Rental Property Calculator

Find out whether a property bought to let with a mortgage pays off: what it costs you each month, when the rent covers the mortgage and all the costs, and from when a sale would leave you in profit.

Past growth is no forecast: a boom of the last years rarely repeats. The default is the inflation target of the Fed (2 % a year).

An estimate for information only, not financial, tax or technical advice. How it is calculated and where the data come from

How the calculator works

A property to let earns in two ways: the rent left over after the mortgage and the costs, and the rise in its value that you collect when you sell. With a mortgage the first is often negative for years, so the question is whether the second makes up for it.

The calculator follows the property month by month: it collects the rent minus the empty months, pays the mortgage, the running costs and the tax, and keeps adding up what is left over or what you top up.

For every year it also works out what you would end up with if you sold then. The first year in which that turns positive is when the investment has paid back all your money, including every monthly top-up.

The default growth of prices and rents is the central bank's inflation target, on purpose a sober assumption. Next to it you see how prices and rents actually grew in your country or city, from official statistics, and can use those figures instead.

Frequently asked questions

What is a good rental yield?

It depends on the market and the interest rates. The gross yield (a year's rent divided by the price) only says how much rent the property brings for its price; what matters is the cash flow after the mortgage and costs. If the net yield is below your mortgage rate, the mortgage costs more than the property earns from rent, and you depend on the price growing.

Why is my monthly cash flow negative?

With a large mortgage the payment, which includes repaying the loan, is often higher than the rent minus the costs. Part of the top-up is not lost: it repays the mortgage and you get it back on the sale. The calculator counts both, which is why it shows when a sale would leave you in profit.

Which price growth should I enter?

The default is the central bank's inflation target, that is prices keeping pace with inflation. Below the field you can see the official history of your country or city; the last fifteen years were exceptional in many places, so try several values and see how much the result depends on it.

Does the calculator include taxes?

Only as one effective rate on the yearly profit from letting, which you enter yourself (0 by default). Tax rules for landlords differ by country, by person and by how you own the property, so for the real figure ask a tax adviser.

What are empty months?

Months when the property earns no rent: between tenants, during repairs or when a tenant doesn't pay. Even a good property is rarely let twelve months a year for decades, so the advanced mode counts one empty month a year by default.

Is buying to let better than investing the money elsewhere?

The calculator looks only at the property. Its yearly return on your own money gives you a figure to compare with other investments yourself, keeping in mind that a property takes time to manage and can't be sold in a day.

How it is calculated and where the data come from

How the result is calculated

  1. The mortgage is the purchase price minus your deposit, repaid month by month with an annuity; in the advanced mode the rate changes after the fixed period.
  2. The rent is collected every month, lowered by the empty months and raised once a year by the rent growth. The running costs rise once a year by the cost growth; the management fee is a share of the rent collected.
  3. The tax is the rate entered times the yearly profit from letting (rent minus costs and mortgage interest) when it is positive; it is paid at the end of each year.
  4. The property's value grows smoothly by the price growth. The result of a sale in any year is the value minus the selling costs and the remaining mortgage, plus all the cash flow so far, minus the money you put in upfront.
  5. The yearly return is the internal rate of return of your own money: the upfront payment, each year's cash flow and the proceeds of the sale.

Assumptions and limits

  • All amounts are nominal, not adjusted for inflation.
  • Taxes are one effective rate on the rental profit; depreciation, allowances, carried-forward losses, the tax on the sale and subsidies are not included.
  • Prices and rents grow evenly; real markets go up and down, and a property can be worth less when you need to sell.
  • The history of a place is the average of an official index for the whole city or region; a particular property, street or kind of flat can differ a lot.

The price, rent and costs are round examples, not statistics. The growth starts at the central bank's inflation target; the starting mortgage rate comes from official statistics of new loans in the country.

Data sources and the period they hold for

Every number a calculator starts with or computes from comes from one of the sources below. Series names are given as the publisher names them. Each row shows the period the data refer to and, where we record it, the day we downloaded them. Official data can be months old when they are published, so check the current figure before you decide.

Official
Published by a central bank, a statistical office, the European Union or another public body.
Research or industry data
A dataset of a university, an index provider, an industry association or a data vendor.
Reported
A figure of an official body that we know only from the press and did not check in the primary source. Treat it as approximate.
Example
A round number of ours, not a statistic. Replace it with your own.
