Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Use net credit sales and matching trade receivables. Not an aging schedule.
Example Calculation
- Average trade receivables: 100
- Period net credit sales: 1000
- Days in period: 365
Average trade receivables = 100; Period net credit sales = 1000; Days in period = 365. The primary result is 36.5.

Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
