Free Baby Clothing Budget calculator with clear step-by-step results.
Babies outgrow a full wardrobe several times in the first two years, so cost is driven by size changes rather than by seasons. This multiplies size changes by garments per size, then blends new and secondhand prices to give the annual spend and the monthly amount to set aside.
Garments needed
Garments = size changes x garments per size
Blended cost
Cost = new items x price + secondhand items x price x secondhand ratio
Around 8-12 covers a size if you do laundry twice a week: roughly 6 bodysuits, 4 sleepsuits and a few outer layers. Fewer laundry cycles means more garments.
Gifts and hand-me-downs are free, but bundle purchases from resale apps typically run 25-40% of retail. Set the ratio to 0 if everything comes free.
