50/30/20 budget calculator

The 50/30/20 framework splits monthly take-home pay into three buckets - needs, wants, and savings or debt payoff - as a starting point rather than a strict rule. Enter your income to see the target dollar amounts, and optionally add what you’re actually spending in each bucket to see where the gap is.

After taxes and paycheck deductions - what actually lands in your account.

Housing, utilities, groceries, insurance, minimum debt payments.

Dining out, entertainment, subscriptions, travel.

How the math works

The calculator multiplies monthly take-home income by 50%, 30%, and 20% to produce three target amounts. If actual spending is entered for any bucket, it lines each target up against the real number and shows the difference - over or under - so the comparison is concrete rather than a vague sense of “we spend too much on wants.” Nothing here judges the split; it just does the arithmetic so the conversation can be about the actual dollar gap.

The 50/30/20 budget, explained and what is the 50/30/20 budgeting rule and how to use it cover the framework itself in more depth, including where it tends to break down. If the needs bucket is running high, how to make a budget for the first time walks through building one from scratch, and how to fix a budget that isn’t working covers what to adjust when the targets and reality keep missing each other.
