The Budget Calculator applies the 50/30/20 budgeting rule to your income, breaking down spending into Needs, Wants, and Savings. Enter your income and spending categories to see if you are on track with this proven financial planning framework. Use it to identify areas to cut spending and increase savings.

Enter your monthly after-tax income and your spending by category. The calculator allocates your spending into Needs (50%), Wants (30%), and Savings (20%) using the 50/30/20 rule. Review the breakdown to see where you stand and where to adjust.

Examples

50/30/20 Budget on $5,000/Month Income

With a monthly take-home pay of $5,000, the 50/30/20 rule allocates $2,500 for needs (rent, utilities, groceries, insurance), $1,500 for wants (dining out, entertainment, subscriptions), and $1,000 for savings and debt repayment. If your rent alone is $1,800, you would need to trim other needs to stay within the 50% target.

Family Budget on $8,500/Month Income

A family earning $8,500/month after taxes has fixed expenses of $3,200 (mortgage $2,100, car payment $450, insurance $350, utilities $300), variable expenses of $2,800 (groceries $900, childcare $1,200, gas $200, dining $500), and targets $1,500 for savings. This leaves $1,000 as a buffer, giving them a 17.6% savings rate.

Quick Tips

  • •Track your actual spending for 3 months to see real patterns before adjusting your budget targets.

  • •Automate savings by setting up automatic transfers to savings on payday. "Pay yourself first" before spending.
  • •Build an emergency fund of 3-6 months of expenses in a separate account before investing or paying down debt.
  • •Use the 50/30/20 rule as a starting framework, then customize it based on your goals (early retirement may require 70% savings).
