answers 402
Upwork freelancer fee calculator. Applies a documented tiered marginal service-fee schedule (20%/10%/5% at $500/$10,000 cumulative per-client lifetime billing thresholds) to compute take-home pay on an invoice, correctly splitting fees across a tier boundary like a tax bracket. Platform fee policies can change; verify current rates before relying on this for financial decisions.
