How is the instalment worked out?
Moradot gives you hints like this on everything else you pay for your home, from building fees to rent.
This is an estimate. The figures that count are the ones in the lender's offer.
When the keys are yours
Moradot keeps everything about your home in one place. A few days before each building fee is due you get a reminder, and the proof of every payment stays right next to it.

How the instalment is worked out
Every month, the lender charges interest on what you still owe, at the yearly rate divided by 12. The rest of the instalment repays the loan itself.
Take €200,000 at 4% over 30 years: the instalment is €954.83. In the first month, €666.67 of it is interest and only €288.16 repays the loan. Here’s how to calculate a mortgage payment, step by step.
Equal or decreasing instalments
Equal instalments stay the same as long as the rate doesn’t change. With decreasing ones you repay the same slice of the loan each month plus interest on what’s left, so each is a little lower than the last.
They cost less interest: €120,400.00 instead of €140,042.20 on €240,000 at 4% over 25 years. But the first instalment is €1,600.00, not €1,266.81.
What moves the rate
A rate is either fixed for a number of years or variable. A variable rate is a market reference rate plus the lender’s margin from your contract, so your instalment changes with the market at each review.
Compare offers by the APR, which adds fees and required insurance to the rate. On €240,000 over 25 years, 5% instead of 4% costs €136.21 more a month.
What else to budget for
Buying has costs of its own, such as taxes on the purchase and the notary’s or solicitor’s fees, so keep some savings aside beyond the down payment.
Lenders usually ask for home insurance, often life insurance too. A shared building has monthly fees, and most places a yearly property tax.
Buying in Portugal or Poland
Portugal’s central bank advises loans of at most 90% of a main home’s value and, since 1 August 2026, loan payments within 45% of net income. Under-35s can skip IMT and stamp duty on a first home, within limits.
In Poland, KNF’s Recommendation S advises loans of at most 80% of the value, or 90% with extra cover. A second-hand home pays 2% tax, unless it’s a first home.
Questions people ask
How much can I borrow?
It depends on your income, your other loans and your down payment, and each lender checks it in its own way. Most look at how much of your net income all your loan instalments would take. Try a few amounts here to see what each one would mean for your monthly budget.
How much of a down payment do I need?
It depends on the country and the lender. The more you put down, the less you borrow, and the lower both the instalment and the total interest. The calculator shows your down payment as a share of the price, so you can compare what different amounts would mean.
Is a longer term better?
A longer term lowers the instalment but adds interest. On €240,000 at 4%, taking 30 years instead of 25 brings the instalment down from €1,266.81 to €1,145.80, and adds €32,443.43 of interest.
Is this what the lender will charge me?
It’s an estimate from the rate you enter. Lenders add fees and insurance, and some work out interest by the day. The offer your lender gives you is the one that counts.
