The 50/30/20 rule splits your after-tax income three ways: fifty for needs, thirty for wants and twenty for savings and debt repayment. It is popular because it is easy to remember. It is a starting point, not a law, and for many budgets it does not fit.
This guide is about testing it against your own numbers rather than accepting it or dismissing it.

5 things to do
Ticks are for this visit only. Nothing here is saved anywhere.
Adjust it, do not abandon it
If your needs come to sixty percent, the rule is telling you something true: this is a tight month. You can adjust the split to fit, perhaps sixty, twenty and twenty, and still have a useful picture. The value of the rule is in making the three groups visible, not in the specific numbers.
Watch for the bills that are not monthly. A rule applied to twelve regular bills will be off if a quarterly premium and an annual renewal are missing. A monthly bills list fixes that. If your income varies, start from how to budget when your income is different every month.
