Capitalized Rent Calculator
Capitalized rent turns a rental income stream into a property value: the present value of the income the property can produce, which is the core of the income approach to real estate appraisal. In its simplest form you divide annual net operating income by a capitalization rate; for a lease with a fixed remaining term, you discount each year’s growing rent back to today instead. This calculator runs both methods, so you can value a perpetual income stream or a finite lease with the same tool. If you need the rate rather than the value, our cap rate calculator works the inverse problem.
Quick Answer
Direct mode: $50,000 of annual NOI ÷ 5% cap rate = $1,000,000 capitalized value. Against a $950,000 asking price that is 5.3% above the ask, so the tool reads it as a potential bargain. Term mode: the same $50,000 growing 2% a year for 10 years, discounted at 7%, has a present value of $380,325.05. Run either mode above.
Key takeaways
- Direct capitalization: value = annual NOI ÷ cap rate; a perpetuity shortcut for stable income.
- Finite-term PV discounts each year’s rent separately, which is the right method for leases with a fixed remaining term.
- The cap rate dominates the answer: small rate moves swing value enormously, so derive it from comparable sales.
- Use NOI, not gross rent, for investment-grade accuracy; gross rent overstates value by ignoring expenses and vacancy.
- The asking-price verdict is an illustrative first-glance signal, never a pricing rule.
Feeding the calculator your numbers
Pick a mode, enter the income figure and the rate, and read the value. Results stay hidden until you click Calculate.
- Pick the valuation method. Direct capitalization values a perpetual stream: stabilized rentals held indefinitely. Finite-term present value prices a lease with years remaining. Switching modes hides the other mode’s fields and clears the result.
- Enter the annual income. In direct mode, enter net operating income, not gross rent (see the NOI rule below). In term mode, enter the lease’s year-one rent. The worked example has $50,000 pre-filled.
- Enter the rate. Direct mode takes the cap rate (5% pre-filled); term mode takes the discount rate (7%), the remaining term in years (10), and the annual growth rate (2%).
- Optionally enter the asking price. In direct mode only, the tool compares its income value against the ask and shows an illustrative verdict band. Leave it blank for a plain valuation.
- Click Calculate value. You get the capitalized value or present value, the breakdown lines, the formula as computed, and Copy/Share buttons.
Invalid inputs are rejected with plain messages: an annual income at or below zero (“Enter annual rent above zero.”), a cap rate at or below zero (“Enter a capitalization rate above zero.”), a discount rate at or below zero, a lease term under one year, and negative growth. Negative values are not silently repaired, so a typo cannot masquerade as a valuation.
Why the cap rate choice decides everything
Direct capitalization is a division, so the value is hypersensitive to the rate. On $50,000 of annual NOI, one point of cap rate moves the value by hundreds of thousands, which is why appraisers derive the rate from recent comparable sales (each comp’s NOI divided by its sale price) rather than picking one.
| Cap rate | Capitalized value | What it implies |
|---|---|---|
| 4% | $1,250,000 | Low risk, high demand, prime asset |
| 5% | $1,000,000 | Typical stabilized property |
| 6% | $833,333 | Moderate risk or secondary market |
| 7% | $714,286 | Higher risk, value-add profile |
| 8% | $625,000 | Distressed or high-vacancy asset |
The Uniform Standards of Professional Appraisal Practice require appraisers to support the rate with market evidence, and guessing it is the single biggest source of error in income valuations. If you already know the price and want the rate instead, our cap rate calculator runs the reverse: NOI ÷ price × 100. That page owns the reverse question; this page owns value from a rate.
Perpetuity or finite term: picking the right mode
Use direct capitalization when the income is effectively perpetual: stabilized rentals held indefinitely, where next year’s income looks like this year’s. The math assumes the income continues forever, which slightly overstates value for wasting assets but is standard for ongoing operations.
Use the finite-term present value when the income has an end date: a 10-year commercial lease, a ground lease with 15 years remaining, or any contract with a fixed term. There the tool discounts each year’s rent, growing at your assumed rate, back at your required return. The two answers differ on purpose: the $1,000,000 direct value assumes income forever, while the $380,325.05 term value prices only ten years of it. Confusing the two is a classic error; a leasehold with a short remaining term is worth far less than the same income capitalized in perpetuity. For screening purchases on income before expenses, pair this with our gross potential rent calculator; for a yield view from the price side, our lease yield calculator derives the yield from income and price.
