Unit Price & Extended Cost Calculator
Compare package prices on a common unit basis or extend a unit price to the required quantity.
Set up your calculation
An illustrative example is loaded. Replace its values with your measurements, costs or documented settings.
Calculation
Your result
- Price per unit
- 5 USD/unit
- Cost for required quantity
- $25.00
- Whole packages to buy
- 1
- Whole-package purchase cost
- $60.00
The quote handoff carries your inputs and assumptions. Only an explicit base cost is suggested as a quote cost; prices, rates and measurements remain planning notes.
How it works
Unit price = package price ÷ package quantity. Extended cost = unit price × required quantity.
- Compare like units: board feet with board feet, pieces with pieces, or length with the same length unit. Fractional quantities are allowed for measured stock.
Compare hardware packs on the same basis
| Input or step | Example value |
|---|---|
| Pack price | $18 |
| Pieces per pack | 24 |
| Cost per piece | $18 ÷ 24 = $0.75 |
| Pieces required | 40 |
| Cost allocated to 40 pieces | $30 |
If only full packs are sold, buying 48 pieces costs $36. The calculator shows the allocated cost and whole-package purchase cost separately.
Common questions
Does the calculator show the cost of whole packs?
Yes. Cost for required quantity shows the allocation to your job. Whole packages to buy and whole-package purchase cost show the rounded-up purchase separately.
Can I compare two different units?
Convert them to the same unit and equivalent specification first. A price per sheet cannot be compared directly with a price per board foot.
Use this in your project
Continue with the next measurement or cost, then keep the assumptions with your quote.
