| Blood Alcohol | Blood Alcohol estimates a health-related number from standard formulas used in fitness and medicine. |
| Budget Allocator | Budget Allocator solves the little math problems of daily life: dates, trips, timers and quick estimates. |
| Business Days | Business Days does calendar arithmetic: counting days, adding intervals, and finding where dates fall in the week or year. |
How to choose
- Age is the best starting point for most people: it covers the core calculation with plain-language steps.
- Use Blood Alcohol when you want the reverse or companion question answered, such as solving for a different variable.
- Pick Budget Allocator for quick estimates and Business Days when you need the detailed breakdown.
- All four run entirely in your browser, show their formulas, and are free with no sign-up.
Common mistakes when comparing
- Comparing results computed with different inputs; keep the inputs identical to compare fairly.
- Mixing gross and net figures across tools.
- Ignoring the assumptions each tool states on its page.
