A budget in Budget OK is a monthly limit on one category. Once it is set, the category shows what is already spent and what is left, so you learn about an overspend before it happens rather than at the end of the month.
Step by step
1. Open the category. Tap it on the dashboard, in the Expenses block.
2. Press “change” under Budget. The field sits at the top left of the category screen, next to the amount spent.
3. Enter the limit for the month and save. For example 900 for groceries. The number under the category icon on the dashboard now shows the limit.
4. Watch it as you spend. Under the category you see the spent amount against the limit. When the limit is passed, the figure is highlighted so you notice it without opening a report.
Where to get the numbers
Setting limits from scratch usually fails: the numbers are guesses and the budget breaks in the first week. Track without limits for one month first, look at what each category actually costs, and set limits from those figures. That order is what makes them hold.
