Inflation could hold your cash back when prices rise higher than the interest on your savings. The actual amount you've saved will go up, but you might not be able to buy as much with it over time.

The cost of goods over time
This calculator uses historic data to help give a realistic forecast of inflation over the longer term. Simply input an amount for something you might be saving towards and we will show you the impact that inflation could have on the spending power of your savings.
Enter the cost of the item you are saving for over the long term:
| Your savings with interest | Cost of goods after inflation | Impact of inflation on your savings | |
|---|---|---|---|
| After 5 years | £2,148 | £2,394 | -£246 |
| After 10 years | £2,296 | £2,788 | -£492 |
