How the Early Mortgage Repayment Calculator Works
The early mortgage repayment calculator is a free tool designed to help you evaluate the financial savings from early repayment, whether partial or total, of your mortgage. By entering a few essential data points such as the current remaining balance, the annual interest rate, the number of remaining installments, and the amount you intend to repay, you can immediately get an accurate estimate of the interest saved.
Why Use This Calculation Tool?
Early mortgage repayment is one of the most effective strategies for reducing the overall cost of your loan. With this calculator, you can:
- Compare different scenarios: evaluate the impact of partial repayments of varying amounts before making a final decision
- Plan ahead: discover how much you could save over the coming years by optimizing the use of your available funds
- Avoid surprises: understand exactly how the number of remaining installments and the interest amount change after an extra payment
- Make informed decisions: compare the interest savings with potential alternative investment returns
Typical Use Cases for the Calculator
This tool is particularly useful in several practical situations:
1. Unexpected Liquidity or Work Bonuses
Have you received a company bonus, an inheritance, or proceeds from selling an asset? Before deciding how to invest these sums, check how much you could save by directing them toward partial mortgage repayment. Often, the interest savings exceed the returns from low-risk investments.
2. Debt Restructuring
If you are considering a mortgage transfer or renegotiation of terms, this calculator allows you to compare the remaining cost of your current mortgage with new offers, also considering the option of a partial repayment before the transfer. You can also use our mortgage payment calculator to simulate the new conditions.
3. Retirement Planning
For those approaching retirement, getting free from the burden of a mortgage can mean greater financial peace of mind. Use the calculator to plan gradual repayments that allow you to pay off the debt before retirement, significantly reducing your financial exposure.
4. Investment Opportunity Evaluation
When you need to choose between paying off the mortgage or investing in other opportunities (funds, stocks, real estate), this tool provides concrete data on the guaranteed savings of repayment. To evaluate alternative returns, try our compound interest calculator.
Calculation Methodology and Reliability
The calculator uses standard financial formulas for calculating installments (French amortization method with fixed payments) and compound interest. The results provided represent an accurate estimate based on the data entered, but it is always advisable to compare them with the official amortization schedule provided by your bank, which may include additional costs, early repayment penalties, or specific rounding. To generate a complete amortization schedule, use our amortization schedule calculator.
Important note: before proceeding with early repayment, always check with your lending institution for any early repayment penalties (abolished for mortgages taken out after 2007 for individuals in Italy, but still possible in some business contracts) and request the official payoff statement.
The payoff statement: what it is and how to read it
The payoff statement (in Italy, “conteggio estintivo”) is the document in which the bank or lender sets out in black and white how much is needed, on a specific date, to close the loan. You request it from the lender and it is the only figure that counts: this calculator tells you whether the operation is worthwhile, the payoff statement tells you exactly how much to pay.
It usually contains four items:
- Remaining principal at the date indicated: this is the bulk of the amount.
- Accrued interest from the last installment paid up to the day of repayment.
- Any penalty or compensation, where still due.
- Administrative fees for closing the file, usually a few tens of euros.
Two practical tips. The statement has a validity date: if you pay later, the accrued interest changes and you need an updated statement. And it should be compared with the amount you actually have: if it exceeds your available funds, consider a partial rather than a total repayment — the calculator above works for that too.
Don't know your remaining debt? How to work it out
The first field of the calculator asks for the remaining debt, i.e. the principal you still have to repay, excluding future interest. It is not the sum of your remaining installments: that also includes the interest that, by repaying early, you will not pay.
The quickest way to get it is to look at the amortization schedule attached to the contract, which shows the remaining principal installment by installment, or your online banking, where it usually appears as “remaining debt” or “outstanding principal”.
If you have neither, you can estimate it from the installment. With French amortization — the fixed-payment method, the most common in Italy — the formula is:
Remaining debt = Payment × [1 − (1 + i)−n] ÷ i
where i is the monthly rate (the annual rate divided by 12, in decimal form: 3.5% a year → 0.035 ÷ 12 = 0.0029167) and n is the number of installments remaining.
Example: payment of €571.91, rate 3.5% a year, 180 remaining installments. The calculation gives about €80,000 of remaining debt. It is an estimate: if your mortgage has a variable rate the value changes at every rate revision, so for the actual operation the bank's statement always prevails.
Personal loans, financing and salary-backed loans: the rules differ
This tool calculates the interest savings for any fixed-payment loan, but the legal framework differs depending on the product.
Mortgages
For mortgages taken out by individuals from February 2, 2007, for the purchase or renovation of a residential property or for their own business or professional activity, the Bersani Decree (art. 7 of D.L. 7/2007) made the penalty clause null and void. For earlier contracts, the caps of the ABI–Consumer Associations agreement of May 2, 2007 still apply, which eliminates the penalty in the last two years of amortization.
Personal loans and consumer credit
Article 125-sexies of the Italian Consolidated Banking Act (TUB) applies: the compensation cannot exceed 1% of the amount repaid if the remaining term of the contract exceeds one year, 0.5% if it is one year or less, and in no case can it exceed the interest you would have paid over the remaining period. It is not due, among other cases, when you repay the entire remaining debt and this does not exceed 10,000 euros.
Salary-backed loans (cessione del quinto)
This is the case where you recover the most, and it is often overlooked. With ruling no. 263 of December 22, 2022 the Constitutional Court established that, in case of early repayment, all unaccrued costs must be refunded in proportion to the unused period: not only those linked to duration, such as interest and insurance premiums, but also the up-front costs paid at the start — arrangement fees, brokerage fees, distribution network charges. Taxes are excluded. The distinction between recurring and up-front costs, which lenders used to limit refunds, no longer applies. For contracts signed before July 25, 2021, however, DL 69/2023 then established that taxes and the costs incurred for concluding the contract are not subject to reduction (art. 11-octies, paragraph 2, of DL 73/2021, as amended), without prejudice to the Civil Code rules on undue payment and European Union law.
In practice: if you repaid a salary-backed loan early and were refunded only the interest, you may be entitled to a further sum. The savings shown above concern interest; up-front costs must be claimed separately from the lender.
