On the budget page, right below the “Net total available”, add a field called “Daily net available” that dynamically represents the amount of money that can be spent per day. The formula can be simple: “Net total available” / “days left in the budget period”.
For example, if I budget monthly, it’s the 14th of February, and I have a net total of $1050, my daily amount would be 1050 / 15 = $70. If I spend nothing, on the 15th of February it would be 1050 / 14 = $75.
It’s a rather small feature, but a big quality of life improvement.
