Healthcare Opportunity Cost Calculator

150 monthly premium over 20 years at 7% invested grows to roughly 78,100. Whether insurance is worth it depends on the probability of catastrophic healthcare costs and your tolerance for them. The tool does not evaluate whether to insure — it quantifies the alternative so the decision is informed.

How to think about it

Insurance is paying for certainty. If you could comfortably pay a 30,000 catastrophic bill from savings, insurance provides reassurance at a compound-growth cost. If you couldn't, insurance provides real protection. What works depends on your balance sheet and risk tolerance.

Run it with sensible defaults

Using monthly premium of 150, years of 20 years, investment return of 7%, the calculation works out to 78,139.00. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Monthly Premium, Years, and Investment Return — do not pull with equal force.

How the math works

Standard future value of monthly annuity. Does not model insurance payouts, so this is strictly the cost side of the ledger. A complete analysis combines this with expected value of claims (probability × average claim cost).

What the result tells you

The calculation distils your inputs into a single figure. Its value is in seeing how that figure shifts as the inputs change.

What this doesn't capture

The result reflects only the inputs you provide and the assumptions built into the formula. It is a simplified model rather than a complete picture, and factors specific to your situation may matter just as much.

Worked example

A 35-year-old individual pays 180 per month in health insurance premiums and plans to continue until age 65 (30 years). If that same 180 were invested monthly at an average annual return of 6%, the future value would reach approximately 175,000. This illustrates the cumulative weight of recurring premiums over a working lifetime. The calculation shows the magnitude of capital that is, in this scenario, allocated to insurance rather than investment growth.

When this metric matters

• Comparing the cost of staying insured versus building a self-funded health reserve
• Evaluating the trade-off between premium payments and long-term wealth accumulation
• Understanding how monthly insurance costs compound over decades
• Assessing the opportunity cost of healthcare spending in retirement planning
• Modelling financial scenarios where insurance coverage changes or lapses

What this calculation shows and does not show

The calculator models the future value of premiums paid over time, assuming consistent monthly contributions and a steady investment return. It shows the financial magnitude of insurance as an expense stream.

What it does not capture: actual insurance payouts, the probability or cost of medical claims, tax treatment of investment gains, inflation effects on both premiums and healthcare costs, or the real-world volatility of investment returns. It also does not account for changes in premium amounts, coverage gaps, or periods without insurance.
