How retirement planning works
The calculator separates accumulation and withdrawal phases. Contributions and withdrawals occur at each month’s end after the assumed monthly return. Desired income is entered in today’s purchasing power; its nominal amount rises with inflation before and during retirement. Planning age is only a chosen horizon. Public or employer pensions, taxes and fees are excluded.
Model limits
- ✓Returns and inflation are constant assumptions; actual market returns fluctuate.
- ✓This models freely assumed savings, not a public pension system.
- ✓It is neither investment advice nor a pension promise and does not use the 4% rule.
Frequently asked questions
How does the retirement calculator work?
It simulates monthly accumulation, then inflation-adjusted withdrawals through the planning age.
How is capital accumulated?
Current capital earns its monthly return before the end-of-month contribution is added.
Why enter income in today’s purchasing power?
It makes today’s income goal comparable with inflation-adjusted retirement amounts.
How is inflation handled?
Annual inflation becomes an equivalent monthly rate that raises income before and during retirement.
What is required retirement capital?
It is the present value at retirement of all planned inflation-growing monthly withdrawals.
How is the possible withdrawal calculated?
It follows mathematically from capital, return, inflation and retirement duration.
What happens at 0% return?
The model remains valid; accumulation then grows only through contributions.
Can returns be negative?
Yes, provided each annual return is greater than −100%.
What is planning age?
It is your chosen funding horizon, not a medical forecast.
Is a public pension included?
No. Desired income is funded entirely from the simulated capital.
Are taxes included?
No. All results are before tax.
Are fees included?
No. Your return assumption is applied directly.
Does this use the 4% rule?
No. Withdrawal is calculated from your inputs.
Is the result guaranteed?
No. It is a mathematical model with constant assumptions.
How long will my capital last?
Capital first receives the assumed monthly return, then the withdrawal is deducted until a full withdrawal is no longer possible.
Can I set a desired ending balance?
Yes. The visible ending balance is included when calculating withdrawals and required retirement capital.
How do rising withdrawals work?
The annual increase applies in twelve-month steps. It is a scenario assumption, not automatic inflation.
Can I enter pension income?
You may enter an amount you already expect as other income. FreeTools does not calculate government pensions.
