Workplace Pension Contribution Calculator
Total monthly pension contribution.
Calculate combined monthly pension contribution from employee, employer match, and tax relief at your salary and contribution rate.
What this tool does
This calculator shows the total monthly amount flowing into a workplace pension by combining three components: the employee's contribution from salary, the employer's matching contribution, and the tax relief applied to the employee portion. Enter your annual salary, the percentage you contribute, your employer's match rate, and your applicable tax relief rate to see the combined monthly total. The result represents the actual pension funding each month across all three sources. The employer match and tax relief typically have the largest impact on the final figure. For example, someone earning 50,000 annually contributing 5% with a 100% employer match and 20% tax relief would see how these elements combine monthly. The calculator assumes contributions are consistent year-round and doesn't account for salary changes, benefit suspensions, or variations in tax relief eligibility. The output is for illustration only.

50,000 salary, 5% employee contribution (208/month), 3% employer match (125/month), 20% tax relief on employee portion (42/month) = 375 total monthly. Employer match is an additional contribution; contributing below the matched level forgoes a portion of the employer contribution.
A worked example
Try the defaults: annual salary of 50,000, employee contribution of 5%, employer match of 3%, tax relief of 20%. The tool returns 375.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Annual Salary, Employee Contribution %, Employer Match %, and Tax Relief %. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
The formula behind this
Monthly = annual / 12. Employee amount grossed up by tax relief. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
How to use this beyond the first run
Re-run the calculation once a year. Life changes — pay rises, new expenses, interest-rate shifts — and the figure that looked right 12 months ago often isn't today. Annual recalibration keeps the plan honest.
What this doesn't capture
The calculation assumes a steady savings rate and a stable interest rate. Real saving journeys include emergencies, windfalls, and rate changes — especially in easy-access products. The figure is a direction of travel, not a guarantee.
What to calculate alongside this
One figure by itself is fragile. The pension calculator, the catch up savings calculator, and the college savings calculator cover adjacent ground — the answer to any one of them changes how you read the output from this tool.
Combined monthly pension contributions from employee, employer match, and tax relief equal 375.00.
Inputs

Sources & Methodology
Methodology
This calculator computes total monthly pension contributions by summing three components. It divides the annual salary by 12 to establish the monthly baseline. The employee contribution is calculated as a percentage of monthly salary. The employer contribution is calculated as a matching percentage of the same monthly salary. Tax relief is applied as a percentage uplift to the employee contribution, reflecting the tax-advantaged nature of pension savings. The three amounts are then added to produce the total monthly contribution figure. The model assumes a constant salary throughout the year, a fixed contribution percentage, and a consistent employer match rate. It does not account for contribution limits, changes in tax circumstances, fees, investment growth, or variations in take-home pay due to other deductions or tax bracket effects.
