Sample Calculations for Residential CreditUsing The Betson Method and the Spring Method Child Support Schedule Workgroup July 24, 2008
Factual Assumptions • Child is 10 • Assume Dad = NCP because his income is higher • Mom net income $2000 • Dad net income $3000 • Dad = 60% of income • Mom = 40% of income • BCSO = 443 Dad, 295 Mom = 738 total
The Betson Formula • Residential credit = R x T x BCSO + (1 – S) x D x BCSO • R = % of overnights with NCP • T = proportion of the BCSO that is transferred between households when child changes residence (assume 40%) • S = NCP % of net income • D = duplicated expenses (assume 50%)
Betson Formula for Residential Credit (R x .4 x BCSO) + [(1 – S) x .5 x BCSO]
Betson Formula for NCP obligation [S x BCSO] – {[R x .4 x BCSO] + [(1 – S) x .5 x BCSO]}
NCP Obligation when BCSO = 738 and NCP % of income = 60%(Betson) .60 x 738 – {[R x .4 x 738] + [(1 – .60) x .5 x 738]} = 442.8 – [295.2R + (.4 x .5 x 738)] OR 442.8 – [(R x 295.2) + 147.6]
Child 100% with Mom(Betson) NCP obligation $443 (no residential credit)
Child 90% with Mom(Betson) NCP obligation = [.60 x 738] – {[.1 x .4 x 738] + [(1 – .60) x .5 x 738]}= 442.8 – (29.52 + 147.6) = 442.8 – 177.12 = $265.8
Child 80% with Mom(Betson) NCP obligation = .60 x 738 – {[.2 x .4 x 738] + [(1 – .60) x .5 x 738]}= 442.8 – (59.04 + 147.6) = $236.16
Child 70% with Mom(Betson) NCP obligation = .60 x 738 – {[.3 x .4 x 738] + [(1 – .60) x .5 x 738]} = 442.8 – ( 88.56 + 147.6) = 442.8 – 236.16 = $206.64
Child 60% with Mom(Betson) NCP obligation = .60 x 738 – {[.4 x .4 x 738] + [(1 – .60) x .5 x 738]} = 442.8 – (118.08 + 147.6) = 442.8 – 265.68 = $177.12
Child 50% with Mom(Betson) NCP obligation = .60 x 738 – {[.5 x .4 x 738] + [(1 – .60) x .5 x 738]} = 442.8 – (147.6 + 147.6) = 442.8 – 295.2 = $147.60
The Spring Method • Traditional “Cross Credit” Method • Direct costs = BCSO x % of overnights • % of overnights = R • S = % of income • Transfer payment = (S x BCSO) – (BCSO x R)
Spring Formula for NCP obligation Transfer payment = (S x BCSO) – (BCSO x R) = (.6 x 738) – 738R = 442.8 – 738R
Child 100% with Mom(Spring) (.6 x 738) – 738R = 442.8 – 0 = $443 (No residential credit)
Child 90% with Mom(Spring) (.6 x 738) – 738R = 442.8 – 73.8 = $369.00
Child 80% with Mom(Spring) (.6 x 738) – 738R = 442.8 – 147.6 = $295.20
Child 70% with Mom(Spring) (.6 x 738) – 738R = 442.8 – 221.4 = $221.40
Child 60% with Mom(Spring) (.6 x 738) – 738R = 442.8 – 295.2 = $147.60
Child 50% with Mom(Spring) (.6 x 738) – 738R = 442.8 – 369 = $73.80
What if Mom makes more than Dad does? Scenario 1 (Betson) Assume R = 10% Transfer Payment = .4 x 738 – ( .1 x .4 x 738 + (.6 x .5 x 738) = 295.2 – (29.5 + 221.4) = $44.30
What if Mom makes more than Dad does? Scenario 2 (Betson) Assume R = 20% S x BCSO = .4 x 738 = 295.2 R x T x BCSO = .2 x .4 x 738 = 59.04 (1-S) x D x BCSO = .6 x .5 x 738 = 221.4 295.2 – (59.04 + 221.4) = $14.76
What if Mom makes more than Dad does? Scenario 3 (Betson) Assume R = 30% S x BCSO – { R x T x BCSO + (1-S) x D x BCSO} .4 x 738 = 295.2 .3 x .4 x 738 = 88.56 .6 x .5 x 738 = 221.4 295.2 – (88.56 + 221.4) = -14.76 Should there be a negative residential credit?
What if Mom makes more than Dad does? Scenario 1 (Spring) Assume R = 10% (S x BCSO) – (BCSO x R) = (.6 x 738) – 738R = 442.8 – 738R = 442.8 – 73.80 = $369.00 Scenario 2 (Spring) Assume R = 20% (S x BCSO) – (BCSO x R) = (.6 x 738) – 738R = 442.8 – 738R = 442.8 – 147.60 = $295.20
What if Mom makes more than Dad does? Scenario 3 (Spring) Assume R = 30% (S x BCSO) – (BCSO x R) = (.6 x 738) – 738R = 442.8 – 738R = 442.8 – 221.4 = $221.40 Scenario 4 (Spring) Assume R = 40% (S x BCSO) – (BCSO x R) = (.6 x 738) – 738R = 442.8 – 738R = 442.8 – 295.20 = $147.60
What if Mom makes more than Dad does? Scenario 5 (Spring) Assume R = 50% (S x BCSO) – (BCSO x R) = (.6 x 738) – 738R = 442.8 – 738R = 442.8 – 369.0 = $73.80 This formula works the same no matter which parent has the higher monthly net income.
