But it's never too late to start closing that gap. Use the calculator below for an estimate of how much you might have missed, to set you on the path to doing something about it.
Your estimate is based on typical scenarios, so your actual figures will depend on investment returns, inflation, salary changes and when you plan to retire.
What is Auto-Enrolment?
Auto-Enrolment is a government scheme introduced in 2012 that requires employers to automatically enrol eligible employees into a workplace pension scheme. Both the employer and employee contribute to the pension, with the employer contribution being essentially free money on top of your salary.
However, not everyone qualifies. If you're self-employed, under 22, a carer, earn below £10,000 per year, or work in certain gig economy roles, you likely won't be auto-enrolled, meaning you miss out on these valuable employer contributions.
What are the 3% employer contributions?
Under Auto-Enrolment, employers must contribute a minimum of 3% of your qualifying earnings into your pension pot. Some employers choose to contribute more than this. This is free money on top of your salary that goes towards your retirement.
If you're not eligible for Auto-Enrolment, you miss out on these ongoing contributions and all the compound growth they would generate over the years.
What assumptions does this calculator make?
Employer contribution: We use 3% as the default, as employers have to pay at least 3% of an employee’s annual ‘qualifying earnings’ into their pension. You can adjust this if your employer contributed more.
Investment growth: We assume 5% annual growth after inflation, based on long-term average pension returns. Actual returns will vary.
Wage growth: For future projections, we assume 2.5% annual pay rises, the UK average. Adjust based on your expectations.
Retirement age: The calculator uses your input for years until retirement to calculate how many years your contributions would be invested in the market. These are estimates. Your actual results will depend on real-world returns, inflation, salary changes, and when you retire.
