Core Rental Property Performance Metrics
Successful real estate investors look beyond top-line gross rent to evaluate cash flow durability, debt coverage, and long-term internal rates of return (IRR).
Cap Rate
Measures an asset's unleveraged return regardless of financing terms, providing a baseline comparison across properties.
Cash-on-Cash Return
Measures the actual cash yield generated on your initial out-of-pocket cash outlay (down payment + closing costs + repairs).
Internal Rate of Return (IRR)
The comprehensive annualized rate of return that accounts for rental cash flows, mortgage principal paydown, and terminal capital appreciation upon eventual sale.

Rental Property Calculator — Frequently Asked Questions
Q1 What is Capitalization Rate (Cap Rate) and why is it important? ▾
Cap Rate measures the unleveraged rate of return of a real estate asset, calculated as Net Operating Income (NOI) divided by the purchase price: Cap Rate = NOI / Price. It provides a benchmark to compare the profitability of different properties regardless of individual financing structures.
Q2 How does Cash-on-Cash Return differ from Cap Rate? ▾
Cap Rate evaluates property performance independent of debt, whereas Cash-on-Cash Return (CoC) measures the actual cash yield generated on your initial out-of-pocket cash outlay: CoC = Annual Net Cash Flow / Total Cash Invested (Down Payment + Closing Costs + Repairs).
Q3 What is the "1% Rule" in rental real estate investing? ▾
The 1% Rule is a rapid screening guideline stating that a residential rental property should generate at least 1% of its total acquisition price in gross monthly rent (e.g., $2,000/month rent for a $200,000 purchase) to likely achieve positive net cash flow after operating expenses and mortgage debt service.
Q4 What is Debt Service Coverage Ratio (DSCR)? ▾
DSCR measures a property's ability to cover its annual debt obligations, calculated as NOI / Annual Debt Service. Commercial and investment mortgage lenders typically look for a DSCR of 1.20 to 1.25 or higher.
Q5 How is Internal Rate of Return (IRR) calculated for rental property? ▾
IRR is the annualized discount rate that makes the Net Present Value (NPV) of all cash flows (initial cash invested, ongoing annual rental cash flows, and net proceeds from the eventual sale after paying off remaining debt and commissions) equal to zero.
