Multi-Child Cost Calculator
Total cost of raising up to five children, with the sibling discount that single-child calculators miss.
The first child costs about $310,000 to 18 and each additional child roughly $263,500 — so three children total about $837,000, or $3,875 a month across eighteen years.
