Overpaying or fully repaying a mortgage early is one of the most effective ways to reduce the cost of the commitment. Every złoty paid above the instalment reduces the principal on which interest is charged.

Before you decide to put your savings towards repaying the loan, however, it is worth understanding the rules, the potential fees and how the choice between shortening the term and lowering the payment affects the financial outcome.

Key takeaways

A mortgage can be repaid early in full or in part, which reduces the total interest paid.
With an overpayment you usually choose between shortening the loan term and lowering the size of the instalment.
The bank may charge compensation for early repayment, especially on a fixed rate — the rules are governed by the act and the contract.
Before overpaying, it is worth checking the procedure at the bank and comparing the benefit with an alternative use of the money.

What early repayment involves

Early repayment is a payment exceeding the standard instalment. It can be partial, when you overpay part of the principal, or total, when you close the loan in full before its due date. In both cases the outstanding principal falls, and this directly translates into a lower amount of interest paid in the future.

The right to early repayment belongs to the borrower, and its rules are governed by the Mortgage Loan Act and the terms of the contract. It is worth reviewing those provisions before deciding on an overpayment.

Shortening the term or lowering the payment

With a partial overpayment the bank usually gives you a choice between two effects. Shortening the loan term while keeping the current instalment saves the most on interest, because the loan finishes sooner. Lowering the instalment while keeping the term, in turn, gives more day-to-day comfort in the household budget.

The choice depends on your priorities. If the goal is maximum saving, shortening the term is usually more advantageous. If, however, you care about security and a lower monthly burden, lowering the payment tends to make more sense. It is worth asking the bank which option is set by default.

Compensation for early repayment

The bank may charge compensation, that is a fee for early repayment, but the rules are limited by law. For variable-rate loans the possibility of charging compensation is limited to a period of time from when the loan was granted, and its amount is capped. For a periodically fixed rate the rules may differ and the fee may apply for longer.

That is why, before overpaying, it is worth checking the contract and terms to see whether compensation would apply in your case at all and in what amount. Even if the fee does appear, the benefit of the interest saved often outweighs its cost, but this has to be calculated individually.

When overpayment pays off

An overpayment is the more advantageous the higher the loan's interest rate and the earlier the repayment stage, because that is when the share of interest in the instalment is greatest. It is always worth comparing it, however, with the alternatives: keeping a financial cushion for sudden expenses or otherwise safely investing the money.

There is no point in overpaying a loan at the cost of losing your entire financial reserve. The sensible approach is to keep a safety buffer and put towards overpayment only the part of your savings you will not need in the near future.

Summary: a powerful tool worth calculating

Early repayment of a mortgage can significantly reduce the total cost of the commitment, especially in the early years of repayment. The key decisions are the choice between shortening the term and lowering the payment, and checking any compensation. Always compare the benefit against keeping a financial cushion. Before any larger overpayment, review the contract provisions and the procedure in force at your bank.

Frequently asked questions

Will I pay an extra fee for early repayment?

Compensation may apply, but charging it is limited by law. With a variable rate the possibility of charging it is time-limited and the amount is capped. Always check the provisions of your contract and terms.

Is it better to shorten the loan term or lower the payment?

Shortening the term usually gives a greater saving on interest, while lowering the payment improves current budget comfort. The choice depends on your priorities. It is worth asking the bank which option it sets by default after an overpayment.

When does overpayment bring the greatest benefit?

You gain the most by overpaying in the early years of the loan and at a higher interest rate, because that is when the share of interest in the instalment is greatest. Always keep a financial cushion for sudden expenses, though.

How do I request early repayment?

The procedure depends on the bank — you usually submit an overpayment instruction and indicate whether it should shorten the term or lower the payment. It is worth doing this per the bank's instructions so the payment is correctly booked as an overpayment of principal.
