How this calculator works

The calculator amortises your outstanding balance twice over the same remaining term, once at your current rate and once at the new rate, and takes the difference. That gives the monthly saving and the interest you would save over the term. It then nets off the one-off cost of switching: solicitor and valuation fees, plus any break fee, less any cashback the new lender pays. What remains is the net benefit, and the break-even is how long the monthly saving takes to cover a net cost.

A switch worth making

Say you owe €250,000 with 25 years left at 4.5%, and you can move to 3.0%. The repayment falls from about €1,390 to about €1,186, a saving near €204 a month, and roughly €61,200 of interest over the remaining term. With €1,500 in fees and no cashback you break even in about eight months. Add €3,000 of switcher cashback and the costs are covered from the start, so the saving is yours from month one.

Costs, cashback, and break fees

Three things decide whether a switch pays. Switching costs run to roughly €1,200 to €2,500 for legal and valuation work. Cashback, offered by most Irish lenders at around €1,500 to €3,000 or 2% to 3% of the loan, offsets those costs. A break fee applies only if you leave a fixed rate early, so a variable-rate borrower has none; always get the figure in writing from your lender first.

Is switching worth it?

  • Rate gap — a difference of about 0.5% or more usually makes the numbers work.
  • Time left — the more years remaining, the larger the interest saving.
  • Cashback vs costs — cashback that exceeds your costs means an immediate break-even.
  • Break fee — on a fixed rate, weigh the quoted early repayment charge against the saving.

A note on accuracy

This tool holds both rates constant over the horizon, so it compares today's rates rather than predicting rate moves, and it does not include a new mortgage-protection premium. Confirm your break fee with your lender and compare current rates and cashback through the CCPC mortgage comparison and Citizens Information. See our methodology for the formulas.

Frequently asked questions

Is it worth switching my mortgage in Ireland?

As a rule of thumb, switching is worth looking at when the new rate is at least about 0.5% lower than your current one and you have more than five years left on the term. The saving on a lower rate usually dwarfs the one-off costs within months, and cashback often covers those costs outright. This calculator shows the net benefit for your own numbers rather than a rule of thumb.

How much does it cost to switch?

Switching normally costs about €1,200 to €2,500 in solicitor and valuation fees. You may also need a new mortgage protection policy. Many lenders offer switcher cashback of roughly €1,500 to €3,000, or 2% to 3% of the loan, which can cover the costs and sometimes leave money over.

What is a break fee (early repayment charge)?

If you are on a fixed rate and leave it before the fixed period ends, your lender can charge a break fee, also called an early repayment charge. It reflects the cost to the lender of ending the fixed deal early and depends on how market rates have moved, so it can be zero or a few thousand euro. Variable rates have no break fee. Ask your lender for a written break-fee quote before you switch.

Can I switch while I am on a fixed rate?

Yes. You can switch mid-way through a fixed rate, but you weigh any break fee against the saving. Enter the quoted break fee here and the calculator folds it into the net benefit and break-even. Re-fixing with your current lender is a simpler alternative that avoids solicitor fees, though it may not reach the best market rate.

Where can I compare switcher rates?

The Competition and Consumer Protection Commission (CCPC) runs an independent mortgage comparison with a switchers view, which is a good starting point for the rates and cashback offers currently available. Your own eligibility depends on the Central Bank income and deposit limits and each lender’s assessment.
