Retirement Savings

Your pot at retirement and yearly income

Pot at retirement476,645
Of which contributions173,600
Yearly income at 4% withdrawal19,066

How it works

  • Growth is compounded monthly at your expected yearly return.
  • The 4% rule: withdrawing 4% a year has historically lasted about 30 years.
  • Starting 10 years earlier can nearly double the final pot.
  • Results are before tax and inflation — they are projections, not guarantees.

Worked example: age 35, 20,000 saved, 400 a month, 5%

  1. 132 years = 384 months.
  2. 2Existing savings grow to ≈ 98,000.
  3. 3Contributions grow to ≈ 386,000.

≈ 484,000 pot — about 19,400 a year at 4%

Pot at 67 with 400 a month at 5% (no starting savings)

Frequently asked questions

How much do I need to retire?

A common rule of thumb is 25 times your desired yearly spending, which matches the 4% withdrawal rule.

What return should I assume?

4–6% a year is a moderate long-term assumption for a mixed portfolio; use lower figures to be cautious.

Does this include state pension?

No. Add any state or workplace pension to the yearly income figure separately.
