France PER Calculator: Plan d'Épargne Retraite Growth

Estimate what a French PER (plan d'épargne retraite) grows to from regular contributions — the retirement savings plan introduced in 2019 that lets you deduct contributions from taxable income now and draw the money as capital or income at retirement.

Investment Details
Your current PER balance (or transferred-in amount). Start at 0 if you're opening one.
A PER's euro fund (fonds en euros) is capital-guaranteed with a lower return; unit-linked supports (unités de compte) target higher returns with risk. Use a rate matching your allocation.
What you pay in each month. Voluntary contributions are deductible from taxable income up to an annual ceiling (a percentage of professional income, with a floor and cap); this calculator doesn't enforce it.

How This Calculator Works

Enter your current PER balance, monthly contribution, the return you expect, and the years to retirement. The calculator compounds the balance monthly and shows the projected value and the growth. The PER's appeal is the upfront deduction: voluntary contributions reduce your taxable income (within a ceiling), the savings grow tax-deferred, and the money is locked until retirement (with a few exceptions, notably buying your main home).

The Formula

Future Value with Regular Contributions

FV = P(1 + r)^n + PMT · ((1 + r)^n − 1) / r

P = starting amount, PMT = monthly contribution, r = monthly rate (annual ÷ 12), n = number of months

Worked Example

€300 a month for 25 years at 4% grows to about €154,239, with roughly €64,239 of that being growth. The PER (plan d'épargne retraite) replaced older French retirement products (PERP, Madelin) from 2019, unifying them into one flexible plan. Its headline benefit is tax: voluntary contributions are deductible from your taxable income up to an annual ceiling, so a high-rate taxpayer gets a substantial immediate saving. The trade-off is that funds are locked until retirement — though you can withdraw early to buy your primary residence, or in hardship cases — and the deducted contributions are taxed when you draw them.

Key Insight

The PER is the centrepiece of France's reformed retirement saving, and the deduction-now/taxed-later logic is key. The upfront benefit: voluntary contributions (versements volontaires) are deductible from your taxable income, up to an annual ceiling (broadly a percentage of professional income, between a floor and a cap, with unused allowance carryforward), so the real value depends on your marginal tax rate — a 41% taxpayer effectively gets the state to fund a large part of the contribution, while a low-rate taxpayer benefits less and might instead opt out of the deduction for lighter taxation at exit. The plan grows tax-deferred and you choose the investment mix: a capital-guaranteed fonds en euros and/or market-linked unités de compte, often via a managed 'gestion pilotée' glide path that de-risks as retirement nears. At retirement you have flexibility the old products lacked: you can take the PER as a lump sum (capital), as a lifetime annuity (rente), or a mix. The catch — and what this calculator omits — is exit taxation: if you deducted contributions going in, then at withdrawal the contributions portion is taxed as income and the gains are taxed too (the precise treatment differs for lump sum vs annuity); if you opted not to deduct, the exit tax is lighter. Liquidity is restricted: the money is locked until retirement, with defined early-exit cases — most notably purchasing your primary residence, plus hardship events (disability, death of spouse, end of unemployment rights, over-indebtedness). Fees vary widely and compound over decades, so low-cost contracts matter. This calculator gives a gross, constant-return projection and omits the contribution ceiling, fees and exit tax; in practice deduct contributions if your rate is high, mind the annual ceiling, favour low-cost investments, and plan the lump-sum/annuity split for tax efficiency at retirement.

Le plafond de déduction : 10% du revenu, au maximum €35,194 en 2026

Le plafond annuel de déductibilité des versements PER est calculé sur les revenus de l'année précédente. Pour un salarié en 2026, le plafond est de 10% du revenu professionnel net 2025 (après abattement de 10% ou frais réels), avec un minimum garanti de €4,637 (10% du PASS 2025) et un maximum de €37,094 (8 PASS × 10%, où PASS 2026 = €46,368).

Pour les indépendants (TNS), le plafond est plus généreux : 10% du bénéfice imposable + 15% du bénéfice entre 1 et 8 PASS, soit jusqu'à environ €87,000 par an. Cette différence rend le PER particulièrement intéressant pour les professions libérales et chefs d'entreprise.

Critique : le plafond non utilisé d'une année se reporte pendant 3 ans. Vous pouvez aussi mutualiser le plafond avec votre conjoint (cocher l'option dans la déclaration 2042). Vérifiez le plafond non utilisé dans votre avis d'imposition (case 'Plafond pour les cotisations versées en 2026').

