Projected vs target

Note: A negative gap is commonโ€”it means this lifestyle tier costs more than your current income supports while also saving at your target rate. Options: reduce savings rate, select a lower tier, increase income projection, or accept that some years will draw from savings. Many families operate with temporary gaps during peak child-rearing years.

Methodology

This calculator projects costs from your first child's birth year through the planning horizon, applying category-specific inflation rates. Children are modeled with the specified spacing; costs scale based on how many children are "active" (ages 0-22) in each year. Housing costs remain constant (you pay for space regardless of occupancy). K-12 costs apply ages 5-17. College costs apply ages 18-21.

Pre-tax earnings calculated as: Total Cost / (1 - Effective Tax Rate). Tax credits reduce effective burden but are not modeled granularly in lifetime projection.
