Lifetime value of employer pension matching contributions — often the highest-return 'benefit' in a job.

A 60,000 salary with 5% employer match is 3,000 a year 'free'. Over 35 years at 6% compound return, that contribution stream alone builds to roughly 334,300 — before counting the employee's own contribution. Not taking the match is declining six-figure money over a career.

How to use it

Enter salary, employer match rate, years to retirement, and expected pension return rate. The tool computes the compound value of the employer's contribution alone.

What the result means

Primary is the lifetime compound value of employer contributions. Secondary shows annual match, total employer contributions, and the compound growth on top.

The employer match is illustrative returns

It's the highest-return 'investment' most employees can make — typically 50-100% immediate return on the contribution (matched 1:1 or 1:2). Compare to any other investment: they all look worse. Not taking full employer match is one of the most common long-term financial mistakes.

Quick example

With annual salary of 60,000 and employer match of 5% (plus years to retirement of 35 years and pension return of 6%), the result is 334,304.34. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Annual Salary, Employer Match %, Years to Retirement, and Pension Return. 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.

What's happening under the hood

Future value of an ordinary annuity with annual employer contributions compounded at the stated return. Ignores salary growth — real employers usually match a percentage of rising salary, so true value is higher. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Using this in pay negotiations

Knowing the exact figure behind a headline rate gives you specific numbers to anchor to in conversations about pay. "The difference is £X per month after tax" lands harder than "a couple of grand a year". Concrete numbers move decisions.

What this doesn't capture

Tax bands, pension contributions, student-loan deductions, and benefits-in-kind sit outside this calculation. The figure is the headline; your actual position depends on local tax rules and personal circumstances. Pair with a dedicated take-home calculator for the full picture.
