Budget is balanced but tight. Aim to save at least 10–20% of income for a healthier cushion.

Budget Tips

  • Keep housing under 30%

    Rent or mortgage above 30% of income leaves little room for savings and surprises.

  • Save before you spend

    Treat savings like a fixed bill and transfer it on payday, not after spending.

  • Aim for 50/30/20

    A common starting split: 50% needs, 30% wants, 20% savings and debt repayment.

  • Track every category

    Small categories like subscriptions and food delivery often grow without notice.

  • Watch transportation creep

    Fuel, insurance, and car payments together can quietly take 15–20% of income.

  • Build an emergency buffer

    Aim for 3–6 months of essential expenses before focusing on bigger savings goals.

Formula

Total Expenses = Σ(category amounts) · Remaining Income = Monthly Income − Total Expenses · Savings Rate = (Savings ÷ Monthly Income) × 100 · Expense Percentage = (Total Expenses ÷ Monthly Income) × 100

Worked example

$5,000 monthly income with $1,500 housing, $200 utilities, $500 food, $300 transportation, $200 insurance, $250 debt, $150 entertainment, $400 savings, and $200 other.

  1. Total expenses = 1,500 + 200 + 500 + 300 + 200 + 250 + 150 + 400 + 200 = $3,700
  2. Remaining income = 5,000 − 3,700 = $1,300
  3. Savings rate = (400 ÷ 5,000) × 100 = 8%
  4. Expense percentage = (3,700 ÷ 5,000) × 100 = 74%

Answer: $3,700 expenses · $1,300 remaining · 8% savings rate · 74% expenses · Yellow rating

How it works

A monthly budget is the simplest way to make sure your spending fits inside your income. Listing each category separately turns a vague feeling of "money is tight" into specific numbers you can act on.

Total expenses add up everything you spend in a month. Subtracting that from your income shows what's actually left — money that can go to extra savings, debt payoff, or planned purchases. A negative number means you're spending more than you earn and the budget needs to be trimmed.

The savings rate is the share of your income you set aside each month. Many financial guides suggest 10–20% as a healthy starting point. The expense percentage is the mirror image — the share of income that goes to spending. Lower expense percentages leave more room for savings, investing, and surprise costs.

The Red / Yellow / Green rating combines these numbers into a quick health check. Red means you're overspending. Yellow means the budget balances but leaves little cushion. Green means expenses are well under income and you're saving at a sustainable rate.

Common mistakes

  • Using gross income instead of take-home pay — your real budget is what hits your bank account after tax.
  • Forgetting irregular bills like annual insurance or quarterly taxes — divide them by 12 and include a monthly share.
  • Putting savings last as "whatever is left" — by the end of the month, that's usually zero.
  • Underestimating food and entertainment — track a few real months before assuming what you spend.
  • Ignoring small subscriptions — $10 here and $15 there adds up to a meaningful slice of income.

FAQ

What is a good monthly budget split?
A common starting point is the 50/30/20 rule: 50% of take-home pay for needs (housing, utilities, food, transport, insurance), 30% for wants (entertainment, dining out), and 20% for savings and extra debt payments. Adjust the split to fit your income and goals.
What is a healthy savings rate?
Saving at least 10% of your income is a solid starting point, and 20% or more is considered strong. Even 5% is better than nothing if you're just beginning — the habit matters more than the size at first.
What does the Budget Health Rating mean?
Red means your expenses exceed your income or your budget has no breathing room. Yellow means your budget balances but your savings rate is low. Green means expenses are comfortably under income and you're saving at a healthy rate.
Should I include debt payments as an expense?
Yes. Minimum debt payments are a required monthly bill and belong in the budget. Extra payments above the minimum can be treated as savings toward becoming debt-free.
How often should I update my budget?
Review your budget at least once a month, and rebuild it any time your income or fixed bills change. A quick weekly check-in helps you catch overspending in flexible categories like food and entertainment.
Does this calculator account for taxes?
No — enter your take-home (after-tax) income so the results reflect what you actually have to spend and save.
