Mortgage refinancing compares the remaining loan with a new financing offer including rate, term, insurance, penalties and fees. The goal is not only to lower the payment; it is to know whether the transaction creates real savings after all costs. This page helps identify the break-even point before speaking with a lender or broker.
Net savings = remaining cost of current loan - total cost of new loan including fees
Each scenario calculates an amortizing payment from remaining principal, monthly rate and number of months. Total cost adds payments, insurance and refinancing fees. Net savings equal the remaining cost of the old loan minus the full cost of the new loan and associated fees.
Example refinancing assumption: moving €250,000 remaining from 2.45% over 18 years to 1.15% over 15 years may cut interest by about €37,100. After roughly €5,763 of estimated fees and penalties, the simulation still shows around €37,300 of net gain, despite a total monthly payment about €60 higher.
Refinancing can make sense if interest and insurance savings recover the fees before you sell or before the loan ends. Read payment, remaining term, total cost and break-even together; one attractive number can hide a weak deal.
The new loan refinances what is still owed, not the original purchase price. This base drives the new payment and future interest.
Before accepting an offer, estimate the remaining cost of the current loan: future interest, insurance and remaining term. This is the real comparison point.
Prepayment penalties, application fees, guarantees, brokerage and other charges reduce savings. Ignoring them can turn a profitable refinancing into a neutral one.
Cheaper insurance strengthens the deal; more expensive insurance can erase it. Compare the full monthly cost, not only the bank payment.
Shortening the term often improves total cost but increases monthly effort. Extending the term can ease cash flow while raising the final cost.
If you may sell in two or three years, fees must be recovered before that date. Otherwise the theoretical full-term saving will never be captured.
For a financial decision, do not keep only the payment, return or final amount. Check total cost, fees, duration, possible inflation and available cash flow to understand what the result really implies. This extra context makes the estimate easier to compare with a quote, statement or long-term plan.
Increase the rate, lower the expected return or add fees to see how resilient the result is. If a small change removes the safety margin, treat the number as a fragile assumption rather than a secured target. Keep the cautious case visible before committing money.
An online finance calculation helps prepare comparisons, but it does not replace a bank offer, statement, tax document or contract. Before acting, reconcile the result with official documents and rules that apply to your situation.
Keep the entered values, date, currency, rate, term and fees included or excluded. This record makes the simulation repeatable and explains why two similar outputs can lead to different decisions.
Simplified comparison with assumptions: €250,000 remaining, old loan at 2.45% over 18 years, new loan at 1.15% over 15 years.
| Item | Old loan | New loan |
|---|---|---|
| Payment with insurance | ≈ €1,497 | ≈ €1,558 |
| Estimated interest | ≈ €59,415 | ≈ €22,302 |
| Estimated insurance | ≈ €14,040 | ≈ €8,100 |
| Refinancing fees | — | ≈ €5,763 |
Check whether the rate gap really offsets fees and insurance changes.
Measure total savings if you accept a higher payment.
Verify that monthly relief does not come with a higher total cost.
Compare the break-even date with the likely sale date.
This estimate is general information, not personalized banking, legal or financial advice. Real conditions depend on the loan offer, APR, insurance, guarantees, exact penalties, possible tax effects and how long you plan to keep the property.
There is no universal threshold. The gap must cover fees, insurance and the remaining term.
They depend on the contract and repayment reason. Check the loan offer.
Yes. APR gives a more complete view than the nominal rate alone.
No. It can be profitable with a higher payment if term and interest fall sharply.
