Most freelancers undercharge because they set rates early in their careers and never systematically review them as skills and demand grow.

Raise rates when demand exceeds capacity, when your expertise has clearly increased, or when rising costs make current rates unsustainable.

Communicate a rate increase in terms of value and outcomes, not apologies, and give clients advance notice and a clear effective date.

Offer existing clients a transition, such as honouring current rates for ongoing work until a set date, to preserve relationships.

Expect some clients to leave, and treat that as healthy filtering, since clients who value only the lowest price are rarely the best long-term fit.
