Malta · Mortgage Decision

Finish sooner, or invest instead?

By Ian Grima Mahoney · Updated May 2026

See how much sooner your Maltese mortgage finishes — and how much interest you avoid — with a monthly over-payment or a one-off lump sum, then weigh it against the same money in an ETF, post-tax. Data current as of May 2026.

Over-paying a mortgage is a guaranteed, risk-free return equal to your loan rate — and because Malta does not let you deduct home-loan interest on your own residence, that return is effectively tax-free. Investing the same money in a low-cost world-equity ETF has a higher expected return but real market risk and Malta's 15% tax on the gain at disposal. This tool runs both paths over the same horizon with the same total cash, so the comparison is honest rather than a slogan.

Frequently asked questions

Should I overpay my mortgage or invest the money in Malta?

It comes down to two numbers: your mortgage rate and the post-tax return you'd realistically earn investing instead.

Over-paying is a guaranteed, risk-free return equal to your loan rate — and because Malta doesn't let you deduct home-loan interest on your own residence, it's effectively tax-free. A global ETF has a higher expected return but carries market risk and Malta's 15% tax on the gain at disposal.

As a rule of thumb: a ~3–3.5% mortgage versus a 6–7% world-equity ETF usually favours investing over a long horizon — but a low expected return or a high mortgage rate flips it toward overpaying. There's no universal answer; certainty has value too. Run your own numbers above.

Can I deduct home-loan interest from tax in Malta?

Not for the loan on your own home. Malta allows an interest deduction against rental income for a let property, but interest on the mortgage on your primary residence is not tax-deductible.

That's what makes over-payment a clean comparison: the interest you avoid is a fully tax-free saving, so clearing a 3.5% mortgage early is like earning a guaranteed 3.5% after tax. Any investment alternative has to beat that after Malta's 15% tax on the gain. Confirm your own position with cfr.gov.mt or an adviser.

How is the interest avoided and time saved calculated?

The calculator amortises your mortgage month by month. Each month it charges interest on the outstanding balance at one-twelfth of your annual rate, then applies the standard payment plus your extra (and any one-off lump in the month you choose) to the principal, until the balance hits zero.

The months between that early payoff and your original end date is the time saved; the gap between the original schedule's total interest and the accelerated schedule's is the interest avoided. The original total interest uses the standard annuity payment over the full original term.

Is the overpay-versus-invest comparison fair?

Yes. Both paths spend exactly the same total cash over the same horizon and both end with a zero mortgage balance.

  • Overpay: direct the standard payment + extra at the mortgage; once it clears early, invest the now-freed cashflow in the ETF for the months remaining to the original end date.
  • Invest: keep paying only the standard payment and invest the extra (and any lump) from day one.

Because total outflow and the end balance are identical, the whole difference at the horizon is the post-tax ETF value — and the interest you saved by clearing the loan early shows up as the larger freed cashflow the overpay path gets to invest later.

Are there early-repayment penalties on Maltese mortgages?

It varies by lender and product. Variable-rate Maltese home loans typically allow partial over-payments and lump-sum reductions without a penalty — the common case modelled here. Breaking a fixed-rate deal early can attract a charge.

Before committing to a regular over-payment plan, check your loan agreement or ask your bank in writing whether partial prepayments are free and whether they shorten the term or reduce the monthly payment. This calculator assumes the term shortens while the payment stays the same, which maximises interest saved.

Does a lump sum or a monthly over-payment clear the loan faster?

Per euro, the earlier the money lands the more interest it kills, because it shrinks the balance every future interest charge is calculated on. An early lump sum saves more interest than the same amount drip-fed monthly over many years; a monthly over-payment is more accessible and still compounds over time.

The strongest result combines an early lump with an ongoing monthly extra. Use the lump-sum-in-year input to see how the timing of a windfall changes the payoff date and total interest.
