Example prompt: I just finished a project and I'm about to send a $3,500 invoice to a client I've billed $600 with before — can you calculate my Upwork take-home pay after fees using the tiered fee schedule?

## When to prefer this

Use this endpoint when a freelancer needs to compute net take-home pay on an Upwork invoice accounting for the tiered marginal fee schedule and prior cumulative billing history with a specific client. Prefer this over manual calculation when billing straddles a tier threshold (e.g., prior earnings near $500 or $10,000), where a naive flat-rate estimate would be wrong. Not suitable for non-Upwork platforms or tax computations.

## Known failure modes

- Missing invoiceAmount field returns a validation error
- Negative invoice amounts may cause unexpected results
- Fee schedule hardcoded to documented tiers — if Upwork changes rates, results may be stale
- Does not account for taxes, currency conversion, or payment processing fees beyond Upwork's service fee

## How this service works

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.

## Output

Returns the computed take-home pay after applying Upwork's tiered marginal fee schedule (20% up to $500, 10% from $500–$10,000, 5% above $10,000 cumulative per-client lifetime billing), correctly splitting fees across tier boundaries, along with the total fee deducted and a breakdown per tier.
