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.
- Purchase-quantity basis. Quantity/usage variance is separate; favorable cost is not necessarily favorable quality.
Example Calculation
- Actual unit price: 6
- Standard unit price: 5
- Actual quantity purchased: 100
Actual unit price = 6; Standard unit price = 5; Actual quantity purchased = 100. The primary result is 100.
Frequently asked questions
How do I use this calculator?
Enter actual unit price, standard unit price, actual quantity purchased. The result updates automatically. Use Reset to restore the example values.
What method does it use?
variance=(actual price−standard price) × actual purchased quantity.. Purchase-quantity basis. Quantity/usage variance is separate; favorable cost is not necessarily favorable quality.
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.
Are my inputs saved online?
