Formula Used
This calculator uses a general planning formula.
It is not an official court formula.
Combined income = payer income + recipient income.
Payer share = payer income / combined income.
Base child need = higher value of income based need
or minimum need per child multiplied by children.
Special costs = childcare + health + education + other child costs.
Support before cap = payer share × base and special costs
× custody multiplier × need adjustment.
Final monthly estimate = capped support + monthly arrears portion.

Planning Support With Clear Numbers
A pension alimentaire estimate should be practical, transparent, and easy to review.
This calculator gives a planning figure from monthly income, custody style, child costs, and payment limits.
It does not replace a court table or legal advice.
It helps you prepare documents and compare fair scenarios.
Why This Estimate Helps
Support discussions often become emotional.
Clear math can reduce confusion.
You can test income changes, childcare costs, medical premiums, education expenses, and arrears repayments.
The tool also shows the payer income share.
That share explains how combined child costs are divided.
A safety cap protects the result from exceeding the payer ability.
What Inputs Matter Most
Net monthly income is the strongest input.
Enter income after tax and regular payroll deductions.
Essential expenses are used to measure payment capacity.
Custody type changes the multiplier.
Primary care normally increases the transfer.
Shared care lowers it because both homes carry direct child costs.
Existing support is shown as a comparison, not as a legal offset.
Reading The Results
The result panel separates base need, special costs, arrears, cap, and final estimate.
This makes the number easier to check.
Annual support and an indexed next year value are also shown.
Use them for budgeting.
Keep receipts and pay records with your notes.
Courts and mediators often prefer documented figures.
Safe Use Guidelines
Use conservative values when exact numbers are unknown.
Do not hide income.
Do not inflate expenses.
Run more than one scenario when custody or costs may change.
Print or save the download files for discussion.
Confirm local rules before making agreements.
Laws can vary by country, province, state, and court.
A professional review is important before signing anything.
Practical Example
A parent may earn more but share care equally.
Another parent may have higher childcare expenses.
These facts can change the estimate.
The calculator shows how each part affects the final result.
That makes negotiation calmer.
It also helps both sides see whether a proposal is realistic, stable, and affordable over time.
Final Note
Treat every result as a planning guide only.
Local formulas may use official tables, tax credits, benefit rules, or special deductions.
Always compare this estimate with local guidance before final decisions.
FAQs
Is this an official pension alimentaire calculator?
No. It is a planning tool. Local courts may use official tables, tax rules, and special deductions. Use the result for preparation only.
Can this calculator handle shared custody?
Yes. Select shared care in the custody field. The calculator applies a lower multiplier because both homes usually carry direct child costs.
What income should I enter?
Enter net monthly income after taxes and regular deductions. Use current, honest values. Wrong income data can make the estimate unreliable.
Are childcare and health costs included?
Yes. The form includes childcare, health, education, and other recurring child costs. These are shared using the payer income share.
What does the ability cap mean?
The cap limits estimated support to a percentage of available payer income. It helps avoid an amount beyond practical payment capacity.
Does existing support reduce the result?
Existing support is shown as a comparison. The calculator displays the difference between the estimate and the current order or agreement.
Can I download my result?
Yes. Use the CSV button for spreadsheet records. Use the PDF button for a simple printable summary of the calculation.
Should I use this before mediation?
Yes, it can help you prepare. Bring income proof, receipts, custody details, and the downloaded estimate to support informed discussion.
