How to use it
- It uses the US school system and benefits. Pick a style: frugal, typical or lavish. Every stage is filled in at once.
- Pick how long you raise the child: to 18 (high school), 22 (college) or a master’s degree.
- Adjust each stage: child care and preschool, public or private schools with lessons and tutoring, and college type, living away and studying abroad where it applies.
- After 18 you can tick living away from home and set the share of tuition you pay. You can also choose whether to subtract government benefits and whether to count local customs such as birthday parties.
The top number is the total, followed by the average per year and per month and the totals for all three end points (18, 22, master’s) so you can see what four more years of college or two more of graduate school add. Below that is where the money goes and a subtotal for each stage.
How it is calculated
Each year costs everyday living (or the away-from-home cost) + the tuition or child care of that stage + lessons and tutoring + one-off costs (birth, customs) − government benefits, summed from birth to the age you picked, in today’s money.
- Everyday living: food, clothing, housing, transport and health care, without tuition, child care or lessons. US figures come from the USDA report (2015 data, CPI-adjusted); Japan’s are derived from a 2024 national survey; Taiwan has no official breakdown so the three levels are private estimates.
- Tuition and child care: official stage figures, such as College Board prices in the US and MEXT’s survey in Japan.
- Studying abroad: one yearly figure covers tuition and living, so home living costs are not added.
- Parents’ share: applied to college and master’s tuition only. Defaults are 100% in Taiwan, 51% in Japan (JASSO) and 50% in the US (Sallie Mae).
Example: the US, typical style, to age 22, with paid family child care, public schools with average activities, an in-state public college, living at home and the Child Tax Credit subtracted comes to about $427,000, or roughly $1,600 a month.
Notes
- No inflation, and no special-needs or major medical costs.
- Items marked “est.” have no official average and vary a lot by region and family.
- Japan’s learning-cost survey was corrected in January 2026; the corrected figures are used here.
