How this calculator works

Analyze savings ratio, investment ratio, debt ratio, expense ratio, and an overall monthly financial health score.

Financial ratios compare each monthly category against income. Overall score combines savings, investment, debt, and expense pressure.

Example calculation

If income is $6,000, savings are $1,200, investments are $800, and debt payments are $500, the savings ratio is 20%, investment ratio is 13.3%, and debt ratio is 8.3%.

Tips to improve the result

  • Use ratios to compare months even when income changes.
  • Keep debt pressure low before increasing lifestyle spending.
  • Track savings and investments separately.
  • Use 50/30/20 as a reference, not a rigid rule.

The rating is a practical planning signal, not financial advice. Adjust the assumptions to compare different monthly scenarios.

FAQ

Is this calculator financial advice?

No. It is an educational planning estimate based on your inputs.

How often should I update the numbers?

Update the numbers monthly or whenever income, debt, expenses, or investment assumptions change.

Why does the rating matter?

The rating gives a quick interpretation so the result is easier to act on.

Can I use this for business finances?

You can use it for simple estimates, but business accounting may require more detailed tools.

Are taxes included?

Only when a tax input is available. Otherwise the calculator uses the values you enter as-is.
