SIPP Calculator

Pay in net, the government tops it up. See your pension pot, the 25% tax-free lump sum, and the relief you can reclaim.

📖 About this tool

What it does

Grosses up your net contribution with 20% basic-rate relief, compounds the pot to retirement, and shows the 25% tax-free lump sum plus the taxable remainder. Higher/additional-rate relief reclaimed separately is shown too.

Who this helps

UK workers and the self-employed building a private pension, especially higher-rate taxpayers for whom the relief is most valuable.

What it doesn't do

Assumes basic-rate relief at source and a flat return. Does not model the annual allowance (£60k), tapering, or the lump-sum allowance cap.
