Accountants Pension Contribution Calculator
Estimate the tax-efficient cost of personal and employer pension contributions, including available annual allowance.
Overview
Use this Accountants Pension Contribution Calculator to estimate the cost of planned personal and employer pension payments. Enter contributions already made, your expected income tax and corporation tax rates, and the annual allowance available to review the estimated tax effects and allowance position.
How it works
The calculator adds planned personal and employer payments to show the new pension contribution, then adds other contributions already made to estimate the total pension input for the tax year. It estimates personal tax relief by multiplying the personal contribution by your entered marginal income tax rate. It estimates the corporation tax effect of an employer contribution using the entered corporation tax rate. The annual allowance result compares total contributions with the allowance you enter; it does not determine whether tapering or carry forward applies.

A £10,000 personal contribution and £5,000 employer contribution add £15,000 to the pension. At 40% personal tax relief and 25% corporation tax, the estimated combined net cost is £10,250, leaving £45,000 of the entered annual allowance.
Frequently asked questions
What does an accountants pension contribution calculator estimate?
It estimates the gross pension contribution, likely personal tax relief, estimated employer corporation tax saving, combined net cost, and the remaining annual allowance based on your entries.
Are personal and employer pension contributions treated differently?
They can be. Personal contributions may receive income tax relief, while employer contributions may be deductible business expenses if the relevant conditions are met. The calculator shows these effects separately.
Does the calculator include salary sacrifice?
No. Salary sacrifice can affect income tax and National Insurance differently, so its results should be assessed separately using the specific arrangement details.
What should I enter as my annual allowance?
Enter the allowance you expect to have available after considering contributions already made, possible tapering, and any carry forward you are entitled to use.
Does the annual allowance include employer contributions?
Generally, pension input includes both personal and employer contributions. This calculator adds both planned amounts and other contributions entered for the tax year.
Why is the personal net cost lower than the gross contribution?
The calculation subtracts estimated income tax relief based on the marginal tax rate you enter. The actual timing and method of relief can vary by pension arrangement.
