your upwork math
the form arrives. or it doesn't. you still owe.
upwork's fee is flat 10% (for newer contracts) or 20%/10%/5% sliding scale for legacy contracts based on cumulative billing with each client. plus a $0.15 'client deposit' fee per project, plus connects (the credits you spend bidding). all of these are business expenses.
upwork's connects system requires you to pay to bid on jobs. those connects (you pay cash for them) are business expenses — but most freelancers forget to deduct them. it adds up: a $20/month connect refill is $240/year in deductions you might miss.
