## How This Pension Calculator Works

This UK pension calculator helps you estimate how your pension could grow over time using a simple, long-term approach.

By adjusting your age, contributions, and expected returns, you can see how consistent investing and compounding may impact your retirement.

It also includes employer contributions and tax relief, which can significantly boost your pension over time.

## Wha**t Your Pension Could Look Like Over Time**

Your pension growth is driven by three main factors:

### Contributions

Regular monthly contributions build the foundation of your pension.

### Employer Contributions

If you’re enrolled in a workplace pension, your employer may contribute — effectively increasing your investment without additional cost to you.

### Investment Growth

Over time, compounding can have a significant impact on your final pension value.

Even small differences in return can lead to large changes over decades.

## Understanding Pension Tax Relief (UK)

Pension contributions in the UK benefit from tax relief.

- Basic rate taxpayers receive 20% tax relief
- Higher rate taxpayers may receive additional relief

This means your contributions are effectively boosted before being invested.

For workplace pensions, this is often applied automatically through your salary.

## How Long Will Your Pension Last?

This **retirement income calculator** also includes a simple retirement drawdown model.

After retirement, you can typically take 25% of your pension tax-free.  
The remaining amount is used to generate income and is taxed as income.

By adjusting your withdrawal amount and expected growth, you can estimate how long your pension may last.

## Important Assumptions

This calculator is designed to give a simple, long-term estimate.

- Investment returns are assumed and will vary
- Inflation is not fully accounted for
- Tax is simplified and may differ based on your situation
- Actual pension performance depends on your investments

Use this as a planning tool, not a prediction.
