Disclaimer

Results are estimates for educational purposes only. They do not constitute financial advice. Consult a qualified professional before making financial decisions.

2,500 monthly target at 4% SWR = 750,000 pot needed (30,000 annually / 4%). Higher target at same rate = larger pot. Lower SWR at same target = larger pot for safety.

A worked example

Try the defaults: target monthly income of 2,500, withdrawal rate of 4%. The tool returns 750,000.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Target Monthly Income and Withdrawal Rate. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

Why the number matters

Saving without a target is like driving without a destination — you'll make progress, but you won't know when you've arrived. This tool gives you a concrete figure to work toward, which is the first step in turning a vague intention into an actual plan.

What this doesn't capture

The calculation assumes a steady savings rate and a stable interest rate. Real saving journeys include emergencies, windfalls, and rate changes — especially in easy-access products. The figure is a direction of travel, not a guarantee.

What to calculate alongside this

One figure by itself is fragile. The retirement pot size calculator, the pension drawdown rate calculator, and the pension income projection calculator cover adjacent ground — the answer to any one of them changes how you read the output from this tool. Worth a few minutes each, honestly.

Example Scenario

Frequently Asked Questions

Include state pension?
Subtract state pension from target first. This tool covers the shortfall to be funded by your private pot.
Safer rate?
3-3.5% for long retirement (30+ years). 4% classic Bengen for 25-30 years.
Does pot last forever?
At sustainable SWR, pot typically lasts 30+ years or grows. Higher rates may exhaust it.
Inflation?
SWR implicitly accounts for inflation-adjusted withdrawals. Target today's purchasing power.
