Building a real estate down payment requires rigorous planning. This calculator allows you to: • Determine how long it will take to reach your goal • Optimize your investment choices according to your horizon • Anticipate the exact amount you will accumulate with compound interest • Adjust your strategy if necessary (monthly savings, duration, investment type) A substantial down payment (10-20% of purchase price) allows you to get better loan conditions and reduce the total cost of your acquisition.
Here are the main products available to build your down payment: • Livret A and LDDS (1.50%): Tax-free, liquid, but capped. Ideal for emergency savings and short-term projects. • PEL (2.00%): Guaranteed rate for 10 years, locked for 4 years. Interesting for medium-term projects with a preferential mortgage rate. • Life insurance euro funds (2.3-3%): No limit, favorable taxation after 8 years. Ideal for long term. • Term deposit (1.8-3.4%): Attractive return but money locked. Suitable for fixed maturities. The choice depends on your time horizon and liquidity needs.
Compound interest is a powerful lever for your savings. Unlike simple interest, compound interest generates interest on itself. Over several years, this multiplier effect can represent several months of "free" savings. Example: €500/month for 5 years at 1.5% (Livret A) = €31,150, including €1,150 in interest. That's the equivalent of over 2 months of free savings! The longer your time horizon, the more significant the compound interest effect.

The 2026 real estate market shows a trend of lower down payment requirements: • The average first-time buyer down payment is around €58,000 (down 11% compared to 2024). • The overall average down payment is around €81,000 in H1 2025. • Banks are more flexible, sometimes accepting down payments of only 10% for primary residences. • For rental investments, a 20-30% down payment is still recommended to get the best conditions. • Remember to keep 3 to 6 months of expenses in reserve: banks require this safety cushion in addition to the down payment.
To calculate your savings effort, first determine your down payment goal (typically 10-20% of the property price), then estimate how much you can save monthly. Our calculator accounts for compound interest on your investment to show you the time needed and the final amount you'll reach.
The choice depends on your time horizon. For less than 2 years, favor Livret A (immediate liquidity). Between 2 and 5 years, PEL can be interesting. For more than 5 years, life insurance offers better returns and favorable taxation after 8 years.
Compound interest is interest calculated on the initial capital AND on already accumulated interest. Over several years, this "snowball" effect can significantly increase your savings. For example, with €500/month for 4 years at 1.5%, you earn approximately €720 in additional interest.
It depends on your monthly savings capacity and chosen investment. With €500/month in a Livret A (1.5%), it will take about 39 months (3 years and 3 months). With €1,000/month, only 20 months. Our calculator gives you a precise estimate based on your situation.
Banks generally recommend a minimum 10% down payment to cover notary fees. For a rental investment, 20-30% down payment improves your loan conditions. First-time buyers can sometimes borrow with only 10% down thanks to PTZ.
Livret A is capped at €22,950. If your goal exceeds this amount, diversify across several products: combine Livret A (€22,950) + LDDS (€12,000) + life insurance (unlimited). This diversification also optimizes your overall return.
Several levers: 1) Automate a monthly transfer upon salary receipt, 2) Progressively increase your savings (+5% per year), 3) Invest bonuses and 13th month, 4) Take advantage of employee savings plans, 5) Diversify investments according to your horizon.
Livret A offers immediate availability, no taxation, but a limit of €22,950 and a rate of 1.5%. Life insurance has no limit, offers better returns (2.3-3% in euro funds), and very favorable taxation after 8 years, but with less liquidity.
Breaking a PEL before 4 years causes loss of the preferential loan right and reduced interest. After 4 years, the accumulated amount can serve as a down payment. In 2026, the PEL rate is 2.00% with taxation at 30% (flat tax). Evaluate whether the preferential loan rate is more advantageous than current market rates before breaking it.
Yes, purchasing a primary residence is a legal early release case for PEE (after 5-year lock-in) and PERCO/PER Collectif. The employer match (up to 300% in some companies) makes this a very efficient savings vehicle. Request the release from your HR or fund manager at least 6 months before your purchase.
For a real estate down payment, life insurance in euro funds is safer: capital guaranteed with returns of 2.3-3% in 2026 and favorable taxation after 8 years. PEA offers potentially higher returns via stock markets, but with capital risk unsuitable for a real estate project with a fixed deadline. Reserve PEA for long-term wealth building, not for a down payment.
Since January 2022, the HCSF limits the debt-to-income ratio to 35% including insurance. If your monthly income doesn't allow sufficient borrowing, you must compensate with a larger down payment. Example: for a €300,000 property with €3,500 net income, the maximum loan at 35% is about €245,000, requiring a €55,000 down payment (18%). Use our debt ratio calculator to check your borrowing capacity.
