Budget & Income

Budget Calculator

Build a monthly budget in minutes. Enter your take-home pay and what you spend by category to see whether you have a surplus to save — or a gap to close.

Income & spending

Enter your take-home pay, then what you spend in each category each month.

Your monthly budget

Left to allocate each month

$500

Great — put this surplus toward savings or extra debt payoff.

Total income

$4,500

Total spending

$4,000

Savings rate

7%

Aim to keep total spending below income and your savings rate as high as you can sustain. A positive "left to allocate" number every month is what builds wealth.

A budget is just income minus a plan

Budgeting sounds tedious, but it comes down to one comparison: does your spending fit inside your income? Enter your numbers above and the calculator shows your surplus or deficit and your savings rate in real time.

Give every dollar a job

A leftover surplus isn't "extra" — it's the money that builds your emergency fund, accelerates debt payoff, and funds investing. Assign it on purpose before it drifts into spending.

Prefer a simpler rule?

If categories feel like too much, the 50/30/20 budget splits your pay into just three buckets. Not sure what your take-home pay is? Estimate it with the paycheck calculator.

Frequently asked questions

How do I make a monthly budget?
Start with your take-home pay, list what you spend by category, and subtract. If spending is below income, you have a surplus to save or use for debt. If it’s above, you have a gap to close by trimming categories. This calculator does the math as you type.
What’s a good savings rate?
Saving 20% of take-home pay is a solid target, and higher is better if you can manage it. Even 5–10% consistently beats none. Your savings rate is the single biggest driver of long-term wealth.
What if I’m spending more than I earn?
Focus on your largest flexible categories first — usually food, transportation, and discretionary spending. Closing even a small monthly deficit prevents debt from growing and frees money to save.
