Full stack freelancers cover more ground than any other dev role: frontend, backend, database, deployment. Clients pay for that breadth. This calculator helps you set a rate that reflects the full scope of what you actually deliver.
// frequently asked questions
Should I charge a single rate for all work or split frontend/backend rates?
A single blended rate is simpler and protects you when work shifts between layers mid-project. Some developers charge slightly more for backend or infrastructure work within a project, but this creates confusion on invoices. Set a single full stack rate that reflects your most complex work, and apply it to everything.
How do I price an MVP as a solo full stack developer?
Break the MVP into discrete modules, estimate each independently, then add 30% for integration and client iteration. Full stack solo MVPs almost always take longer than estimated because the developer is also the architect, QA, and DevOps person. Never quote an MVP as a flat "whatever it takes" arrangement. Define done clearly before quoting.
When does a product retainer make sense?
When a client has ongoing feature development and does not want to go through a hiring or re-scoping process every month. A good retainer defines a minimum number of hours, a response time commitment, and what falls inside versus outside scope. Cap the included hours explicitly: retainers without caps become full time jobs at contractor prices.
What billable percentage should I assume?
Full stack developers typically bill 60-65% of their working hours. Architecture decisions, technical debt management, and environment configuration are real work that clients do not see. Build them into your rate from the start.
