About Finopact
Finopact makes financial calculations easier to read, helping you understand your options before making a decision.
Last updated: 7 September 2026Our mission
Financial decisions often rely on calculations that are difficult to verify or results shown without explanation. Finopact turns those calculations into tools that are simple, visual and understandable.
The aim is not to decide for you, but to help you test assumptions, compare scenarios and better understand their consequences.
A transparent method
Each calculator presents its assumptions, formulas, definitions and limitations. When a calculation depends on French rules, Finopact relies wherever possible on public and official sources linked directly from the relevant page.
Tools are reviewed when the rates, thresholds or rules they use change. The reference date shown on each page identifies the framework used for the estimate.
An independent project
Finopact is an independent digital project. Its calculators are available free of charge, without an account and without personalised commercial recommendations.
Results are educational and indicative. They do not replace advice from a qualified professional for an important financial, tax, legal, accounting or property decision.
Privacy by design
Amounts entered into the calculators are processed locally in your browser and are not sent to a Finopact server. Your preferences and favourites can also remain stored only on your device.
This approach lets you use the tools without sharing your personal financial figures with Finopact.
Improving the tools
Finopact is developed progressively through new calculators and improvements to existing tools. The priority remains the same: useful results, a clear interface and explanations that help you understand the calculation.
