I met Richard Hayes at the Sydney OpenCoffee Meetup and he’s written an excellent article that he’s allowed me to reproduce below.
All people working in the Startup / Early Stage consistently asked the same question,
“How do you value business?”
The correct answer is there is no correct answer
Without trying to be facetious here is a number of models that may help.
Anyone wanting further information can attend Richard’s BEERonomics in a pub near you.
Courses in advance corporate finances cost you 2 beers / hour (Cheaper than a MBA)
Example:
A team of 3 developers have written 13K lines of PHP source code to develop a DIY superannuation management software. It has taken 6 months part time (IE 50 hour/wk)
They are all leaving their “real” jobs to pursue their dream.
Sales: Nil
User: 250
Total Cash Spent: $5,800
What is the company worth?
1. Sale Revenue Nil
Future Sales Revenue 2009 $1,000,000 (FV)
Discounted @ 40% pa $510,000
Company valuation $383,000 - $637,000
2. Price Earnings
2009 Sales $1,000,000
2009 Profit $180,000
PE 2 (180K x 2 x 40%) $183,000
PE 5 (180K x 5 x 40%) $459,000
Company valuation $183,000 - $459,000
Replacement value $413,228
The following output is from a real project
Totals grouped by language (dominant language first):
php: 13409 (99.83%)
sh: 23 (0.17%)
Total Physical Source Lines of Code (SLOC) = 13,432
Development Effort Estimate, Person-Years (Person-Months) = 3.06 (36.71)
(Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months) = 0.82 (9.83)
(Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule) = 3.73
Total Estimated Cost to Develop = $ 413,228
(average salary = $56,286/year, overhead = 2.40).
As you can see there is no right answer but valuation is much more about art than science.
