Gross Rent Multiplier Calculator

Find a property GRM.

How it is calculated

The gross rent multiplier compares what a property costs with the rent it earns before expenses: GRM = purchase price ÷ annual gross rent. Enter the price and the annual rent in the same currency; the tool divides the two and shows the ratio to two decimals, with no currency or unit. The rent must be above zero. Read the result as the number of years of gross rent needed to equal the price, so a lower GRM means the rent covers the price faster. The ratio ignores taxes, vacancy, maintenance, insurance and financing, so it is a quick screening number for comparing similar properties, not a measure of profit. Typical levels differ between cities and property types.

Worked example

A flat costs 3,000,000 and is rented for 250,000 a year. The calculation is 3,000,000 ÷ 250,000 = 12. The tool shows 12.00: it would take about twelve years of gross rent to equal the purchase price. A second flat priced at 3,000,000 with 300,000 of annual rent would give 10.00, which is the better-looking deal on this one measure.

Common mistakes

  • Entering monthly rent. The formula needs annual rent; a monthly figure makes the GRM twelve times too high. Multiply monthly rent by 12 first.
  • Mixing currencies or including purchase costs inconsistently. Price and rent must use the same currency, and you should decide whether closing costs are in the price.
  • Treating GRM as yield. It is the inverse idea: a lower GRM is better, and 1 ÷ GRM gives the gross yield.
  • Comparing very different properties. A GRM only makes sense against similar properties in a similar market.
  • Ignoring expenses. Because it uses gross rent, a high-maintenance building can look better than it is.

About this calculator

This calculator finds the gross rent multiplier (GRM) — a property's price divided by its gross annual rental income — a quick screening ratio that shows roughly how many years of rent it would take to “pay back” the purchase price, before any expenses.

Real estate investors use it to rapidly compare multiple rental properties side by side; a lower GRM generally suggests a better rental value relative to price. It's not as precise as cap rate since it ignores operating costs, but it's fast enough for a first-pass filter on a list of listings.

    Gross rent multiplier uses the annual rent before vacancies, taxes, insurance, repairs and management, so two properties with the same multiplier can earn very different net income. A lower multiplier means the price is recovered faster on paper, but check the costs before you draw a conclusion. Always use the annual figure; typing monthly rent gives a number twelve times too big. What kind of property are you comparing, flats or shops?
