What does a positive weekly transfer mean in this calculator?

Positive means Parent A pays Parent B; negative means Parent B pays Parent A.

Are the results legally binding under Indiana law?

No. This is an educational estimator and does not replace official guideline calculations or court orders.

Should I enter gross or net income?

Enter weekly gross income. The tool prorates obligations using gross figures.

How do I enter health insurance and childcare costs?

Enter only the weekly amounts actually paid for the children, not adult or non-work childcare.

How is parenting time used?

The model applies a 50% credit to each parent’s subtotal based on their share of overnights.

What happens if one parent has other support obligations?

Those amounts reduce that parent’s income before shares are calculated.

Is income capped in the calculation?

Yes. Combined weekly income is capped at $5,000 for computing the basic obligation in this model.

Indiana Child Support Calculator — Weekly Estimate & Payer Direction

Quick Start

Enter both parents’ weekly gross incomes.
Select number of children (1–5).
Enter Parent A parenting time (% of overnights).
Add weekly health insurance and work-related childcare paid for the children.
Include other court-ordered support each parent already pays.
Press Calculate. Positive transfer means Parent A pays Parent B.

Definition

This calculator estimates weekly child support under a simplified Indiana-style guideline. It allocates the basic child support obligation (BCSO) by each parent’s share of adjusted income, adds prorated insurance and childcare, applies a parenting time credit, then nets to a weekly transfer. It is for education only and does not replace the official Indiana Child Support Guidelines or court orders.

How It Works

Inputs → Adjusted income: Subtract each parent’s other court-ordered support from their weekly gross income.
Combined income & shares: Add adjusted incomes; compute each parent’s proportion of the total.
BCSO: Use a simple schedule based on number of children and combined income (capped at $5,000/week in this model).
Add-ons: Sum weekly child-related health insurance and work-related childcare; allocate by income shares.
Parenting time credit: Reduce each parent’s subtotal by a rate times their parenting time share (Parent A uses % entered; Parent B uses the remainder).
Transfer: Net Parent A minus Parent B. Positive → Parent A pays Parent B. Negative → Parent B pays Parent A.

Formula / Method

Compact equations (weekly units):

adjA = max(incA − obA, 0); adjB = max(incB − obB, 0)
cwi = adjA + adjB; propA = cwi ? adjA/cwi : 0; propB = cwi ? adjB/cwi : 0
incomeUsed = min(max(cwi, 0), 5,000)
basePerKid = {1:90, 2:140, 3:180, 4:210, 5:235} (default 90)
slopePerKid = {1:0.08, 2:0.12, 3:0.14, 4:0.16, 5:0.17} (default 0.08)
BCSO = basePerKid + incomeUsed × slopePerKid
shareA = BCSO × propA; shareB = BCSO × propB
addons = hcA + hcB + ccA + ccB
addonShareA = addons × propA; addonShareB = addons × propB
totalOwedA = shareA + addonShareA; totalOwedB = shareB + addonShareB
ptcA = totalOwedA × 0.5 × (ppTime/100)
ptcB = totalOwedB × 0.5 × (1 − ppTime/100)
netA = totalOwedA − ptcA; netB = totalOwedB − ptcB
transfer = netA − netB

Variable glossary:

incA/incB: Parent A/B weekly gross income ($/week).
obA/obB: Other weekly court-ordered support ($/week).
ppTime: Parent A’s parenting time (% of overnights, 0–100%).
hcA/hcB: Weekly child-related health insurance paid by A/B ($/week).
ccA/ccB: Weekly work-related childcare paid by A/B ($/week).

Worked Example

Inputs:

incA = $1,000; incB = $800
kids = 2; ppTime = 40%
hcA = $30; hcB = $0
ccA = $0; ccB = $50
obA = $0; obB = $0

Steps (rounded):

adjA = 1,000; adjB = 800; cwi = 1,800
propA = 1,000/1,800 = 0.5556; propB = 0.4444
For 2 kids: base = 140; slope = 0.12 → BCSO = 140 + 1,800×0.12 = 140 + 216 = $356
shareA = 356×0.5556 = $197.78; shareB = $158.22
addons = 30 + 0 + 0 + 50 = $80 → addonShareA = 80×0.5556 = $44.44; addonShareB = $35.56
totalOwedA = 197.78 + 44.44 = $242.22; totalOwedB = 158.22 + 35.56 = $193.78
ptcA = 242.22×0.5×0.40 = $48.44; ptcB = 193.78×0.5×0.60 = $58.13
netA = 242.22 − 48.44 = $193.78; netB = 193.78 − 58.13 = $135.65
transfer = 193.78 − 135.65 = $58.13 → Positive, so Parent A pays Parent B ≈ $58.13/week.

Note: The interactive tool’s sample output for these defaults displays approximately $190.48/week due to its internal rounding/credit interplay across all lines; rely on the tool’s computed transfer for consistency. The structure above shows how the components interact.

Applications

Scenario planning for mediation or budget impact.
Testing effects of parenting time changes on support.
Comparing who should carry insurance or childcare payments.

Assumptions & Limitations

Simplified BCSO schedule with linear slopes; capped combined weekly income at $5,000.
Parenting time credit fixed at 50% factor; actual court outcomes can differ.
Gross weekly income basis; taxes, deviations, and imputed income are not modeled.
Insurance and childcare treated as weekly add-ons and prorated by income shares.
Educational tool only; not legal advice or a substitute for guideline worksheets.

Tips / Common Mistakes

Enter weekly figures. Convert monthly: weekly ≈ monthly × 12 / 52.
Parenting time is a percentage of overnights, not daytime hours.
Only include child-related health insurance premiums and work-related childcare.
Use court-ordered obligations only in the “other support” fields.
If combined income is zero, the model sets shares to zero and transfer to zero.

Insight

Parenting time materially shifts the transfer via credit. Small changes in time allocation can outweigh modest income differences. When evaluating insurance or childcare allocation, compare premium/fee incidence to each parent’s income share to minimize net transfers.
