See what you could earn

Example inputs

Enter your balance and annual percentage yield (APY) from your bank statement. Choose how much extra interest would make switching worthwhile.

Transfer and switching assumptions

Your current account is modeled with no monthly fee. Contributions arrive at month end. During a transfer delay, money is modeled at your current APY. Adjust the cost for fees or lost access.

Your next step

Switching meets your extra-interest target.

What still needs checking

Some account details still need checking, including fees, balance limits and who can open it. Confirm them with the bank before switching. This is an estimate, not a confirmed account offer.

When is switching worth it?

When the extra interest over your time horizon clears your chosen threshold after fees, switching costs and access needs. A higher APY alone does not settle the decision.

What should I check each month?

Record the interest your bank paid, update your goals and check your current rate. Set a reminder for your next review.

What is verified?

Published observations, your assumptions and manual receipts are separate. Complete reviewed account terms and long-enough rate history are not currently available for these comparisons.
