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 free money; missing the full match means leaving money on the table.
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. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.
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. Worth a few minutes each, honestly.
Workplace pension produces a monthly contribution total based on the inputs provided.
