Monthly Budget Split (50/30/20)
Used by developers, writers, and creators worldwide.
A monthly budget split calculator divides your take-home pay into three buckets — needs, wants, and savings — using the popular 50/30/20 rule, or any percentages you prefer. Enter your monthly income and the share you want for each category, and it returns the exact dollar amount to assign to essentials like rent and groceries, to discretionary spending, and to savings or debt repayment. If your percentages do not add up to a hundred, it normalises them so the split still matches your full income. Beginners use it to start budgeting without a spreadsheet, and experienced budgeters use it to sanity-check whether their spending is balanced. A clear split turns a vague paycheck into a plan, making it easier to cover the essentials, enjoy some guilt-free spending, and still build a cushion. Use it each payday to keep your money working the way you intend.

FAQ
what is the 50/30/20 rule
It suggests putting 50% of take-home pay toward needs, 30% toward wants, and 20% toward savings or debt repayment. It is a simple starting framework, not a strict law — adjust the percentages to fit your situation and goals.
what if my percentages do not total 100
The calculator normalises them proportionally so the three amounts always add up to your full income. This lets you experiment with custom splits without having to make the numbers sum to exactly a hundred yourself.
