How much mortgage can I afford
Two things limit you: what you can pay each month and what you have saved. We tell you which one is binding, because that decides what to do about it.

What we assume
- The debt ratio defaults to 35% of net income, including any other loans you are paying.
- Financing defaults to 80% of the price, so you need the other 20% plus the purchase costs in savings.
- Purchase costs default to 10% of the price: transfer tax, notary, registry and fees.
- This is an indicative estimate. Every lender has its own criteria, values the property itself, and looks at your job security and your whole profile.
How it is calculated
Two independent ceilings are worked out and the lower one wins.
The income ceiling
Your maximum payment is the debt ratio applied to your income, minus what you already pay on other loans. Turning that payment back into a loan amount and grossing it up by the financing share gives one maximum price.
The savings ceiling
You need the deposit plus the purchase costs in cash. Dividing your savings by that combined share gives the other maximum price.
Why knowing which one binds matters
If savings are the constraint, waiting and saving raises your ceiling directly. If the payment is the constraint, saving more changes nothing: you need a longer term, a lower rate, or more income. They are different problems with different answers, which is why we name the binding one.
An example
With 2,500 net a month, no other debt, 60,000 saved, 3% over 30 years: the payment ceiling allows roughly 230,000, and the savings ceiling allows about 200,000. Savings are what limit you, so the maximum is 200,000.
Frequently asked questions
Why 35% of income?
It is the usual lending rule of thumb for total debt payments, and it exists to leave you room to live. You can lower it in the field; raising it much above 35% is how people end up trapped.
Why do I need more than the deposit?
Because purchase costs — tax, notary, registry, fees — are around 10% of the price and cannot be borrowed. On a 200,000 flat that is 20,000 on top of the deposit.
Will the bank lend me this much?
Maybe. This applies the standard rules, but a lender also values the property, checks your contract type and job stability, and applies its own policy. Treat it as an upper bound.
