Child Support Snapshot: Delaware
Delaware operates under the Melson Formula model, one of 3 U.S. states using this framework. For a parent supporting one child, the base guideline applies roughly 18% of income, scaling to 26% for two children and 32% for three. That places Delaware at rank #17 of 51 states by single-child base percentage. Unlike capped states, there is no statutory income ceiling, the formula applies to the full reported income before deductions. Median household income here runs $70,176/yr.
Delaware ranks #32 of 51 reporting states on OCSE collection efficiency and #40 by caseload volume, see the case counts, collection rate, and paternity-establishment figures in the enforcement breakdown below.
Delaware allows a parenting time adjustment, which can materially reduce the base obligation when the non-custodial parent exercises substantial overnight time. A percentage figure alone doesn't determine the dollar amount, see how Delaware compares to other guideline models →
How Delaware Calculates Child Support
Delaware uses the Melson Formula, a three-step calculation that first ensures each parent's self-support reserve, then determines primary child support needs, and finally adds a standard of living adjustment (SOLA). Its one-child base rate is in line with the national middle range.
Melson Formula (Delaware Model). Three steps: self-support reserve, primary child support, standard of living adjustment (SOLA).
