CLIP Calculator
CLIP = Cost of Lost Investment Potential. Estimate how much frequent small purchases could become if invested instead.

What is a CLIP calculator?
A CLIP calculator helps you measure the long-term impact of small recurring expenses. CLIP stands for Cost of Lost Investment Potential, which is simply the future value of money you spend repeatedly today.
Most people do not struggle because of one giant bad decision. They struggle because little decisions repeat for years without a system. A coffee here, delivery fee there, unused subscription over there. None of these look dangerous in isolation, but compounding can turn “small” into “significant.”
How this calculator works
Inputs you control
- Cost per purchase: The average amount spent each time.
- Times per week: How often the spending occurs.
- Years: Your time horizon.
- Expected return: The annual investment rate used for projection.
- Inflation of purchase cost: How much your repeated spending grows over time.
Core idea behind the math
Each week, the calculator assumes you could invest the amount you did not spend. It then compounds that amount at a weekly rate based on your annual return assumption. If you include inflation, the weekly “saved” amount increases each year, matching how prices tend to rise in real life.
How to use your CLIP result
Your output includes three key numbers: how much you are spending, how much it could become if invested, and the resulting opportunity cost. This is not a guilt tool. It is a prioritization tool.
- Pick one recurring expense that matters least to your quality of life.
- Reduce it by 25% instead of trying to eliminate it overnight.
- Automate transfer of that amount to an investment account weekly.
- Re-run the calculator every 3-6 months and increase your target.
A practical example
Suppose you spend $6 five times a week. That is $30 weekly, or about $130 monthly. On paper, it feels manageable. Over 20 years, at a moderate return rate, the future value can become surprisingly large.
This does not mean never enjoying small purchases. It means buying intentionally: spend fully on what you value, and cut ruthlessly on what you barely notice.
Limitations to keep in mind
- Markets are volatile; returns are never guaranteed.
- Your actual spending pattern may not be perfectly weekly.
- Taxes, fees, and account choice can change outcomes.
- Life quality matters too; not every discretionary expense is “bad.”
Final thought
Financial progress is often less about dramatic sacrifice and more about consistent systems. Use this CLIP calculator to reveal hidden leverage in your budget, then convert that leverage into automated investing. Tiny decisions, repeated over time, build real wealth.
