FAQ
What budgeting rule does this budget calculator use?
It uses the 50/30/20 rule by default, allocating 50 percent to needs, 30 percent to wants, and 20 percent to savings.
Does the Budget Calculator send my data to a server?
No. The Budget Calculator runs entirely in your browser with JavaScript; the values you enter never leave your device and nothing is uploaded or saved.
Should I use net or gross income?
Use take-home (net) income, since the rule is meant to divide the money you actually receive each month.
Is the 50/30/20 split mandatory?
No. It is a guideline. Adjust the proportions to fit your goals, cost of living, and debt situation.
