Step 1: Choose the Right ISA Calculator
There are different types of ISA calculators available depending on the ISA you’re considering:
- Cash ISA Calculator – Estimates interest earned on tax-free savings.
- Stocks and Shares ISA Calculator – Helps estimate potential investment returns.
- Lifetime ISA (LISA) Calculator – Shows government bonuses and potential growth.
- Innovative Finance ISA Calculator – Calculates returns from peer-to-peer lending.
Choose a calculator that matches your ISA type.
Step 2: Enter Your Initial Deposit
Most ISA calculators will ask you to enter your starting deposit. If you’re opening a new ISA, enter the amount you plan to deposit initially.
Step 3: Input Monthly or Annual Contributions
If you plan to add more money to your ISA regularly, enter your monthly or yearly contributions. Some calculators allow you to see how different contribution amounts affect your savings over time.
Step 4: Adjust Interest Rate or Investment Growth Rate
- For Cash ISAs – Enter the interest rate offered by your bank.
- For Stocks & Shares ISAs – Enter an estimated investment growth rate (often between 4-8% per year, though this varies).
Step 5: Set the Timeframe
Decide how long you plan to save or invest in your ISA. The longer your money stays in an ISA, the more it can grow due to compound interest or investment returns.
Step 6: Review Tax-Free Growth
The calculator will show:
- The total amount saved over time.
- The interest or investment growth earned.
- Any government bonuses (for LISAs).
- Tax-free benefits compared to a regular savings account.
Step 7: Compare Different ISAs
Some calculators allow you to compare different types of ISAs side by side, helping you choose the best option for your financial goals.
Step 8: Make an Informed Decision
After using the ISA calculator, consider:
- Whether to increase your contributions.
- Choosing a different ISA type for better growth.
- Switching providers if you find a better interest rate or lower fees.
