Software Development Cost Estimate
This is a practical guide to building a cost estimate for a software development project — a forecast of the money required to complete the work, adapted to the realities of building and shipping a software product or feature set.
What a Cost Estimate is
A cost estimate is a forecast of the money required to complete the work. For the full concept and how it works in general, see Cost Estimation. On a software development project it plays the same role, tuned to this kind of work.
Why it matters for a Software Development project
Software Development projects live or die on building and shipping a software product or feature set. A well-built cost estimate gives the team a shared, explicit reference for exactly that — reducing ambiguity, aligning stakeholders, and making problems visible early enough to act. Skipping it, or doing it generically, is how software development projects drift into avoidable delay and cost.
What to include
- Labour costs
- Material/equipment costs
- Indirect costs
- Contingency
- Estimate basis and assumptions
Software Development-specific considerations
Tailor the cost estimate to the risks that most often derail software development projects:
- Scope creep
- Technical debt slowing delivery
- Third-party dependency risk
Example
On a real software development project, the cost estimate would be shaped by building and shipping a software product or feature set. In particular, it should explicitly account for the project’s biggest risks — scope creep, technical debt slowing delivery, third-party dependency risk — rather than treating them as afterthoughts.
