What Is a Blended Rate?

How blended rate works

A blended rate combines the costs of multiple skill levels into one hourly figure, so a senior at $150/hr and a junior at $60/hr working equal hours bill at $105/hr instead of two separate line items. You calculate it as a weighted average: multiply each person's rate by their share of the hours, then sum the results. The blend is even only when the hours split evenly; a project that is 70% senior time and 30% junior time on those same rates blends to $123/hr, not $105/hr.

Blended rates apply when you staff a team or subcontract part of an engagement and want to quote the client a single, simple number. Agencies and freelancers who hire collaborators use them to hide internal cost structure and avoid renegotiating every time the staffing mix shifts. Clients prefer one rate because budgeting against $105/hr is easier than tracking four roles.

The practical implication: the blend protects your margin only if the actual hours match your assumed mix. If you quote $105/hr assuming a 50/50 split but the senior ends up doing 80% of the work, your real cost climbs toward $132/hr and you lose money on every hour. Build the blend on conservative hour estimates, lean toward the higher-cost role, and revisit the rate whenever the scope pushes more work onto senior staff. Treat the blended rate as a forecast, not a guarantee.
