Rate | High Cap Rate | Risk Level |
|---|---|---|---|
| Class A (Premium) | 4% | 6% | Low |
| Class B (Standard) | 6% | 8% | Medium |
| Class C (Value-Add) | 8% | 10% | Medium-High |
| Class D (High Risk) | 10% | 12%+ | High |
* Approximate ranges. Cap rates vary by market, location, and economic conditions.
⚠️ Common Cap Rate Mistakes
1. Including mortgage payments in NOI
NOI only includes operating expenses. Never include debt payments.
2. Comparing cap rates across different markets
A 6% in NYC is not the same as 6% in a rural market. Compare within the same market.
3. Ignoring capital expenditures (CapEx)
A building needing a new roof has lower real return than its cap rate indicates.
4. Using only cap rate for decisions
Cap rate is a screening tool. Do full analysis before buying.

Frequently Asked Questions - Cap-rate
- What is cap rate in real estate?
Cap rate (capitalization rate) is NOI divided by property value. It measures annual return on real estate investment without considering financing. Example: $10,000 NOI ÷ $200,000 value = 5% cap rate.
- What is a good cap rate?
Depends on market and risk. Class A properties: 4-6%. Class B: 6-8%. Class C: 8-12%. Expensive markets have lower cap rates. Higher cap rate = higher risk but higher potential return.
- How do you calculate NOI for cap rate?
NOI = Gross income - operating expenses. Include: rent, minus vacancy, minus taxes, insurance, maintenance, management. Do NOT include mortgage payments, depreciation, or income taxes.
- Is higher or lower cap rate better?
Depends on your strategy. Higher cap rate = higher return but higher risk (declining neighborhoods, more maintenance). Lower cap rate = lower risk but lower return (prime areas, stable).
- How to use cap rate to compare properties?
Cap rate allows comparing properties of different prices and markets. But also consider: area quality, appreciation potential, management ease, and local market trends.
- What are cap rate limitations?
Cap rate doesn't consider: financing, appreciation, capital improvements, tax benefits, or future changes in income/expenses. It's just a snapshot of current moment, not future projections.
