Mortgage calculator and home-buying costs in Luxembourg: what to work out
( In short )
A useful mortgage calculator does not stop at monthly payments: it needs to factor in registration duties (7% on existing property, reduced by the Bëllegen Akt for a primary residence), notary fees, and outstanding-balance insurance. EIRES Real Estate provides a calculator built into its financing guide, for guidance only, alongside a personalised financing plan.
( Key takeaways )
- 01The purchase price is only part of the budget: registration duties, notary fees and outstanding-balance insurance add to the loan's monthly payments.
- 02On existing property, expect 7% in duties (6% registration + 1% transcription) before the Bëllegen Akt applies, which reduces these duties by up to €45,000 per buyer for a primary residence.
- 03Monthly payments depend on three main variables: the amount borrowed, the rate, and the term — a calculator should let each be varied independently to compare scenarios.
- 04Off-plan (VEFA), registration duties apply only to the land share; construction is invoiced with VAT, at 3% for a primary residence under conditions.
- 05A calculator gives an indicative order of magnitude — only a financing file processed by a bank or broker gives a definitive figure.
Beyond monthly payments
A mortgage calculator limited to monthly payments only tells part of the story. Three variables determine the payment itself — the amount borrowed, the interest rate, the term — but the real cost of a purchase in Luxembourg also includes substantial ancillary costs, often underestimated by first-time buyers.
Registration duties, the most significant item
On an existing property, expect 7% of the price in duties (6% registration + 1% transcription) before any reduction. The Bëllegen Akt tax credit then reduces this burden by up to €45,000 per buyer (€90,000 for a couple), but only when purchasing a primary residence — a rental investment or a secondary residence does not benefit from this reduction.
The special case of off-plan purchases (VEFA)
For an off-plan purchase, the calculation changes nature: registration duties apply only to the land share, while the construction itself is invoiced with VAT. For a primary residence, this housing VAT can be reduced to the super-reduced 3% rate, capped at a tax advantage of €50,000 per dwelling. A calculator that does not distinguish existing property from off-plan will give a wrong figure half the time.
Notary, mortgage registration, insurance: the items people forget
Registration duties are followed by notary fees, mortgage registration costs, and the outstanding-balance insurance required by the bank for any mortgage. These items, individually modest, collectively represent a meaningful share of the total budget — to be built in from the first calculation, not discovered at signing.
What a calculator can, and cannot, tell you
A calculator gives an indicative order of magnitude, useful for framing a budget before starting viewings. It does not replace a complete financing file, processed by a bank or a mortgage broker, which alone gives a definitive figure and a firm agreement — rates and terms vary between institutions and change over time.

Our financing guide includes a monthly-payment calculator by price, down payment, rate and term, for guidance only. It comes with personalised support with local banks, from initial budget framing through to the deed.
( Frequent questions )
What should a mortgage calculator include to be genuinely useful?
At minimum: the amount borrowed, the interest rate and the term for monthly payments, but also registration duties, notary fees and outstanding-balance insurance to give a complete picture of the total acquisition cost.
How much are registration duties on an existing property purchase?
Expect 7% of the price (6% registration + 1% transcription) before the Bëllegen Akt applies, which reduces this amount by up to €45,000 per buyer (€90,000 for a couple) when purchasing a primary residence.
Is the calculation different for an off-plan (VEFA) purchase?
Yes: off-plan, registration duties apply only to the land share, while construction is invoiced with VAT — at the super-reduced 3% rate for a primary residence, subject to conditions and caps.
Does an online calculator give a definitive figure?
No, a calculator gives an indicative order of magnitude based on the parameters entered. Only a complete financing file, processed by a bank or a mortgage broker, gives a definitive figure and a firm agreement.
