UK Pension Calculator 2026: Workplace, SIPP and State Pension Guide

UK Pension System: Three Pillars of Retirement
The UK retirement system has three layers: state pension (GBP 11,502 per year maximum), workplace pension (auto-enrolment at 8 percent minimum), and personal pension or SIPP (additional voluntary contributions). Most people will need all three to retire comfortably. The Pensions and Lifetime Savings Association estimates you need GBP 43,100 per year for a comfortable retirement as a couple — meaning roughly GBP 31,600 from pensions beyond the state pension. Use our retirement calculator to check if you are on track.
Always Take the Full Employer Match
Your employer contributes at least 3 percent of qualifying earnings to your workplace pension. Many employers match higher contributions — some up to 10 percent. Not taking the full match is turning down free money. If your employer matches up to 6 percent and you only contribute 5 percent, you are leaving 1 percent of your salary on the table every year. Over a 30-year career earning GBP 40,000, that 1 percent unmatched equals roughly GBP 28,000 in lost retirement savings. Check with your HR department for the full matching schedule.
Salary Sacrifice: The Tax-Efficient Secret
Salary sacrifice is the most tax-efficient way to fund your pension. Instead of receiving salary and paying tax then contributing to your pension, you reduce your salary before tax. A GBP 500 per month pension contribution through salary sacrifice costs a 40 percent taxpayer only GBP 280 in lost take-home pay (versus GBP 300 through normal contributions). Over 20 years at 7 percent growth, that extra GBP 20 per month grows to over GBP 10,000. Model your pension growth with our compound interest calculator and investment calculator.

Frequently Asked Questions
How much state pension will I get in 2026?
The full new state pension is GBP 221.20 per week (GBP 11,502 per year) for 2025-26. You need 35 qualifying years of National Insurance to get the full amount. 10 years minimum for any state pension. Check your NI record at gov.uk.
How much should I save for retirement in the UK?
A common rule: halve the age you start saving and contribute that percentage of salary. Start at 30: save 15 percent. Start at 40: save 20 percent. The auto-enrolment minimum of 8 percent (5 percent employee plus 3 percent employer) is unlikely to provide a comfortable retirement alone.
What is salary sacrifice for pensions?
You give up part of your salary and your employer puts it into your pension instead. You save income tax AND National Insurance on the sacrificed amount. On GBP 500 per month salary sacrifice at 40 percent tax, you save GBP 200 in tax plus GBP 10 in NI versus paying from net pay.
When can I access my pension?
Currently age 55, rising to 57 from 6 April 2028. State pension age is 66, rising to 67 by 2028 and 68 by 2046. You can take 25 percent of your private pension as a tax-free lump sum, with the rest taxed as income.
SIPP vs workplace pension: which is better?
Take your employer match in the workplace pension first (free money). Then consider a SIPP for additional contributions if your workplace scheme has limited fund choices or high fees. You can transfer old workplace pensions into a SIPP to consolidate and get better investment options.
