Money Saving Expert Isa Calculator

An Individual Savings Account (ISA) is a tax-efficient savings vehicle in the UK that allows you to save or invest money outside your taxable income. This calculator helps you estimate your potential ISA savings and compare different ISA types.

What is an ISA?

An ISA is a tax wrapper that allows you to save or invest money tax-free in the UK. There are two main types of ISAs:

Cash ISAs - For saving money in a bank or building society account
Stocks and Shares ISAs - For investing in stocks, shares, and other investment products

In addition to the main ISA types, there are also:

Junior ISAs - For parents to save for their children's education and future
Lifetime ISAs - For people aged 18-39 to save for retirement

Each year, you can contribute up to the annual ISA allowance, which is currently £20,000 (2023/24).

Types of ISA

There are several types of ISAs available in the UK:

Cash ISA

A Cash ISA allows you to save money in a bank or building society account while enjoying tax-free growth. The interest earned is free from income tax and capital gains tax.

Stocks and Shares ISA

A Stocks and Shares ISA lets you invest in stocks, shares, and other investment products. The dividends and capital gains are tax-free, and the money you put in is protected from inheritance tax.

Junior ISA

A Junior ISA is designed for parents to save for their children's education and future. The money grows tax-free and is protected from inheritance tax.

Lifetime ISA

A Lifetime ISA is available to people aged 18-39. It offers tax-free growth and a government bonus of 25% on contributions up to £4,000 per year. The money can be used for retirement or a first home.

Click the "Calculate" button to see your estimated ISA savings

The calculator will display your estimated total savings after the specified number of years, including the growth of your contributions and the interest earned.

Example Calculation

Let's look at an example to see how the ISA calculator works:

Scenario

ISA Type: Cash ISA
Annual Contribution: £5,000
Annual Interest Rate: 2.5%
Number of Years: 10

Calculation

The formula used for the calculation is:

FV = P * (1 + r)^n where: FV = Future Value P = Annual Contribution r = Annual Interest Rate (as a decimal) n = Number of Years

Plugging in the numbers:

FV = £5,000 * (1 + 0.025)^10 FV = £5,000 * 1.2820 FV = £6,410

After 10 years, you would have approximately £6,410 in your Cash ISA.

Assumptions

The interest rate remains constant throughout the investment period
No additional contributions are made after the initial amount
No withdrawals are made during the investment period
