About

Optimisation Épargne is an independent tool, born from a simple idea: making long-term saving mechanics readable (contributions, fees and inflation, retirement withdrawals, market uncertainty) — no jargon, no account required.

What the site does (and doesn’t do)

• It simulates: projected capital, before-tax withdrawals, contribution strategies and Monte Carlo scenarios. The simulator does not model taxes.
• It is not an advisor: no personalized recommendations, no products sold directly. Estimates are indicative.
• It collects nothing: everything is computed in your browser.

How the site is funded

The site is free. Some outbound partner links are paid and clearly labelled (“partner link”). These partnerships do not change the calculations or educational content. No personal data is sold. Read the simulator’s assumptions and limits.
