Waiting for your data. Fill in all the fields (use 0 if not applicable).

Calculation version: personal@1.0.0. The calculation runs in your browser: we don't send or store the amounts you enter. We only count, without identifying you, that the tool has been used.

How to use it

  1. 1Enter the home price, purchase costs, down payment and mortgage terms.
  2. 2Enter the rent of an equivalent home, how much rents rise and the appreciation you assume.
  3. 3Set the return you'd get investing the money you don't put into the home, and the horizon in years.

How it calculates

  • Buying: wealth = home value × (1 − selling costs) − outstanding debt + what was invested in months when buying was cheaper than renting.
  • Renting: the down payment and purchase costs are invested at the start and, each month, the difference is invested if renting is cheaper.
  • Mortgage payment with the French system; owner costs as a % of the price per year; monthly return equivalent to the annual one entered.

Verifiable example

With a €250,000 home, 10% costs, 20% down payment, a 3% mortgage over 30 years (€843.21/month), 1% annual costs, 2% appreciation, €1,000 rent rising 2% and a 4% return: after 15 years, buying leaves €226,971 of wealth and renting €137,021; buying starts to pay off in year 6.

Limitations

  • Before taxes and without deductions.
  • Appreciation, rent rises and returns are assumptions, not forecasts.
  • It doesn't value the flexibility of renting or the security of owning. It isn't financial advice.
