N12-8: Side Project Economics
The financial case for building, the financial case against, and the framework for deciding.
🎯 What You'll Learn
- ✓ Evaluate project ROI realistically
- ✓ Assess opportunity costs
- ✓ Structure projects for learning ROI
- ✓ Build portfolio-worthy work
Lesson 1: Revenue Reality Check
The median side project generates $0 in revenue. The median successful side project generates <$500/month. The purpose of most side projects is not revenue — it's learning, portfolio building, and brand creation. If you're building a side project for revenue, you need product-market fit, distribution, and persistence. Most engineers have none of these.
95% of side projects: $0/month. 4%: $1-1000/month. 1%: >$1000/month.
Even a $0-revenue side project can teach skills worth $20K+ in career capital.
A shipped, deployed project is worth 10x an in-progress project on your resume.
Audit your current or planned side project: is the primary goal revenue, learning, or portfolio? Be honest about which.
Lesson 2: Opportunity Cost Assessment
Every hour on a side project is an hour not spent on: (1) Your primary job (which actually pays), (2) Learning skills directly applicable to career advancement, (3) Network building, (4) Rest and sustainability. If your side project doesn't compound on your primary career trajectory, it's a hobby — not an investment.
Track actual hours per week spent on the side project.
What career-advancing activity could you do with those hours instead?
Does this project make you better at your primary career or is it tangential?
Calculate the opportunity cost of your side project in hours per month. Identify the highest-ROI alternative for those hours.
Lesson 3: The Portfolio Project Framework
If the goal is career capital (not revenue), optimize for demonstrable competence: (1) Use technologies relevant to your target roles, (2) Solve a real problem (not a toy), (3) Write about the architecture decisions, (4) Deploy it publicly, (5) Include metrics. This project should be your "evidence exhibit" in interviews.
Build with the stack used at your target companies.
Solve a problem someone other than you would care about.
Deployed on a real URL, accessible to anyone.
Design a portfolio project that demonstrates competence for your target role. Define the technology, problem, and deployment plan.
