Retirement calculator

Estimate your pension and the capital you will have at retirement, compare early, normal, and late retirement, and see whether the projected income covers your expenses.

  1. 1

    Understand what the calculator does

    The calculator brings together two sources of retirement income: the pension you will receive and an annual withdrawal from the capital you will have built up. It adds them and compares the total against the expenses you expect.

    TipIt is a simplified estimate, not your country's official calculation. Use it to compare scenarios — always confirm the figures with your country's social security body.

  2. 2

    Enter your details

    Start with your current age, current contribution years, and average salary. The estimate also adds the years remaining until retirement.

    TipThere is no save button. After changing a value, you see Saving and Saved. Invalid values are not stored.

  3. 3

    Compare the three retirement ages

    Switch between Early, Normal, and Late and watch the result change immediately. Retiring earlier cuts a percentage from the pension; later adds a bonus.

    TipAll three ages are editable. Enter your own country's rather than accepting the defaults — the calculator assumes no particular system.

  4. 4

    Enter what you already have

    Fill in the savings, investments, and retirement savings (PPR) you have today. The projection uses nominal return and inflation to show the result in today's money.

    TipThese fields start at zero and are not filled in from your accounts — enter the figures by hand.

  5. 5

    Read the summary

    The dark card sums it all up: the estimated pension, the withdrawal from savings, the monthly total, and your projected expenses. At the bottom, a banner says whether the month closes in surplus or deficit.

    TipIf projected contribution years stay below the minimum and you set a minimum pension above zero, a note appears when that floor is applied.

  6. 6

    Adjust the formula to your country

    Under Calculation formula (advanced) sit all the rules, so you can match the system you pay into:

    • Accrual rate — how much of your salary counts for each contribution year.
    • Max accrual years — the point beyond which extra years stop counting.
    • Min contribution years — below this you only qualify for the minimum pension.
    • Minimum pension — the guaranteed floor. Zero by default.
    • Early penalty and late bonus — what you lose or gain by retiring off the normal age.
    • Safe withdrawal rate — the slice of capital you take each year.

    TipThe minimum pension defaults to zero on purpose: any other figure would belong to one specific country and would mislead everyone outside it.

  7. 7

    See the projected capital

    The Wealth Projection card shows retirement capital in today's money. Below it are the years remaining, projected contribution years, real return, and withdrawal rate.

  8. 8

    Export the scenario

    Export PDF produces a report with the inputs you entered and the results. It is useful for keeping a scenario before you change it, or for taking to a conversation with an adviser.

  9. 9

    Use the calculator on mobile

    On mobile, the page has its own layout: the monthly balance at retirement sits in the coloured header, followed by the summary card, projected wealth, and the export button. Unlike the other pages, the fields you fill in stay visible below rather than hidden in a separate form — here, adjusting values is the task itself, not a secondary action.

    TipAfter changing a value, scroll back up to see the updated result in the header.
