How Florida child support is calculated

Florida Statute 61.30. Income Shares model with guideline tables based on combined net monthly income and number of children. Non-custodial parent pays their pro-rata share to custodial parent, with timesharing credit if the non-custodial parent has 20%+ overnights.

  1. Each parent's net monthly income is calculated (gross minus allowable deductions like taxes and other court-ordered support).
  2. Both parents' net incomes are added together to get the combined income.
  3. The Basic Support Obligation is looked up from the statutory guideline table based on combined income and number of children.
  4. Add-ons (childcare costs and children's health insurance) are added to the basic obligation.
  5. Each parent's share is based on their percentage of combined net income.
  6. If the non-custodial parent has 73+ overnights per year (20%), a timesharing credit reduces their obligation.

What can change your child support amount

Income changes

A substantial change in either parent's income — voluntary or involuntary — can trigger a modification.

Childcare & insurance

Changes in childcare costs or the children's health insurance premiums directly adjust the support amount.

Timesharing shifts

If overnights change significantly, especially crossing the 73-night threshold, support can be recalculated.

Child's special needs

Medical conditions, disabilities, or educational needs can justify a departure from the guideline amount.

Common questions

What people ask about child support

How long does a divorce take in Florida?

Uncontested divorces in Florida can be finalized in as little as 4–6 weeks after the 20-day mandatory waiting period. Contested divorces typically take 6–18 months depending on complexity and county backlog.

Do I need a lawyer to get divorced in Florida?

No. Florida allows pro se (self-represented) divorce filings, especially for simplified dissolution of marriage where both parties agree. However, if children, significant assets, or disputes are involved, most attorneys strongly recommend legal representation.

Is Florida a no-fault divorce state?

Yes. Florida only requires one spouse to testify that the marriage is 'irretrievably broken.' Fault is not required and typically does not affect property division or alimony.

How is property divided in Florida divorce?

Florida uses equitable distribution, which means marital assets and debts are divided fairly — not always 50/50. Judges consider factors like contribution to the marriage, economic circumstances, and duration of the marriage.

Did Florida eliminate permanent alimony?

Yes. Effective July 1, 2023, Chapter 2023-300 eliminated permanent alimony in Florida. The remaining alimony types are bridge-the-gap, rehabilitative, and durational. Durational alimony is capped at 50% of the marriage length for marriages under 20 years.
