Auto Enrolment Pension Calculator

Reviewed by Calculator Editorial Team

Auto Enrolment is a UK government scheme that requires most employers to automatically enrol their eligible employees into a pension scheme. This calculator helps you estimate your pension contributions and potential retirement savings.

How Auto Enrolment Pension Works

The Auto Enrolment scheme was introduced in 2012 to help workers save for retirement. It requires employers to:

  • Offer eligible employees a workplace pension
  • Make automatic enrolment contributions
  • Provide information about the pension scheme

Key Components

There are three main types of contributions:

  1. Employer contributions - The minimum contribution your employer must make (usually 3% of salary)
  2. Employee contributions - The amount you choose to contribute (minimum 5% of salary)
  3. Salary sacrifice - When you reduce your take-home pay to increase your pension contributions

Note: The minimum contributions are subject to change. Always check the latest government guidelines.

Using the Calculator

Our calculator helps you estimate your pension contributions and potential retirement savings. Simply enter your details in the right panel and click "Calculate".

What You Need to Know

The calculator uses these assumptions:

  • Minimum employer contribution: 3%
  • Minimum employee contribution: 5%
  • Average annual pension growth rate: 7%
  • Retirement age: 65

The results show:

  • Your total annual contributions
  • Estimated pension pot at retirement
  • Breakdown of employer and employee contributions

Formula Explained

The calculator uses these formulas to estimate your pension:

Total Annual Contributions = (Salary × (Employer Contribution % + Employee Contribution %)) / 100

Estimated Pension at Retirement = (Total Annual Contributions × ((1 + Growth Rate)^(Retirement Age - Current Age) - 1)) / Growth Rate

Where:

  • Salary = Your annual salary
  • Employer Contribution % = Your employer's contribution percentage
  • Employee Contribution % = Your chosen contribution percentage
  • Growth Rate = Average annual pension growth rate
  • Retirement Age = Your planned retirement age
  • Current Age = Your current age

Worked Example

Let's say you earn £30,000 per year, are 30 years old, and plan to retire at 65. You choose to contribute 8% of your salary.

Calculation Value
Employer Contribution (3%) £900
Employee Contribution (8%) £2,400
Total Annual Contributions £3,300
Estimated Pension at 65 £125,000

This example assumes a 7% average annual growth rate. Your actual pension pot may vary based on market conditions and investment choices.
