FAQ

Frequently asked questions

Helpful answers to common questions about this calculator.

How much should I save each month in the UK?

A common guideline is to save at least 20% of your take-home pay. However, any amount saved regularly is beneficial. Start with what you can afford and increase contributions over time.

What is the best way to save money in the UK?

ISAs (Individual Savings Accounts) are the most tax-efficient way to save in the UK, with a £20,000 annual allowance. Cash ISAs suit short-term goals, while Stocks and Shares ISAs are better for long-term growth.

How does compound interest boost my savings?

Compound interest means you earn interest on both your deposits and previously earned interest. Over many years, this snowball effect can significantly increase your total savings beyond your contributions alone.

What interest rate should I expect on UK savings accounts?

UK savings rates vary with the Bank of England base rate. Compare accounts using the AER (Annual Equivalent Rate) and consider fixed-rate bonds for higher rates if you can lock away your money.

Should I save or pay off debt first?

Generally, prioritise paying off high-interest debt (credit cards, overdrafts) before building savings, as debt interest usually exceeds savings interest. Keep a small emergency fund while paying down debt.
