Rental Yield, Cap Rate, Cash-on-Cash and DSCR Explained

Rental metrics are shortcuts for looking at income, expenses, financing and risk. They are useful only when the assumptions behind them are visible.

Quick answer

Gross yield compares rent with property value before expenses. Net yield or cap rate compares net operating income with property value before financing. Cash-on-cash return compares cash flow with upfront cash. DSCR compares net operating income with debt payments.

The property yield calculator is best for focused metric checks.

  • You want quick rental yield Use it when you want gross yield, net yield or cap rate from rent, value and expenses.
  • You are comparing rent and price It is useful for a first pass before building a full rental cash-flow scenario.
  • You need a simple metric check Use it to understand metric direction, not to decide whether a property is suitable.

Input assumptions explained

These assumptions decide which metric is being measured and how broad it is.

  • Annual rent Gross yield starts with rent before vacancy, management and operating expenses.
  • Property value or purchase price Yield and cap-rate calculations divide income by the value or price assumption entered.
  • Operating expenses Expenses such as insurance, rates, maintenance and management lower net operating income.
  • Vacancy Vacancy reduces collected rent before fixed costs are considered.
  • Upfront cash Cash-on-cash return compares annual cash flow with cash invested, not property value.
  • Debt service DSCR compares net operating income with mortgage or loan payments.

Worked example

If a 600,000 rental earns 600 per week, annual rent is about 31,200. Operating expenses then decide how much income remains before financing.

Property value
600,000
Used as the denominator for gross yield and cap rate.
Rent
600 per week
Annual rent is about 31,200.
Gross yield
About 5.2%
Annual rent divided by property value.
Operating expenses
9,000 per year
Subtracted before net operating income.
Net operating income
22,200 per year
Annual rent minus operating expenses.
Cap rate
About 3.7%
NOI divided by property value, before financing.

Financing can still make monthly cash flow negative even when gross yield looks reasonable.

Result interpretation

Read the result as a scenario based on the assumptions entered, not as a decision rule.

Gross yield

Before expenses

Good for a quick rent-to-price comparison, but too narrow for cash-flow decisions.

Net yield or cap rate

Before financing

Shows income after operating expenses but before loan payments and tax.

Cash-on-cash return

Uses cash invested

Can change sharply when purchase costs, deposit or financing assumptions change.

DSCR

Debt coverage

A DSCR below 1.0 means estimated NOI is lower than debt service in that scenario.

Common mistakes

These are common ways an estimate can become cleaner than the real-world scenario.

  • Calling gross yield cash flow Gross yield does not include expenses, debt payments, vacancy or tax.
  • Mixing cap rate and cash-on-cash return Cap rate uses property value. Cash-on-cash return uses upfront cash invested.
  • Ignoring vacancy and maintenance Both can materially change NOI and every metric based on NOI.
  • Using DSCR as a universal rule DSCR is a coverage ratio. It does not capture every lender rule, local cost or investment risk.

FAQs

What is gross rental yield?

Gross rental yield is annual rent divided by property value or purchase price, before expenses and financing.

Is net yield the same as cap rate?

They are often used similarly: net operating income divided by property value before financing.

Why can cash flow be negative when gross yield looks positive?

Gross yield ignores operating expenses and debt payments. Cash flow includes more of the ownership scenario.

What does DSCR mean?

DSCR means debt service coverage ratio. It compares net operating income with debt payments.

Do these metrics include tax?

No. These guide examples are before tax and do not model local tax treatment.

Methodology and limits

Rental metrics are general before-tax estimates. They are not financial, tax, legal, accounting, mortgage or investment advice, and they do not account for every repair, local rule, tenant outcome or market change.
