A projection, not a forecast. Investment returns vary, and tax treatment of pensions depends on your country.
How the retirement calculation works
Your pot at retirement is the future value of today's savings plus every contribution made until you stop working, grown at an assumed annual return. The withdrawal rate then converts the pot into income.
The 4% rule is a widely used starting point: withdraw 4% of the pot in year one and increase with inflation. It is a planning heuristic from US historical data, not a guarantee.
Showing income in today's money matters because inflation erodes purchasing power. A dollar in thirty years buys considerably less than a dollar now.
Worked example
Age 35, retiring at 65, $40,000 saved, $500 a month, 6.5% return.
- →360 monthly contributions
- →Pot ≈ $40,000 × 6.6 + $500 × annuity factor
- →Pot ≈ $860,000
Answer: A pot near $860,000 supporting about $34,000 a year at a 4% withdrawal rate.
Retirement FAQs
What return should I assume?
A globally diversified portfolio has historically returned roughly 5–7% a year after inflation over long periods, but with large swings. Model a lower figure too, so the plan survives a poor decade.
Does the state pension count?
This tool only models your own savings. Any state or employer pension is additional income — subtract it from your target to work out how much the pot needs to cover.
Why does a 1% lower return matter so much?
Because it compounds over decades. On a 30-year horizon, one percentage point can change the final pot by 20% or more.
