Why use a savings calculator?

Our savings calculator is designed to help you work out how long it will take to reach your savings goal.

You can plan and manage long or short-term savings goals, whether you’re saving for a holiday, a house deposit, planning a wedding or for emergency funds. Our calculator can help you set a clear path for where you want to go.

What will our savings calculator help you calculate?

Our calculator can help you work out how long it will take to reach your savings goal, and determine how much you need to save each month to meet a specific deadline. Additionally, it can show you how your savings can grow over time.

How does compound interest impact my savings, and how can our calculator help?

Compound interest is when you earn interest on both your initial deposit and on the interest already added to your account.

Our calculator takes compound interest into account and so the results you’re given will help you determine exactly how much your savings could be.

How can we help you achieve your savings goal?

We offer a variety of savings accounts with different interest rates and terms. You can choose an account that matches with your specific savings goal and savings deadline.

Our easy access accounts offer you the freedom and flexibility to access your money without needing to wait for a notice period. Perfect for a short-term savings goal. You can compare all our easy access products.

A notice savings account typically offers a better return on your savings, compared to easy access accounts. Our notice savings accounts usually require a notice period of either 35 or 90 days, but this may differ subject to account availability. This type of account is likely to be the best fit for you if you don’t need access to your money in the short-term. You can compare our notice savings accounts.

If you want to save for your child’s or grandchild’s future, we offer a range of children’s savings accounts.
