Frequently Asked Questions
Can freelancers charge late fees on overdue invoices?▾
Yes — if your contract or invoice specifies a late fee policy. Without it in writing, enforcing fees is difficult. Always include your late fee terms in every contract and on every invoice before starting work.
What is the standard late fee for freelancers?▾
1.5% per month (18% annually) is the most common standard used by freelancers and small businesses in the US. Some freelancers use 2% per month. Always check your state's usury laws for maximum rates.
How do I calculate a late payment fee?▾
Multiply the invoice amount by the monthly rate, then multiply by the number of months (or use the daily rate × days overdue). Example: $2,000 invoice × 1.5% × 2 months = $60 in late fees.
What should I do before charging a late fee?▾
Send a polite payment reminder first. Many late payments are administrative oversights. Only apply late fees if payment is significantly overdue (15–30 days past due) and after at least one follow-up. Maintain the relationship while enforcing your terms.
Can I charge late fees retroactively?▾
Only if your original contract or invoice specified the late fee terms before work began. You cannot retroactively add fees that weren't disclosed. This is why including late fee language in every contract matters.
