Note
This is not financial advice. It is a simplified model: it applies the displayed standard formula to the figures you entered, assumes a single constant rate for every year, and ignores taxes, fees, sequence-of-returns risk, health costs, longevity risk and any country's specific pension, benefit or minimum-distribution rules. Real returns can be negative and real retirements rarely follow a smooth curve. Check the assumptions and consult a licensed adviser before acting on any figure.

What is the difference between nominal and real return?+
Nominal return is the raw percentage gain your portfolio shows before accounting for inflation; real return subtracts out the effect of inflation to show how much actual purchasing power your money gained. A 7% nominal return with 3% inflation leaves roughly 4% of real growth in what you can actually buy.
Why isn't real return simply nominal minus inflation?+
That's a common and close approximation, but the precise formula is (1 + nominal) / (1 + inflation) - 1, which compounds the two rates rather than just subtracting them; the difference is small at low rates but grows more noticeable at higher rates.
Why does real return matter more than nominal return for retirement planning?+
Because your future spending needs are in real terms — you care about buying groceries and paying rent, not about a percentage on a statement — so a retirement plan built only on nominal returns without netting out inflation will systematically overstate how much your money can actually buy in the future.
Can real return be negative even if nominal return is positive?+
Yes — if inflation exceeds your nominal return (for example a 2% nominal gain during a year with 5% inflation), your purchasing power actually shrank even though the account balance grew, which is a common risk for very conservative, cash-heavy portfolios during inflationary periods.
What inflation rate should I use in this calculation?+
For long-term projections, a long-run historical average (commonly 2-3% in stable economies) is more reliable than a single recent year's rate, since short-term inflation spikes or dips are poor predictors of the multi-decade average relevant to retirement planning.
