How MonCalculateur Immobilier fits into the workflow
Model the loan
Enter the borrowed capital, term, nominal rate, and insurance rate to see your monthly payment, cumulative interest, and indicative total cost.
Check what you can afford
Estimate your borrowing capacity from income and recurring charges against the indicative 35% HCSF debt-ratio ceiling.
Compare and decide
Add notary fees, run a rental-yield or PTZ estimate, and put two fixed-rate offers side by side before you commit to a meeting.

Questions
Questions people ask before downloading MonCalculateur Immobilier
What can the app simulate?
Monthly mortgage payments and total cost, borrowing capacity, notary fees, rental yield, an indicative PTZ by zone, and a comparison of two fixed-rate loan offers.
Does it work offline?
Yes. The app has a full offline mode and no data is sent for the calculation. Your simulations stay on your device.
Is this a substitute for a broker or notary?
No. It is an informational simulation tool. Results depend strictly on the parameters you enter and must be verified with a registered IOBSP broker, a bank, a notary, an ADIL adviser, or a tax professional before any decision.
Beyond the app
Need something more tailored than MonCalculateur Immobilier?
If you are a broker, agency, or lender that needs this kind of simulation inside a larger client or origination workflow, I can build a tailored calculator and comparison tool around your exact products and process.
- Custom mortgage, fee, and yield calculators for your clients
- Multi-offer comparison with your own ranking logic
- A bridge from a single simulation to a client-facing portal
Bigger workflow
If this app opens up a bigger problem
The app may solve a concrete job immediately. If it exposes a larger operational, web, or content problem behind it, these are the closest practical routes.
Web platforms
If this direction points toward a portal, stronger web layer, SEO surface area, or client-facing interface, this is the closest next route.
Operational systems
If the workflow behind the app reveals manual steps, approval layers, tool sprawl, or operational debt, this is where it becomes a real system.
