Tax-Free Lump Sum (25%)
Private Pension Income (4% rule)
State Pension Income
Total Retirement Income (after tax)
How I calculate your income
- 25% taken as a tax-free lump sum
- 4% sustainable withdrawal rate on the remaining 75% fund
- UK income tax bands applied to total retirement income
- State Pension included when selected (paid from State Pension age)
- No contributions after retirement
Important Note:
The 4% withdrawal rate is a common rule of thumb for sustainable income, not a guarantee. Actual longevity, investment performance, tax changes, and personal circumstances will affect outcomes.
Tax Relief Bands
20% on income up to £50,270
40% on income between £50,270 and £125,140
45% above £125,140
Tax relief reduces the cost of your contributions by your marginal tax rate.
How tax relief works
Enter the gross amount credited to your pension each month. If you pay from take-home pay with basic-rate relief at source, your estimated net cost at a 20% marginal rate is about £0 per month.
💡 You don't pay the full contribution yourself. The government tops it up, so your pension grows faster than the amount you personally pay.
Key Points
