Mortgage
Monthly payment, total cost, amortization, compare two loans.
What it does
Simulates a fixed-rate mortgage with equal monthly payments, like a bank: the monthly payment, the interest you pay over the whole loan, the total repaid, and year by year how much of each payment goes to interest and how much pays off the capital.
How
- The property: price, buying costs (registration duties, notary… type them yourself: they depend on your region and situation), down payment. The loan amount follows.
- Loan A: yearly rate and length. Turn on Compare to set a Loan B (another rate or length) and see the difference.
- Tap a loan’s card to show its chart and its year-by-year table. Export gives the month-by-month schedule as a spreadsheet file.
Monthly rate
In Belgium, the yearly rate becomes a monthly rate by the equivalent method, (1 + rate)^(1/12) − 1: 3 % a year gives 0.2466 % a month. In France, the proportional method is used: rate ÷ 12, 0.25 %. The proportional one gives a slightly higher payment.
Good to know
The payment is rounded to the cent and the last one settles the rest, as banks do. Not included: loan insurance, file fees, mortgage registration costs, variable rates. It’s a simulation to understand and compare, not a bank offer: the bank’s figures (APR) decide.
