## Formula

Cost per function point = Total project cost ÷ Function points delivered

- Cost per function point = Total project cost ÷ Function points delivered.
- Inputs used: Currency, Total project cost, Function points delivered.
- Edge handling: Total project cost is required.; Total project cost cannot be negative.; Total project cost must be no more than 1000000000000.; Function points delivered is required.; Function points delivered cannot be negative..

## Inputs

- Currency
- Total project cost
- Function points delivered

## Worked example: $540,000 for 480 function points

The cost is whatever your project actually cost; nothing is assumed about it.
1. Start with Currency: USD, Total project cost: 540000, Function points delivered: 480.
2. Apply the method: Cost per function point = Total project cost ÷ Function points delivered.
3. The cost is whatever your project actually cost; nothing is assumed about it.

## Common questions

### Where does this formula come from?

IFPUG, Function Point Counting Practices Manual — functional size is counted independently of technology, and delivery rate is effort per unit of functional size. See the source link on this page.

### What kind of calculation is this?

Total cost is divided by counted functional size to give a unit cost independent of language and team. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### What are its limits?

A unit cost, not a price. Comparable only across projects costed and counted the same way.

### How do I use the Cost per Function Point Calculator?

Enter the required values for Currency, Total project cost, Function points delivered. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Cost per Function Point Calculator use?

Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### Can the Cost per Function Point Calculator be used for exact decisions?
