What is a plan de pensiones?

A plan de pensiones is a private, voluntary retirement investment wrapper in Spain. Contributions reduce your IRPF taxable base (within annual limits), the fund grows tax-deferred, and the whole payout is taxed as employment income when you withdraw. It is separate from — and additional to — the public Seguridad Social pension, which this tool does not calculate.

How this calculator works

Enter your balance, contributions, horizon, expected return and fee for a base projection. Open the advanced options to add your plan type, current IRPF marginal rate, the effective tax rate you expect at withdrawal (as a lump sum or as an income stream), and the fee and capital-gains rate of an indexed alternative. The model compounds each yearly flow net of fees, applies the deductible limits from the Spanish rule-pack, estimates your entry-side tax saving at your own marginal rate, taxes the withdrawal at your assumed effective rate, and taxes the alternative only on its gain — then reports the net advantage in euros and the two break-even points.

Worked Example

A €20,000 plan with €1,500/year personal contributions over 25 years at 5% gross and a 1% fee grows to about €117,180 gross. Deducting €1,500/year at a 37% marginal rate saves roughly €13,875 over the period; reinvested at 5% that saving is worth about €23,966 net. Taxing the lump-sum withdrawal at an assumed 30% effective rate leaves about €105,992 net, versus roughly €120,255 net for an indexed alternative fed the same gross contributions and taxed only on its gain — here the low-cost fund is ahead. The break-even withdrawal rate is about 17.8%: below it the plan wins, above it the fund does. These exit and marginal rates are your assumptions, not statutory brackets.

Key Insight

A plan de pensiones is a bet that your marginal rate today is meaningfully higher than your effective rate when you withdraw. The deduction is a genuine, immediate benefit at your marginal rate, and — crucially — it only pays off if you actually reinvest it or if it lets you invest more for the same net cost. The two things that quietly decide the outcome are the fee gap versus a cheap index fund and the exit tax: a plan de pensiones is taxed as ordinary employment income on the way out (not as savings income), so a large lump sum can land in high brackets. This tool makes both levers explicit with a break-even exit rate and a break-even fee differential, and it never applies a single marginal rate to your whole withdrawal as if IRPF were flat.

The 2022 cut: only €1,500/year in individual plans

Until 2020, the deduction limit for individual pension plans was €8,000/year. The 2021 and 2022 Budget Laws cut it sharply to €1,500/year from 2022 (still in force in 2026). The change turned individual plans into a far less attractive tax-saving tool — especially compared with neighbouring European countries.

The government's approach was to redirect supplementary saving toward employer plans. The combined individual + employer ceiling can reach €10,000/year (€1,500 + €8,500) when the extra €8,500 comes from employment-plan contributions, and the self-employed can use Simplified Employment Plans (PPES). All of these limits live in the versioned rule-pack behind this tool, not in the page text.

Marginal on the way in, effective on the way out

Contributions reduce your IRPF taxable base in the contribution year, saving tax at your marginal rate. Withdrawals are taxed as employment income (rendimientos del trabajo), not savings income — so the rate that matters at the end is your effective rate across the whole withdrawal, which depends on the amount, the form (lump sum vs income stream) and your other income that year.

This tool does not apply your top marginal rate to the entire withdrawal as if IRPF were flat. Instead it asks you for the effective rate you expect under each withdrawal form and applies that. A retiree drawing a €100,000 lump sum does not pay their marginal rate on all €100,000; the effective rate is lower and is exactly the number you control here.

The fee gap usually decides it

The entry-side deduction is real, but a plan de pensiones charging 1.0-1.5% a year against an index fund charging 0.2-0.4% gives back a large share of that advantage over decades. The break-even fee differential in this tool shows how much more expensive the plan can be before the deduction is fully eroded.

Since 2025, contributions at least 10 years old can be withdrawn without a specific contingency, which softens the old illiquidity argument. But the core decision stays the same: the plan wins when your exit effective rate is clearly below your contribution marginal rate and the fee gap is small.

Individual vs employment vs PPES

The deductible ceiling depends on the plan type. All limits come from the versioned rule-pack, not from this text.

Illustrative annual tax saving by marginal rate (2026)

Immediate IRPF saving = deductible contribution × the marginal rate you enter. These are illustrative examples at sample marginal rates, not uniform national brackets: IRPF is progressive and partly regional (it varies by Comunidad Autónoma), the deduction is capped at 30% of net income, and the saving is a marginal estimate that is partly repaid on withdrawal.

Only an employment plan reaches the €10,000 combined ceiling. Generated from the rule-pack limits — the same numbers appear on the Spanish page.

Methodology & model

• Timing convention: contributions are made at the start of each year (annuity-due) and the initial capital sits at the start of year 1; both earn a full year of growth in year 1.
• Fees: netRate = (1 + gross return) × (1 − fee) − 1, applied each year.
• Deductibility: the minimum of the applicable contribution, the plan-type monetary limit, and 30% of net income (when supplied); without income the result is partial.
• Marginal vs effective: the entry-side saving uses your marginal rate; the withdrawal uses the effective rate you supply (lump sum and income), never the top marginal rate on the whole balance.
• Indexed alternative: compounds the flows net of fee and taxes only the gain at the rate you enter, never the contributed capital.
• Comparison basis: “same gross” invests the same gross contribution; “same net cost” invests the after-deduction net cost.
• Model limits: it does not compute real progressive IRPF or regional IRPF; the rates are assumptions. Not tax advice.

The model projects the plan de pensiones balance net of the annual fee (netRate = (1+grossRate)×(1-feeRate)-1), applies the deductible-contribution limits from a versioned, source-backed Spanish rule-pack (individual limit, 30%-of-net-income cap, employment-plan increase, PPES limit), estimates the entry-side saving at the user's own marginal rate, taxes the withdrawal under a user-supplied effective rate (lump sum and income stream) and compares the whole thing with a low-cost indexed alternative that is taxed only on its gain. Every fiscal limit comes from the rule-pack, not from code; exit and marginal rates are the user's assumptions, not statutory brackets.
