Pension pot calculator FAQs
Expand the questions below for the key pension projection assumptions, limitations and planning context.
How does the pension pot calculator work?
The Affordit pension pot calculator estimates how a pension pot could grow based on your current savings, monthly contributions, employer contributions, assumed investment growth, fees, inflation and years until retirement. It compounds your current pot, adds future monthly contributions and shows both a projected pot and an inflation-adjusted estimate.
What is a pension pot?
A pension pot is the money built up in a pension account through your contributions, employer payments and potential investment growth. It is usually designed for long-term retirement saving, so access, tax treatment and withdrawal options can depend on pension rules and your personal circumstances.
How much pension will I have at retirement?
It depends on your current pension savings, monthly contributions, employer contributions, retirement age, investment growth, fees and inflation. This calculator helps you test those assumptions quickly so you can compare different pension scenarios.
How much should I pay into my pension each month?
There is no single answer. It depends on your income, essential costs, retirement goals, employer contributions, other savings and desired retirement income. This calculator does not tell you what to do; it lets you compare different monthly contribution levels so the trade-offs are clearer.
Why do employer contributions matter?
Employer contributions can materially increase the final pot over time because they add extra monthly payments that may compound. The calculator separates your own contributions from employer contributions so you can see how each part affects the projection.
Why do fees and inflation matter?
Fees reduce net growth over time, and inflation reduces future spending power. The calculator uses your growth, fee and inflation assumptions to show a headline projected pot and an inflation-adjusted estimate in today's spending-power terms.
Is a pension pot the same as retirement income?
No. A pension pot is the amount built up. Retirement income depends on how you access the pot, investment returns during retirement, tax, charges, pension rules and personal circumstances. The calculator may show a simple illustrative income estimate, but it is not a recommendation.
Does this calculator include the State Pension?
No. This calculator focuses on private or workplace pension savings. It does not estimate State Pension entitlement, tax treatment, annuity rates, pension access rules or product-specific charges.
What growth rate should I use?
The growth rate is an assumption. Investment returns are not guaranteed and can go up or down. You can test different rates to see how sensitive the projection is, then seek regulated advice if you need a personal recommendation.
Is this pension advice?
No. This calculator is for educational guidance only. It does not provide pension, investment, tax or financial advice, and it does not guarantee future returns.
