Mortgage Early Repayment Calculator
Calculate how much you can save by making early repayments on your mortgage. Supports fixed and variable interest rates, extra payments, and amortization schedules.
Why Use This Calculator?
How Early Repayment Works
When you make an extra payment toward your mortgage, the entire additional amount goes toward reducing your principal balance. Because interest is recalculated on the smaller remaining balance each month, you end up paying less interest over the life of the loan — and you pay off the loan faster.
**Example 1:** On a €250,000 mortgage at 5.5% over 30 years, adding €500/month extra from year 2 saves approximately €65,000 in interest and cuts the term by over 6 years.
**Example 2:** On a €200,000 mortgage at 4% over 25 years, adding €300/month saves roughly €28,000 and cuts 4.5 years off the term.
**Example 3:** On a €300,000 mortgage at 6% over 30 years, adding €800/month saves over €100,000 and reduces the term by nearly 10 years.
How to Use the Calculator
1. Enter your loan amount, term, and interest rate (fixed period and rate, plus variable rate)
2. Choose a repayment mode: extra amount on top of your installment, or a fixed total payment
3. Set how much you want to overpay and from which month
4. Review the amortization schedule, charts, and savings summary
The calculator updates instantly and runs entirely in your browser — no data is sent anywhere.
Fees to Watch For
Variable-rate loans: many jurisdictions (including Romania under OUG 50/2010) charge no early repayment fee
Fixed-rate loans: fees are usually limited to about 1% of the amount repaid during the fixed period
Annual overpayment limits: many lenders allow 10-20% of the outstanding balance per year fee-free
Check your contract before overpaying; if your lender charges a high fee, compare whether waiting until the fixed period ends is cheaper.

Frequently Asked Questions
Is early mortgage repayment worth it?▼
Absolutely. Every extra payment reduces your principal balance directly. Since interest is calculated on the remaining balance, a lower principal means less interest accrues over the life of the loan. This can save you tens of thousands in interest and shave years off your mortgage term.
Are there any fees for making early repayments?▼
It depends on your loan agreement. Many lenders allow a certain amount of extra payments per year without penalty (typically up to 10-20% of the outstanding balance annually). Beyond that, a small fee may apply. Always check your mortgage contract or ask your lender about their specific early repayment policy.
What is the difference between "extra amount" and "fixed total" repayment modes?▼
Extra amount means you add a specific sum on top of your regular monthly payment — the extra goes entirely toward your principal. Fixed total means you decide a total monthly payment amount (your regular installment plus extra). For example, if your monthly payment is €1,200 and you set a fixed total of €1,700, the extra €500 goes toward early repayment. The calculator helps you compare both approaches.
How often should I make extra payments for maximum benefit?▼
The earlier and more frequently you make extra payments, the more you save. Monthly extra payments are more effective than quarterly or annual ones because interest accrues on the balance daily in most cases. Even small monthly additions (€100-200) can make a significant difference over a 25-30 year mortgage term.
Should I pay off my mortgage early or invest the money instead?▼
This depends on your mortgage interest rate versus expected investment returns. As a rule of thumb: if your mortgage rate is higher than what you can reliably earn from low-risk investments, early repayment is the better financial move. If your rate is low (under 3-4%), investing may yield better long-term returns. The peace of mind of being debt-free is also worth considering.
