€300,000 Mortgage at 3.5%: Deposit Versus Loan Principal
This euro-denominated mathematical example starts with a €300,000 property price and no deposit, so the initial loan principal is €300,000. It applies a selected 3.5% nominal annual interest rate over 25 years. Local taxes, insurance, recurring property charges, transaction costs, maintenance, subsidies, and lender fees are excluded from the headline payment.
How does a down payment change a €300,000 mortgage?
With no deposit, the selected property price and loan principal are both €300,000, producing an estimated principal-and-interest payment of €1,501.87. A deposit reduces the amount financed; it is separate upfront cash rather than an extra loan payment.

Detailed Breakdown
Compare deposit cash with the resulting loan principal
The table holds the €300,000 property price, selected 3.5% nominal annual rate, and 25-year term constant. It changes only the selected deposit percentage, then recalculates the principal, monthly payment, and total interest with the shared finance functions.
| Deposit | Upfront deposit | Loan principal | Monthly payment | Total interest |
|---|---|---|---|---|
| 0% | €0.00 | €300,000.00 | €1,501.87 | €150,561.21 |
| 10% | €30,000.00 | €270,000.00 | €1,351.68 | €135,505.09 |
| 20% | €60,000.00 | €240,000.00 | €1,201.50 | €120,448.97 |
A 10% selected deposit produces a €270,000.00 loan principal and a €1,351.68 monthly payment. A 20% selected deposit produces a €240,000.00 principal and a €1,201.50 payment. The lower payments must be weighed against the larger upfront cash contribution.
What the deposit comparison does not decide
The table does not model the return or liquidity of cash kept outside the purchase, local deposit requirements, transaction charges, taxes, insurance, maintenance, valuation costs, subsidies, or lender eligibility. It is a mathematical comparison rather than guidance for a particular country or loan product.
Replace every assumption with a written local offer and documented costs. For a term-focused comparison, see the €200,000 mortgage scenario; for another principal comparison, see the €350,000 scenario.
Key Considerations
Enter the down payment and any quoted mortgage-insurance cost for the loan you are considering.
Use the interest rate and fees from a written quote; pricing criteria vary by lender and loan program.
Consider a 15-year term if you want to save massively on total interest.
Add closing costs from a written estimate for your loan and jurisdiction.
Frequently Asked Questions

No. Any income ratio shown is an illustrative stress-test assumption. Approval and affordability rules vary by country, lender, loan product, and borrower.
What market does this euro scenario cover?
It is a euro-denominated mathematical example rather than country-specific mortgage guidance. Use a local quote and local cost inputs for a real decision.
