What is the SIPP Contribution Calculator?
The SIPP Contribution Calculator helps you calculate your Self-Invested Personal Pension (SIPP) contributions and optimise your tax relief. It shows how much tax relief you’ll receive, tracks your annual allowance usage (£60,000), and projects your pot growth to retirement. The calculator accounts for basic rate relief (automatically added), additional relief for higher/additional rate taxpayers, and carry-forward allowances.
How the Calculator Works?
Enter your annual income, net contribution amount, and marginal tax rate. The calculator automatically calculates the 20% basic rate relief that the government adds to your contribution. If you’re a higher or additional rate taxpayer, it shows the additional relief you can claim through self-assessment. It also tracks your annual allowance usage and shows how your SIPP pot will grow over time.
The calculator uses relief at source, which is the most common method for SIPPs. You pay your net contribution, and the government automatically adds 20% basic rate relief. Higher and additional rate taxpayers can then claim additional relief through their self-assessment tax return.
Step One: Enter Your Profile
Enter your annual income (used to check annual allowance limits), current age, retirement age, and current SIPP pot balance (if any).
Step Two: Set Your Contribution
Enter your net contribution (the amount you pay into your SIPP). Select your marginal tax rate (20%, 40%, or 45%) to calculate additional tax relief. Optionally, enter any carry-forward allowance from previous years.
Step Three: Set Investment Assumptions
Set your expected annual investment return and annual fee. These are used to project your pot growth to retirement age.
Disclaimer: This calculator provides illustrative calculations only and does not constitute financial or tax advice. Tax relief calculations are estimates based on simplified assumptions. Additional relief for higher/additional rate taxpayers must be claimed through self-assessment. Annual allowance limits apply, and contributions exceeding the allowance may face tax charges. Always consult a qualified financial advisor for SIPP and tax planning.

What is the SIPP Contribution Calculator?
It is a UK-specific tool that calculates your Self-Invested Personal Pension (SIPP) contributions, tax relief, and annual allowance usage. It shows how much tax relief you’ll receive, tracks your annual allowance (£60,000), and projects your pot growth to retirement.
What is a SIPP?
A SIPP (Self-Invested Personal Pension) is a type of personal pension that gives you more control over your investments. You can choose from a wide range of investments, including stocks, funds, and commercial property.
How does SIPP tax relief work?
SIPP contributions receive tax relief at source. You pay your net contribution, and the government automatically adds 20% basic rate relief. Higher and additional rate taxpayers can claim additional relief through self-assessment.
What is the annual allowance?
The annual allowance is the maximum amount you can contribute to your pension each year and still receive tax relief. For 2024/25, it’s £60,000 or 100% of your earnings, whichever is lower.
Can I use carry-forward?
Yes. If you haven’t used your full annual allowance in the previous 3 years, you can carry forward the unused amount. The calculator allows you to enter your carry-forward amount to see your total available allowance.
How much tax relief will I get?
Basic rate taxpayers receive 20% relief automatically. Higher rate taxpayers (40%) can claim an additional 20% through self-assessment. Additional rate taxpayers (45%) can claim an additional 25% through self-assessment.
What if I exceed the annual allowance?
If you exceed the annual allowance, you may face an annual allowance charge. The charge is added to your income tax bill. The calculator will warn you if your contribution exceeds the allowance.
Can I contribute more than my earnings?
No. The annual allowance is limited to 100% of your earnings, even if the standard allowance is £60,000. The calculator uses your annual income to check this limit.
How do I claim additional tax relief?
Higher and additional rate taxpayers must claim additional relief through their self-assessment tax return. The calculator shows how much additional relief you can claim, but you must submit a tax return to receive it.
Does the calculator account for fees?
Yes. The calculator allows you to set an annual fee percentage, which is deducted from your investment return to show the net growth of your pot.
Can I see monthly breakdowns?
Yes. The calculator shows a monthly breakdown of your contribution, tax relief, and net cost. This helps you understand the monthly impact of your SIPP contributions.
