Child support in Fairbanks: how it is calculated
Child support in Fairbanks is set by Alaska's statewide guidelines — Fairbanks North Star Borough courts apply the same table as every other county. Here is the calculation, with the statute it comes from.
Where a Fairbanks case goes
A Fairbanks case is filed in the Alaska court for Fairbanks North Star Borough, which applies the state guideline below. Local practice affects timing and paperwork, not the guideline amount. Fairbanks has about 31,732 residents (Census Bureau, 2024 estimate).

Does Fairbanks have its own rule?
No. Alaska Civil Rule 90.3 applies across Alaska, so a case from Fairbanks is decided by the same numbers as one filed anywhere else in the state. What changes locally is the courthouse, the clerk's procedure and how long the docket takes — not the amount.
What the statute says
Alaska Civil Rule 90.3 — Alaska child support (Civil Rule 90.3, primary custody). Rule 90.3 applies 20% for one child, 27% for two, 33% for three, plus 3% for each additional child, to adjusted annual income — capped at $138,000 a year ($11,500/month). This is the primary-custody formula; shared custody (each parent 30%+ of overnights) uses a different calculation.
