Open Pension Contribution CalculatorPensions are tax-efficient saving
Pension contributions are often one of the most tax-efficient ways to save because tax relief and employer contributions can boost the amount going into your pot. Use the AtlasPeak Pension Contribution Calculator to compare employee cost, employer matching and projected retirement pot.
The two common tax relief methods are relief at source and net pay. Relief at source adds basic-rate tax relief to your contribution. Net pay takes contributions before tax through payroll.
Employer matching
Employer matching is valuable because it is extra money into your pension. If an employer matches contributions up to a limit, contributing less than that limit can mean leaving part of your pay package unused.
Auto-enrolment sets minimum contributions, but many people choose to pay more. The right amount depends on age, retirement target, debts, cash savings and affordability.
Allowances and access
The annual allowance is GBP60,000 for many people, though tapering and other rules can apply. The lifetime allowance has been abolished, but pensions still have tax rules around withdrawals and lump sums.
You normally cannot access pension money until the minimum pension age. That makes pensions powerful for retirement but unsuitable for emergency savings or short-term goals.
Defined contribution versus defined benefit
Most workplace pension pots are defined contribution: contributions are invested and the final pot depends on contributions, investment returns and charges. Defined benefit schemes promise an income based on salary and service, so a simple pot projection does not capture them.
Use the pension calculator for defined contribution planning, then check your scheme documents for exact contribution, tax relief and matching rules.

It depends on age, income, employer matching, retirement target and affordability.
What is employer pension matching?
Employer matching means your employer contributes more when you contribute, up to a scheme limit.

Yes. Many people build several pots from different jobs, and may later consolidate them.
When can I access my pension?
Access depends on pension rules and minimum pension age, so pensions are for long-term retirement saving.
