Refinancing means moving your mortgage to a bank with a lower margin or interest rate in order to cut the monthly payment. It pays off when the monthly saving covers the cost of moving within a reasonable time — usually 18–36 months. Run it on your own numbers below.
A rough estimate. We prepare the full analysis — transfer costs and bank offers — from your actual loan agreement.

| Property valuation | 600 zł |
| Mortgage entry in the land register | 200 zł |
| Transaction tax on the mortgage | 19 zł |
| Removing the old mortgage | 100 zł |
| Early repayment fee | 0–3% |
| Bridge insurance (until registration) | +1,0 p.p. |
The early repayment fee is capped by the Mortgage Credit Act and depends on the type of interest rate and the time since the agreement was signed.
Balance of 400,000 zł, rate falling from 7.4% to 5.6% over 25 years: the payment drops by about 440 zł/month. With transfer costs of roughly 1,600–2,000 zł the break-even point lands after 4–5 months, and the total saving over the life of the loan exceeds 100,000 zł. Your case will differ — run it on your own numbers above.
It is worth it when the saving on the payment covers the cost of moving within a reasonable time (usually 18–36 months) and genuinely lowers the total cost of the loan.
The costs include the valuation, the mortgage entry, transaction tax, removing the old mortgage, and possibly an early repayment fee and bridge insurance. See the table above.
When the break-even point (costs ÷ monthly saving) falls within a dozen or a few dozen months and the monthly saving is noticeable.