L'arbitrage déduction maintenant vs imposition à la sortie

Le PER est un produit fiscalement neutre dans le temps si vos taux marginaux d'imposition restent identiques entrée/sortie : ce que vous économisez à l'entrée, vous le paierez à la sortie. L'avantage réel apparaît quand le taux à la retraite sera plus bas qu'aujourd'hui — situation typique des cadres en fin de carrière.

Exemple concret : un cadre en tranche marginale 41% (revenu imposable >€83k/personne) qui verse €5,000 sur son PER économise €2,050 d'impôt immédiat. Si à la retraite il est en tranche 30%, le retrait des €5,000 (+ intérêts) sera taxé à 30% — soit un gain net de 11 points × €5,000 = €550 sur le seul versement initial, plus l'effet capitalisation tax-free pendant la phase d'épargne.

Pour les contribuables en tranches 11% ou 0%, le bénéfice de la déduction est faible voire nul. Dans ce cas, il vaut mieux NE PAS opter pour la déductibilité (option formulée à chaque versement) — les retraits seront alors moins fiscalisés (seuls les gains sont taxés au PFU 30%, et les versements ressortent en franchise).

Sortie : capital, rente ou panaché — le choix tactique

À la retraite (62 ans minimum, sauf cas spéciaux), vous choisissez entre trois modalités de sortie : capital (lump sum), rente viagère, ou mélange des deux. Cette flexibilité distingue le PER des anciens PERP/Madelin qui imposaient la sortie en rente.

Sortie en capital : si vous avez déduit les versements, la part capital correspondant aux versements est imposée au barème de l'IR (sans étalement, ce qui peut être brutal sur une grosse somme), et la part plus-values est soumise au PFU 30%. Si vous n'aviez pas déduit, seuls les gains sont taxés au PFU 30% — bien plus favorable.

Sortie en rente viagère : imposée au régime des rentes viagères à titre onéreux ou gratuit selon que vous aviez déduit ou non. Avec déduction, la rente est imposée à l'IR (avec abattement de 10% si applicable). Sans déduction, seule une fraction est imposable selon l'âge à la liquidation (par exemple 40% si liquidation à 65 ans). Cas particulier intéressant : sortie anticipée pour résidence principale (achat du logement principal) — autorisée même sans atteindre l'âge de retraite.

Économie d'impôt par versement PER selon la tranche marginale

Économie d'impôt immédiate au titre du versement annuel sur le PER, par tranche marginale d'imposition. Ne pas oublier que cette économie sera reprise à la sortie selon votre tranche d'imposition à la retraite.

Tranche marginale (TMI)€2,000 versés€5,000 versés€10,000 versés€20,000 versés
11% (revenus ~€11k-€27k)€220€550€1,100€2,200
30% (revenus ~€27k-€78k)€600€1,500€3,000€6,000
41% (revenus ~€78k-€168k)€820€2,050€4,100€8,200
45% (revenus >€168k)€900€2,250€4,500€9,000

À cette économie immédiate, ajouter les rendements tax-free pendant la phase d'épargne. À la sortie, l'imposition reprendra une partie de l'avantage selon le taux marginal à la retraite. Plafond annuel 2026 : ~€37,094 maximum pour les salariés.

Frequently Asked Questions

How is PER growth calculated?

Your balance and monthly contributions compound at the expected return (annual rate ÷ 12 per month). €300/month for 25 years at 4% grows to about €154,239, with roughly €64,239 of growth — before fees, and before the tax due when you draw the PER at retirement.

What is a PER?

The plan d'épargne retraite — France's unified retirement savings plan introduced in 2019, replacing older products like the PERP and Madelin. Voluntary contributions are deductible from taxable income up to a ceiling, the savings grow tax-deferred, and you draw them as capital, an annuity, or both at retirement.

What's the tax benefit of a PER?

Voluntary contributions are deductible from your taxable income up to an annual ceiling, so the saving depends on your marginal rate — most valuable for high earners. The catch is that deducted contributions are taxed as income when you withdraw at retirement, so it's a deduction-now, taxed-later arrangement.

When can I access a PER?

Generally only at retirement — the funds are locked until then. The main exceptions are buying your primary residence (you can withdraw early for that) and hardship cases such as disability, death of a spouse, end of unemployment rights, or over-indebtedness. Otherwise treat the PER as retirement money.

How is a PER different from an assurance vie?

A PER offers an upfront contribution deduction but locks the money until retirement and taxes it on the way out; an assurance vie gives no deduction but stays accessible and is very tax-efficient on gains after eight years, with inheritance advantages. Many French savers use both, for different goals.

The future value compounds a starting balance plus a fixed monthly contribution at the annual return, compounded monthly. It assumes a constant return and end-of-month deposits, and does not enforce the annual deductible-contribution ceiling, model fees, or compute the tax due when the PER is drawn at retirement.
