Compare true educational costs including parent opportunity cost and all expenses
How to use: Introduction: How this education cost calculator works
This calculator estimates and compares the annual and total cost of three schooling options—homeschooling, public school, and private school—using the numbers you enter.
It is designed to capture both explicit out-of-pocket expenses (tuition, supplies, fees, meals, transportation, activities) and the often-overlooked implicit cost of a parent’s time.
What “parent opportunity cost” means
Opportunity cost is the income a parent could earn if they were working instead of spending that time on schooling-related responsibilities.
For homeschooling, this can be substantial because planning, instruction, and supervision can reduce available work hours.
For public and private school, the calculator applies a smaller default time impact to reflect schedule constraints, volunteering, pickups, sick days, and coordination.
Formulas used (annual)
The calculator uses the following model. All values are annual unless noted.
Assumptions and what to customize
- Public school “tax cost” is entered as your estimated annual share of school-related property taxes (or other local taxes). This varies widely by location and home value.
- Public school opportunity cost is fixed at 15% of parent income in the current model.
- Private school opportunity cost is fixed at 5% of parent income in the current model.
- Homeschool transportation is set to $0 in the current model (to preserve existing behavior). If you want to account for driving to co-ops, museums, or sports, include it under “Other Homeschooling Expenses.”
- Grade level is collected and included in the copied summary, but it does not change calculations in the current version.
Worked example (quick)
Suppose a parent could earn $55,000/year and expects to devote 75% of their time to homeschooling.
Opportunity cost is $55,000 × 0.75 = $41,250/year.
If direct homeschool expenses (curriculum, supplies, testing, co-ops, etc.) total $2,200/year, then the homeschool annual total is about $43,450/year.
Over 8 years, that’s roughly $347,600.
Interpreting results (cost vs value)
The lowest-cost option is not automatically the best fit. Consider student needs, special education services, schedule flexibility, social opportunities, school quality in your district, and the long-term career impact of time away from work.
Use this tool as a financial baseline, then weigh non-financial factors alongside the numbers.
Detailed cost comparison ranges (context)
The ranges below are typical ballparks to help you sanity-check your inputs. Your actual costs can be lower or higher depending on location, school type, and how many children share materials.

Limitations
- This tool is a simplified model and does not estimate long-term effects like retirement contributions, career progression, or re-entry costs after a career break.
- Tax credits, vouchers, ESA programs, and 529 plan benefits are not included.
- Costs for multiple children are not automatically scaled; you can approximate by adjusting annual inputs.
