How to read the result
- What it means
- The displayed value is an estimate based on your inputs. It represents the calculated scenario under current assumptions, not a guaranteed amount.
- Calculation limits
- The model uses simplified formulas and cannot account for all variables in your specific case (local regulations, personal conditions, temporal changes).
- Next step
- Use the result as a starting point. Adjust parameters to compare scenarios and validate with a professional when needed.
Glossary+−
- Foregone Wage
The gross amount you would have earned if you had taken a paid position for the same period.
- Annualized Equivalent
A pro-rated 12-month value used to compare payments or costs that occur over shorter periods.
- Quantifiable Benefits
Non-wage items (housing stipend, transport allowance) that can be reasonably converted to a monetary value and added to total opportunity cost.
Key takeaways
Provides a clear, reproducible monetary estimate of opportunity cost for unpaid internships: total for the period and annualized equivalent.

Worked examples
Example — 3-month unpaid internship with no benefits
Compare a $4,500 foregone wage for a 3-month internship.

Example — 6-month unpaid internship with benefits
Foregone wage $6,000 plus $1,200 in housing assistance over 6 months.
Interpretation
Total opportunity cost $7,200; annualized equivalent $14,400.
Frequently asked questions
How is opportunity cost defined here?
Opportunity cost is the direct monetary value of earnings and quantifiable benefits you forgo by accepting an unpaid internship instead of a paid alternative.
Does this calculator include taxes or long-term career effects?
No. Tax treatment and long-term career benefits (skill acquisition, networking) are not included. Enter after-tax amounts if you want post-tax comparisons, and consider qualitative factors separately.
When should I use the annualized equivalent?
Use the annualized equivalent to compare the unpaid internship's foregone earnings with annual salaries or to evaluate across internships of different lengths.
