Retirement Savings Calculator
Estimate how much your retirement savings could grow before your chosen retirement age. Enter your current savings, monthly contribution and assumed return, then add inflation to compare the future balance with its purchasing power today. Use your own currency and assumptions; no national pension ages or rates are preloaded.
Please check your inputs — retirement age must be greater than current age, and inflation cannot be negative.

How to use this retirement planning calculator
- Enter your current age and planned retirement age to set the saving period.
- Add the balance already saved and the amount you expect to contribute each month.
- Enter an assumed annual return. Run a 0% case as a contributions-only comparison.
- Add an inflation assumption to see the result in today’s money.
- Compare the projected balance, contributions and growth before changing one input at a time.
How the retirement projection is calculated
For n months, monthly rate r and end-of-month contribution C, the future balance is P × (1 + r)n + C × ((1 + r)n − 1) ÷ r. P is your current savings, r is the annual percentage divided by 100 and 12, and n is the age gap multiplied by 12, rounded to a whole month. At a 0% return the balance is P + C × n.
The model compounds monthly, keeps contributions fixed and uses one constant return throughout. Inflation-adjusted balance = future balance ÷ (1 + annual inflation rate)years. Your actual investment returns will not follow a smooth monthly path.
Worked example: retiring at 65
A person aged 40 with 40,000 saved and contributions of 300 a month has 25 years to save before age 65. The table uses fictional constant returns, 2% annual inflation, monthly compounding and deposits at each month’s end. All amounts use the same currency.
| Assumed annual return | Future balance | In today’s money |
|---|---|---|
| 0% | 130,000.00 | 79,239.01 |
| 2% | 182,567.75 | 111,280.68 |
| 4% | 262,789.47 | 160,178.29 |
| 6% | 386,496.98 | 235,581.84 |
Contributions total 130,000 in every row: 40,000 already saved plus 90,000 in new deposits. The difference comes from the assumed growth. These scenarios are examples, not forecasts or recommended returns.
When to use this tool
Use this for workplace pension check-ins, private pension projections, and “am I on track?” scenarios.
Key Features & Benefits of This Retirement Calculator
- Savings and monthly contributions together — your current balance and your monthly deposits are both grown month by month until retirement age.
- Balance, contributions and growth — see the estimated balance at retirement, your total contributions (current savings plus monthly deposits) and the growth.
- Test cautious assumptions — run a lower return as well as your best guess; a 0% return shows what contributions alone reach.
- Balance in today’s money — enter an expected inflation rate to see what the retirement balance would be worth in today’s purchasing power (€160,178.29 at 2% in the example).
- Instant, free and private — runs entirely in your browser, no sign-up, nothing stored.
Good to know
State pension ages and entitlement rules vary by country. Combine this investment-style projection with official pension forecasts from your national authority. Revisit the projection when income, contribution rate or planned retirement age changes.
Retirement Calculator — FAQs
What inputs does a retirement calculator need?
Typical inputs are current age, planned retirement age, current savings, monthly contribution, expected annual return and sometimes expected inflation or withdrawal rate. This tool uses all of these except the withdrawal rate to project a nest egg.
Is the projected amount guaranteed?
No. Returns vary year to year. The result is an illustration based on a constant assumed rate, not a promise of future performance.
Should I include Social Security or pensions?
If you have reliable expected benefits, you can treat them as reducing the savings target rather than as part of this investment projection. Model them separately for a fuller picture.
Does this adjust for inflation?
Yes, if you enter an expected inflation rate. The main result is in future money. The balance in today’s money divides it by (1 + inflation) for every year until retirement. If you leave inflation empty, both figures are the same.
Is this a pension eligibility or retirement age calculator?
No. You choose the retirement age and saving assumptions. It does not calculate statutory pension age, benefits or eligibility for any country.
Why does inflation reduce my retirement balance?
Inflation does not subtract from the nominal balance shown here. It reduces what that future sum could buy, so the calculator also expresses the result in today’s purchasing power.

- FCA InvestSmart: Risk and returns: the value of an investment can go down as well as up, so returns are not always positive.
How much do I need to retire?
A projected savings pot is only one part of that question. This calculator does not turn the balance into a lifetime income, calculate an official pension or decide whether you can retire. Compare expected spending with income from pensions and other sources, then consider how long withdrawals may need to last.
For a savings target, use the Savings Calculator. To compare deposits and compounding frequencies, use the Compound Interest Calculator. The SEC’s Investor.gov compound interest calculator provides another educational growth model.
