A €200,000 mortgage over 30 years at a fixed 3% costs €843.21 a month and €103,555 in total interest. Over 25 years the payment rises to €948.42 and interest falls to €84,527; over 20 years, €1,109.20 and €66,207. At September 2026’s 12-month Euribor (3.247%) with no margin, the 30-year payment would be €870.08.
To work out the payment with your own numbers, use the mortgage calculator; to see whether your salary can carry it, the mortgage affordability calculator. Below: a payment table for €100,000 to €300,000, total interest by term, what 3.247% really means, and the formula so you can check it yourself.
How much do you pay on a €200,000 mortgage?
With French amortisation (a fixed monthly payment, the norm in Spain), the result depends only on the loan, the rate and the term. For €200,000 at a fixed 3%:
| Term | Monthly payment | Total interest | Total repaid |
|---|---|---|---|
| 20 years (240 payments) | €1,109.20 | €66,207 | €266,207 |
| 25 years (300 payments) | €948.42 | €84,527 | €284,527 |
| 30 years (360 payments) | €843.21 | €103,555 | €303,555 |
Early on, interest makes up most of the payment. In the first 30-year payment, €500 is interest (200,000 × 3% ÷ 12) and only €343.21 repays principal. Over the first 12 months you pay €10,118.50: €5,942.90 of interest and just €4,175.60 of principal. That is why the debt falls so slowly in the first years of a long mortgage.
What is the payment on a €100,000 to €300,000 mortgage?
Monthly payments at two rates: a fixed 3% (example assumption) and 3.247% (12-month Euribor for September 2026, no margin). The tables round to whole euros, like the calculator; the cents in the text come from the same formula.
Monthly payment at a fixed 3%:
| Loan | 20 years | 25 years | 30 years |
|---|---|---|---|
| €100,000 | €555 | €474 | €422 |
| €150,000 | €832 | €711 | €632 |
| €180,000 | €998 | €854 | €759 |
| €200,000 | €1,109 | €948 | €843 |
| €250,000 | €1,386 | €1,186 | €1,054 |
| €300,000 | €1,664 | €1,423 | €1,265 |
Monthly payment at 3.247% (Euribor with no margin):
| Loan | 20 years | 25 years | 30 years |
|---|---|---|---|
| €100,000 | €567 | €487 | €435 |
| €150,000 | €851 | €731 | €653 |
| €180,000 | €1,021 | €877 | €783 |
| €200,000 | €1,134 | €974 | €870 |
| €250,000 | €1,418 | €1,218 | €1,088 |
| €300,000 | €1,701 | €1,461 | €1,305 |
The payment is proportional to the loan: €100,000 over 30 years at 3% is €421.60; twice the loan, twice the payment (€843.21).
How much interest do you pay in total by term?
Total interest at a fixed 3%, with no early repayments:
| Loan | 20 years | 25 years | 30 years |
|---|---|---|---|
| €100,000 | €33,103 | €42,263 | €51,777 |
| €150,000 | €49,655 | €63,395 | €77,666 |
| €180,000 | €59,586 | €76,074 | €93,199 |
| €200,000 | €66,207 | €84,527 | €103,555 |
| €250,000 | €82,759 | €105,658 | €129,444 |
| €300,000 | €99,310 | €126,790 | €155,332 |
At 3.247%, interest on €200,000 rises to €72,181 (20 years), €92,295 (25 years) and €113,230 (30 years). Over 30 years, a quarter of a point more costs almost €10,000 extra in total.
Is a 25-year or a 30-year mortgage better?
It depends on what matters more to you: the monthly payment or the total cost. With €200,000 at 3%:
- 30 vs 25 years: €105.21 less a month, but €19,028 more interest.
- 30 vs 20 years: €265.99 less a month, but €37,348 more interest.
A long term leaves room in your budget and improves the affordability ratio the bank looks at. A short term saves interest. There is a middle way: sign for 30 years and make early repayments when you can, if your contract’s fees allow it. If you are buying to let, a lower payment also improves DSCR (net rent ÷ annual debt service).
What is 3.247% and how does the rate change the payment?
3.247% is the 12-month Euribor for September 2026, the monthly average published by the Banco de España (BOE-A-2026-20519, Spanish Official Gazette of 2/10/2026 — in Spanish). It is not a mortgage rate: it is the reference index. A variable-rate mortgage pays Euribor + a margin (diferencial) and is reset every 6 or 12 months. A fixed-rate mortgage has whatever rate (TIN) the bank offers, with no direct link to that month’s Euribor. We use 3.247% on its own as a marker of today’s level; with any margin, the payment will be higher.
Payment on €200,000 over 30 years by rate:
| Rate | What it represents | Payment | Total interest |
|---|---|---|---|
| 2.5% | Low fixed rate (assumption) | €790.24 | €84,487 |
| 3% | Example fixed rate (assumption) | €843.21 | €103,555 |
| 3.247% | 12-month Euribor Sept 2026, no margin | €870.08 | €113,230 |
| 3.747% | Euribor + 0.5 points (assumed margin) | €925.89 | €133,321 |
| 4% | High fixed rate (assumption) | €954.83 | €143,739 |
| 4.247% | Euribor + 1 point (assumed margin) | €983.53 | €154,070 |
The margins in the table are examples, not offers. On a variable mortgage, each reset recalculates the payment with the Euribor of that moment on the outstanding balance, so these figures only hold while the index stays put. Always compare offers by APR (TAE): it includes fees and bundled products, and the TIN does not.
How to calculate the mortgage payment
It is the French amortisation formula, the same one Ladrillómetro’s calculator uses:
Payment = L × r ÷ [1 − (1 + r)−n], where L is the loan, r the annual rate ÷ 12 and n the number of months.
- Loan: L = €200,000.
- Monthly rate: r = 3% ÷ 12 = 0.0025.
- Number of payments: n = 30 × 12 = 360.
- Payment: 200,000 × 0.0025 ÷ (1 − 1.0025−360) = €843.21.
- Total interest: 843.21 × 360 − 200,000 ≈ €103,555.
Open this example in the calculator
The calculator does not read values from the URL yet, but it opens with this same example: price €250,000 and €50,000 down payment (a €200,000 loan) over 30 years. Just change the interest rate from 3.5 to 3. You will see a €843 payment (rounded to euros), €103,555 of interest and €303,555 repaid. Tap 25 or 20 years to see €948 and €1,109.
What salary do you need for a €200,000 mortgage?
If the bank caps the payment at 35% of net income (with no other debts), a €843.21 payment needs about €2,409 net a month over 30 years. Over 25 years it would be €2,710, and over 20 years, €3,169. At 3.247% those rise to €2,486, €2,784 and €3,240. It is a rule of thumb: each lender also looks at income stability and savings. The reverse calculation (how much they will lend on your salary) is in How much mortgage can I get with my salary?.
Does the payment include insurance, taxes and fees?
No. The payment is just principal plus interest. On top of it you pay:
- Property running costs: IBI (council tax), community fees and home insurance. The calculator adds them in “Housing cost incl. expenses”.
- Bundled products: life insurance, salary deposit or cards, if the offer requires them for that rate.
- Down payment and buying costs: banks usually lend up to ~80% of the valuation for a main home. The rest, plus ITP or VAT, notary and land registry, comes from your savings. Work them out with the home buying costs calculator.
