Tennessee Income Shares Model

Tenn. Comp. R. & Regs. 1240-02-04 · Tenn. Code Ann. § 36-5-101

Calculator

Enter both parents' monthly gross incomes, the number of children, and the parenting schedule. The calculator applies the BCSO schedule, the above-cap formula where it engages, the statutory presumptive cap analysis under § 36-5-101(e)(1)(B), and any add-ons or deviations you specify. Every computed line shows the rule that authorizes it. The worksheet downloads in two formats: AOC-format for chancery filing and an annotated version for mediation and analysis. Free, no signup.

Parents

Parent A label

Parent B label

Pick which parent is the Mother — required for the AOC form. Selecting one parent's role auto-sets the other.

Parenting plan

Tennessee labels the parent the children live with most as the PRP (Primary Residential Parent). The other parent is the ARP (Alternate Residential Parent). Support generally flows from ARP to PRP.

Who is the ARP (paying parent)?

Children

Days pre-fill from the plan; override per child only if their schedule actually differs.

Number:

Per-child schedules that differ from the overall plan are recorded on the AOC form but do not change the math — the calculator still uses the parent-level totals above. Consult counsel for genuinely split per-child schedules.
