Every night, we pull in your information about your transactions from your round up accounts that are in use. We’ll round up to the next whole dollar for most amounts, and for transactions that end in an even dollar (ex. $24.00), we’ll round up a whole dollar.
You can always turn off the whole dollar roundup setting within the app. To do so: click on the payment from the Upcoming Payments card of the app, then tap the three-dot menu at the top right of the screen, then select the "Turn off/on dollar round ups" option.
