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 does this calculator adjust for?+
It projects how much a given amount of spending today will cost in future years after applying a chosen inflation rate, or conversely, what today's dollars are worth in the future. It's used to see how a fixed budget loses purchasing power over a long retirement.
Why does even a 'low' inflation rate matter so much over 20-30 years?+
Inflation compounds — at just 3% per year, prices roughly double in 24 years, meaning a budget that covers your needs today would need to be roughly twice as large decades into retirement just to buy the same goods and services. Small annual rates produce large cumulative effects over typical retirement lengths.
Should I use historical average inflation or the current rate?+
For long-term retirement planning, most planners use a long-run historical average (often around 2-3% in stable, developed economies) rather than a recent spike or dip, since retirement projections span decades and a single year's rate is a poor predictor of the average over that time.
Does this calculation assume all my expenses inflate at the same rate?+
Typically yes, using one blended rate, but real-world costs diverge — healthcare and housing have historically outpaced general inflation in many markets, while some consumer goods have lagged. For a more accurate projection, consider applying a higher rate specifically to healthcare-heavy budgets.
How is this different from a real-return-after-inflation calculation?+
Inflation-adjusted spending focuses on future costs of a fixed basket of goods (the expense side), while real return after inflation focuses on what your portfolio's growth rate is worth net of inflation (the investment side) — both use the same inflation concept but apply it to different halves of a retirement plan.
