Retirement Calculators
Retirement Calculator
Enter your age, what you have saved and what you add each month. The projection uses a single average return, so treat the output as a planning range rather than a forecast.

How this calculator works
Pot = current savings compounded + monthly contributions compounded; Income = Pot × w
- Pot
- the projected balance at your retirement age
- w
- the withdrawal rate you choose for the first year
- Income
- the amount you could draw in year one
A 4% first-year withdrawal, adjusted for inflation afterwards, is a common planning starting point rather than a rule.
Example calculation
Illustrative example — not advice
If you are 35 with $60,000 saved, add $600 a month and earn 6% until 65
- 01You contribute $216,000 over the thirty years on top of the $60,000 already saved.
- 02Compounding at 6% takes the pot to roughly $945,000.
- 03Drawing 4% in the first year gives about $37,800.
Roughly $945,000 at 65, supporting around $3,150 a month before tax.
Small changes to the contribution or the retirement age move the result substantially. This is an educational illustration, not personal financial advice.
Important considerations
- Returns are not smooth; a poor sequence of returns early in retirement matters more than the average.
- The projection is in future dollars and does not adjust for inflation unless you enter a real return.
- Tax treatment of withdrawals varies by account type and is not modelled here.
- Employer contributions, state pensions and other income sources are excluded.

Frequently asked questions
Is a 4% withdrawal rate safe?
It is a widely used starting point derived from historical market data, not a guarantee. Longer retirements, higher fees or a weak first decade of returns all argue for a lower rate.
What return should I assume?
Use a rate you can justify for your actual mix of assets, and test a lower one. Running the calculation at both 4% and 7% shows how sensitive the plan is to that single assumption.
