Income Input Questions
The most fundamental budget question is which income number to use. The answer affects every percentage and balance shown by the calculator.
Income input FAQ for budget calculators
| Question | Answer |
|---|---|
| Gross or net income? | Always net (take-home) — budget what you actually receive |
| Bi-weekly vs monthly? | Multiply bi-weekly paycheck by 26, divide by 12 for monthly equivalent |
| Include 401(k) in income? | If payroll-deducted, 401(k) is already excluded from take-home — do not add back |
| Variable month income? | Use 12-month average for the most accurate monthly baseline |
| Include spouse income? | Yes for household budget — enter combined take-home for all income sources |
| Side income frequency? | Average monthly — include if it recurs at least 6 months of the year |

If your calculator results show you saving 30% of income but you have $0 in your savings account after 12 months, the inputs are wrong. A budget calculator is only as accurate as the numbers entered. Go back and audit your last 3 months of actual statements before trusting any result.
