The EveryDollar mobile app will only display budgets from the past two years, but all budgets you've ever created can be viewed from everydollar.com on a computer.
To view a past month, select the drop-down arrow to the right of the month title to reveal a list of months. Use the left arrow on the list of months to locate the one you're looking for.
Please note that if you create a budget and then make a change to a previous month, the change will not be reflected on the subsequent months. If you create October's budget and then make a change to September, the change must be manually made in October.
Pro Tip: If the month has a solid line around it, that means a budget has already been created for that month. A dotted line means a budget has not been created for that month.
Next Step
You may have non-monthly expenses from previous months which are coming due again. If you need to save up for those, it's time to start a Fund.
