Notary fees, or acquisition costs, only partly pay the notary. They mainly consist of transfer duties (taxes paid to the State and local authorities), plus the notary's emoluments, disbursements and the property security contribution (CSI). The amount depends on the price, the property type and its location.
The calculation used here is deliberately simplified: two rates applied to the taxable base.
Taxable base = purchase price − deductible furniture − buyer agency fees
Transfer duties = taxable base × transfer duty rate
Other costs = taxable base × other costs rate
Notary fees = transfer duties + other costs
Total acquisition budget = purchase price + buyer agency fees + notary fees
Agency fees payable by the buyer are excluded from the taxable base: they are not part of the base for notary fees, but they are added to the total budget. Deductible furniture (fitted kitchen, furnishings) is also subtracted from the base.
For an existing home bought for €250,000, with no furniture or agency fees, a transfer duty rate of 4.50% and an other-costs rate of 1.30%:
Transfer duties: 250,000 × 4.50% = €11,250.
Other costs: 250,000 × 1.30% = €3,250.
Estimated notary fees: 11,250 + 3,250 = €14,500.
Total acquisition budget: 250,000 + 14,500 = €264,500.
For existing property, the transfer duty rate depends on the département: since the 2025 finance law, it can be raised up to 5% outside special cases. For new builds, the tax regime is different and duties are much lower (around 0.7%): select "New build" to apply a reduced default rate, which you can adjust.
Some situations (first-time buyers, main residence, local exemptions) may reduce the applicable rate. This calculator does not model them automatically: adjust the transfer duty rate accordingly to get an estimate closer to your own case.
