What Capitalization Rate Tells You About a Property
概要
The capitalization rate (cap rate) measures a real-estate investment's unleveraged annual return: net operating income divided by the property's market value. It lets you compare very different properties on a like-for-like basis and gauge whether an asking price is reasonable. This calculator computes the cap rate instantly from two inputs, entirely in your browser.
使い方（ステップ）
- 1
Enter the net operating income
Annual rent collected minus annual operating costs (tax, insurance, maintenance, management) — excluding the mortgage.
- 2
Enter the market value
The current price or appraised value of the property.
- 3
Read the cap rate
Compare it against typical rates for similar properties in the same market.
仕組み
Cap rate = (Net Operating Income ÷ Current Market Value) × 100. Net operating income (NOI) is annual rental income minus operating expenses — but not mortgage payments, which is why cap rate reflects the property itself rather than how you finance it. A higher cap rate means more income relative to price (often higher risk or a softer location); a lower cap rate usually signals a premium, lower-risk market.
こんなときに使う
Comparing two rental properties in different neighborhoods. Judging whether an asking price matches the income it produces. Tracking how a market's typical cap rates shift over time.
よくある質問
It depends on the market and risk tolerance. Many investors target 4–10%; lower rates suit prime, stable locations, while higher rates compensate for more risk or weaker areas.
