What is the CAPHRA Calculator?
CAPHRA stands for Cost Avoidance & Portfolio Habit Return Analysis. It helps you estimate how much a recurring expense could become if redirected into long-term investing.
Think of it as an opportunity-cost tool. Instead of asking, “Can I afford this today?” CAPHRA asks, “What would this be worth in 10, 20, or 30 years if invested consistently?”
How this calculator works
1) Habit spending baseline
The calculator starts with your daily cost and multiplies it by frequency and 365 days per year. That creates your base annual spending.
2) Rising costs over time
If your habit gets more expensive over time (for example, coffee prices rising), CAPHRA increases each year’s contribution amount using your annual price increase percentage.
3) Monthly compounding
Each year’s avoided spending is contributed monthly and compounded monthly at your expected annual return. This gives a realistic long-term growth estimate.
What your output means
- Total Habit Cost Avoided: How much you would have spent over the full period.
- Projected Investment Value: What those redirected dollars might grow to.
- Investment Growth: Earnings generated by compounding, above your contributions.
- CAPHRA Multiplier: Final value divided by total habit cost.
Example scenario
Suppose you spend $5 per day on one habit, prices rise 3% per year, and you invest at an average 8% annually for 30 years. CAPHRA often shows a meaningful six-figure result, illustrating how small recurring decisions can compound into significant wealth.
Use CAPHRA wisely
This is not about eliminating every pleasure. It is about choosing where your dollars go. A practical approach:
- Keep the habits that truly improve your quality of life.
- Cut or reduce habits with low personal value.
- Automate investing so savings actually get invested.
- Re-run CAPHRA yearly as your spending and goals evolve.
Important notes
- Returns are assumptions, not guarantees.
- Markets are volatile; actual outcomes vary.
- Taxes, fees, and behavior can materially affect results.
