Use this mortgage calculator to estimate how large your loan amount, monthly payment, remaining balance and interest cost may be when buying property. It takes into account purchase price, closing costs, equity, interest rate, initial repayment rate, analysis period and optional annual extra repayments.
Mortgage Calculator: Plan mortgage affordability and understand remaining debt
Use the result as decision support, not as individual advice. For finance topics, scenarios, total cost, risk, term and personal affordability matter.
How to use the result better
- Calculate conservative, realistic and optimistic cases.
- Look beyond monthly values to total cost or final value.
- Keep safety buffers before making a decision.
Common mistake
One attractive figure can mislead when fees, taxes, rate changes, volatility or long terms are ignored.

Is this financial advice?
No. It is an orientation tool and does not replace individual financial, tax or investment advice.
Why are scenarios so important?
Small changes in interest, return, term or costs can change the result significantly.

How the result is calculated
Total capital needed = purchase price + closing costs
Loan amount = total capital needed − equity
Annual payment = loan amount × (interest rate + initial repayment rate)
Monthly payment = annual payment ÷ 12
Remaining balance = loan balance after interest, principal repayment and optional extra repayments over the selected period
Equity share = equity ÷ total capital needed
Debt share = loan amount ÷ total capital needed
Worked example
Example: A property costs €450,000 and closing costs are €45,000. With €120,000 in equity, the financing need is €375,000. At 3.6% interest and a 2.0% initial repayment rate, the annual payment is €21,000 or about €1,750 per month. After 15 years, a remaining balance usually still exists depending on extra repayments.
What does the mortgage calculator calculate?
The calculator estimates total capital needed, the resulting loan amount, the initial monthly payment, interest paid and the remaining balance after the selected period. It also shows how much of the loan has already been repaid and how strongly your equity reduces the financing burden.
Why do closing costs matter so much?
Many buyers underestimate closing costs. These usually include transfer tax, notary, land registry and often broker fees. They significantly increase the actual capital needed and directly affect how large the final loan must be.
Why is the equity share so important?
A higher equity share reduces leverage and often improves financing terms. It can also lower monthly payment, remaining balance and long-term risk. In property financing, equity is one of the strongest levers for stability.
How does the repayment rate affect the mortgage?
A higher initial repayment rate increases the ongoing monthly payment, but it also reduces the remaining balance more quickly. That often lowers future refinancing pressure. Saving too much on repayment at the start may only help in the short term.
When do extra repayments help?
Extra repayments can reduce the remaining balance significantly and make the overall financing structure more resilient. Even moderate annual extra payments can create a meaningful effect over time. This calculator makes that effect visible.
Why is the remaining balance after the fixed-rate period so important?
Many mortgages are not fully repaid by the end of the first fixed-rate period. The remaining balance must then be refinanced later. The lower that balance is, the easier refinancing usually becomes.
How should you interpret the results?
Use the results as first guidance, not as a binding financing offer. For real decisions, you should also include household budgeting, reserves, renovation costs, subsidies, refinancing risk and your broader life plans.
Why is the mortgage calculator strategically important?
This calculator is especially useful when you want to compare home financing scenarios with different equity, rates, repayment levels and terms. It helps you see how monthly payment, remaining balance and total cost change under realistic assumptions.
Frequently asked questions
What is a good equity share?
Lenders often view a stronger equity share positively. In many cases, it is considered sensible to cover at least the closing costs from your own funds, often more if possible.
How high should the repayment rate be?
A higher repayment rate reduces debt faster but also raises the monthly payment. In practice, many borrowers choose around 2% or more if their budget allows it.
Why is there often a remaining balance after the fixed-rate period?
With classic mortgages, the loan is usually not fully repaid during the first fixed-rate period. That is why refinancing is often needed later.
Should I finance the closing costs too?
That may be possible, but it usually increases leverage and risk. Many buyers therefore try to cover at least the closing costs with equity.
What is the benefit of extra repayments?
Extra repayments reduce the remaining balance and can make the financing much more stable. This can be especially valuable over long periods.
Are the results binding?
No. The calculator is for first guidance only. Actual lender terms and underwriting determine the real financing offer.
Can I compare different financing setups with it?
Yes. That is one of its main strengths. You can change equity, repayment rate, interest rate, timeframe and extra repayments and compare the impact directly.
Does this replace mortgage advice?
No. The calculator helps with planning and first assessment, but major decisions should be based on real offers and, where needed, independent advice.
