What does AER mean?

AER stands for ‘Annual Equivalent Rate’ and is the interest rate for a whole year, assuming that interest payments within the year (monthly in the case of a Tide Instant Saver) remain in the account and contribute to future interest payments. Simply put, AER is the interest rate including compounding. AER makes it easier to compare different savings accounts on the market and understand which one might be the best fit for your business.

The exchange rate will also update automatically every 30 seconds, allowing you to see how much the person you're paying will receive and how much it'll cost you in real time.

After you’ve made the payment, you can see the exchange rate used again by tapping on the transaction in your timeline. For any rejected outbound payments we will apply the exchange rate available at the time of the return. This means when the payment is returned to you, it might be a different amount.

If you’ve received a payment, you can see these same details by tapping the transaction in your timeline.
