How this mortgage repayment estimate is calculated
The calculator estimates repayment mortgage costs from the loan amount, interest rate, mortgage term, and any optional overpayments.
- The mortgage amount is estimated from the property price minus the deposit.
- The selected interest rate and term are used to calculate an estimated monthly repayment.
- Total repayable and total interest are estimated over the full term.
- Optional overpayments are modelled separately to show possible interest and term savings.

About This Mortgage Calculator Ireland
This mortgage calculator Ireland helps you estimate monthly mortgage repayments, total interest, total repayable amount, upfront buying costs, and optional overpayment scenarios before you speak to a lender or broker.
Enter the property price, deposit, interest rate, and mortgage term to calculate the estimated monthly repayment for a repayment mortgage. The calculator also shows the mortgage amount, loan-to-value ratio, deposit percentage, estimated stamp duty, and a simple rate stress test.
The Loan-to-Value (LTV) ratio is the mortgage amount expressed as a percentage of the property value. For principal home mortgages, first-time buyers and second/subsequent buyers generally work around a 90 % maximum LTV, while buy-to-let purchases generally use a lower LTV limit.
The results are estimates only. Actual mortgage approval, repayments, rates, fees, and conditions depend on your lender, income, expenses, credit profile, mortgage type, and current Central Bank and lender rules.

Example Monthly Mortgage Repayments
Many users search for repayments on a 200k, 300k, or 400k mortgage. The examples below show how monthly mortgage repayments can change by loan amount when the interest rate and term stay the same.
These examples assume a 30-year repayment mortgage at 4.00% interest. They are for illustration only, because your real repayment will depend on the rate, term, mortgage type, and lender offer available to you.
| Mortgage amount | Example monthly repayment | Total repayable | Total interest |
|---|---|---|---|
| €200,000 | €955 | €343,739 | €143,739 |
| €300,000 | €1,432 | €515,609 | €215,609 |
| €400,000 | €1,910 | €687,478 | €287,478 |
| €500,000 | €2,387 | €859,348 | €359,348 |

How Mortgage Repayments Are Calculated
A mortgage repayment calculator uses the loan amount, interest rate, and term to estimate the regular payment needed to repay both capital and interest over time.
For a standard repayment mortgage, each monthly payment includes interest on the outstanding balance and a capital repayment that reduces the loan. Early in the term, more of the payment goes towards interest. Later in the term, more goes towards reducing the balance.
A longer mortgage term usually lowers the monthly repayment, but it can increase the total interest paid over the full mortgage. A shorter term usually increases the monthly repayment, but can reduce the total interest cost.
Interest rate changes can have a large effect on repayments. That is why the result panel includes a rate comparison and a simple stress-test view, helping you see how the payment could move if rates increased.
Extra Repayments and Overpayments
If your lender allows overpayments, paying a little extra each month or making a lump-sum repayment can reduce the total interest and shorten the mortgage term.
| Example overpayment | Estimated time saved | Estimated interest saved |
|---|---|---|
| €100 extra per month | 3 years 6 months | €28,747 |
| €200 extra per month | 6 years 2 months | €50,412 |
| €10,000 lump sum | 1 year 10 months | €21,972 |
| €100 monthly + €10,000 lump sum | 5 years | €46,716 |
Example based on a €300,000 mortgage over 30 years at 4.00%. Fixed-rate mortgages may have overpayment limits or break fees, so always check your lender terms first.
