How to Calculate Court Filing Fee
What is Court Filing Fee?
A court filing fee calculator estimates the mandatory fees required to initiate a legal case. Fees vary by court type (small claims, civil, family, federal) and state, ranging from $30 for small claims to $400+ for federal civil cases.
Formula
Total Filing Cost = Base Filing Fee + Service of Process Fee + Any Surcharges

Frequently Asked Questions
Can I get the filing fee back if I win?
In many cases, yes. The court can order the losing party to reimburse filing fees and court costs as part of the judgment, but collection is your responsibility.
What is in forma pauperis?
It is a fee waiver for people who cannot afford court filing fees. You submit an application showing your income is at or below 125–150% of the federal poverty level.