The NOI rule: rent is not income
The worked example uses $50,000 as net operating income. That distinction is the whole ballgame. Gross rent counts every dollar the tenants pay; NOI subtracts vacancy, maintenance, taxes, insurance and management, but never mortgage payments. Rent equals NOI only if operating expenses are zero, which they never are.
A property grossing $50,000 with $15,000 of expenses has $35,000 of NOI, worth $700,000 at a 5% cap, not $1,000,000. That 30% haircut is the difference between a screen and an investment decision. Enter your NOI in the annual income field whenever you have it; the math is identical, the answer is honest. If you only have gross rent, say so to yourself before trusting the number: the value you get assumes zero expenses. Our buy to rent ratio calculator offers another quick screen from the price side.
| Check run | Inputs | Tool result | Reading |
|---|---|---|---|
| Direct, worked example | $50,000 NOI, 5%, ask $950,000 | $1,000,000.00 | Priced below income value: potential bargain |
| Direct, no ask | $50,000 NOI, 6% | $833,333.33 | Income value calculated |
| Direct, above ask | $50,000 NOI, 5%, ask $1,100,000 | $1,000,000.00 | Priced above income value: caution |
| Direct, near ask | $50,000 NOI, 5%, ask $1,020,000 | $1,000,000.00 | Priced near income value |
| Term, worked example | $50,000, 7%, 10 years, 2% growth | $380,325.05 | Present value of 10-year rent stream |
| Term, flat rent | $40,000, 8%, 15 years, 0% growth | $342,379.15 | Present value of 15-year rent stream |
The verdict bands are the tool’s own construct: more than 5% above the ask reads as a potential bargain, more than 5% below reads as caution, and anything inside the band reads as near income value. Treat them as an illustrative first-glance signal, never a pricing rule: a bargain verdict does not make a property worth buying, and a caution verdict does not make it worthless.
What rival rent calculators get wrong
Most capitalized-rent tools implement only the perpetuity division and present it as the whole subject, leaving leasehold and fixed-term income unpriceable. The gaps break down like this:
- Perpetuity-only rivals (the generic capitalized-rent pages): one formula, one example, usually $120,000 at 6% = $2,000,000. No lease mode, no asking-price check, and several take gross rent without ever mentioning NOI, which quietly overstates every valuation they produce.
- Confusing field layouts (one exact-keyword rival asks for both annual rent and NOI as separate inputs): two income fields for one division invites double-counting. This page asks for one income figure and tells you exactly what it must be.
- Cap rate calculators that run the reverse (Landlord Studio, arvcalc and similar): strong tools, and genuinely useful, but they answer “what rate is this price,” not “what value is this income.” They are the complement to this page, not a substitute, which is why the reverse question is handed to our cap rate calculator above.
- The gap this page fills: both valuation modes in one tool, an NOI-first input with the rent-equals-NOI-only-if-expenses-are-zero rule stated outright, an asking-price verdict that is labelled illustrative, and the cap-rate sensitivity table that explains why the rate input deserves more care than the income input.
Frequently asked questions
The present value of a rental income stream: an estimate of property value derived from the income it produces, the core of the income approach to appraisal.
Direct method: annual NOI ÷ cap rate ($50,000 ÷ 5% = $1,000,000). Finite-term method: discount each year’s growing rent at your required return and sum them ($50,000 growing 2% for 10 years at 7% = $380,325.05).
Net operating income for real decisions: gross rent minus vacancy and operating expenses (excluding mortgage payments). Gross rent equals NOI only if expenses are zero, so it is only a first screen.
It depends on risk and market: 4-5% for prime stabilized assets, 6-8% for higher-risk or secondary-market properties. Derive it from comparable sales, not rules of thumb.
When the income has an end date: a commercial lease with years remaining, a ground lease, or any fixed-term contract. Perpetuity math overvalues wasting income.
Not necessarily. It is the income approach indication of value; market value also reflects comparable sales and replacement cost. Appraisers reconcile all three.
That is the reverse question: cap rate = NOI ÷ price × 100. Our cap rate calculator runs it. This page owns the opposite direction, value from a rate.
