UK Pension Calculator

Our UK pension calculator projects the size of your pension pot at retirement based on your current age, retirement age, existing pension savings, employee contribution rate, employer contribution rate, and expected investment growth. Pension contributions benefit from tax relief — basic rate taxpayers get 20% relief, meaning a £100 contribution only costs you £80. Higher rate taxpayers can claim an additional 20% through Self Assessment, making pension contributions extremely tax-efficient. The calculator also estimates the annual income your pot could provide in retirement, based on a 4% sustainable withdrawal rate.
