Question 1

What is a blended rate?

Accepted Answer

A blended rate is a single weighted average hourly billing rate that represents the combined cost of an entire project team. Instead of quoting separate rates for each role, a staffing agency or consultancy calculates one rate that reflects the true average cost per hour across all team members, weighted by how many hours each role contributes.

Question 2

How do you calculate a blended rate?

Accepted Answer

Blended Rate = Total Team Cost ÷ Total Team Hours. Total Team Cost is the sum of (Headcount × Hours per week × Hourly Rate) for every role. Total Team Hours is the sum of (Headcount × Hours per week) for every role. This is a weighted average — not a simple average — so it correctly accounts for the proportion of hours each role contributes.

Question 3

What is the blended rate formula?

Accepted Answer

The formula is: Blended Rate = Σ(Headcount × Hours × Rate) ÷ Σ(Headcount × Hours). For example, 2 Senior Developers at $185/hr (40 hrs/week) and 3 Mid Developers at $120/hr (40 hrs/week) gives a blended rate of (14,800 + 14,400) ÷ 200 = $146/hr.

Question 4

What is the difference between a blended rate and a simple average rate?

Accepted Answer

A simple average adds all hourly rates and divides by the number of roles, ignoring headcount and hours. A blended rate is a weighted average that accounts for how many people fill each role and how many hours they work. The blended rate is always the correct number to use for project costing and client proposals.

Question 5

How is the client bill rate calculated from the blended rate?

Accepted Answer

Client Bill Rate = Blended Rate ÷ (1 − Margin%). For example, a blended rate of $120/hr with a 25% margin gives a bill rate of $120 ÷ 0.75 = $160/hr. Avoid multiplying the blended rate by 1.25 — that only gives a 20% margin on the bill rate, which systematically undercharges clients.

Question 6

Why does the monthly burn rate use 4.33 instead of 4?

Accepted Answer

There are 52 weeks in a year and 12 months, giving an average of 4.33 weeks per month. Using a flat 4× multiplier underestimates monthly cost by approximately 8.25%, which can mean a $20,000+ error on a large engagement. The 4.33 multiplier is the professional standard for accurate contract pricing.

Question 7

Is this blended rate calculator free to use?

Accepted Answer

Yes. BlendyRate is completely free. There is no login, no subscription, and no data is stored on any server. All calculations run entirely in your browser. You can add unlimited roles, export as CSV, copy a proposal snippet, and share via a direct link at no cost.

Question 8

Who uses a blended rate calculator?

Accepted Answer

Blended rate calculators are used by IT staffing agency account managers, managed service providers (MSPs), law firm billing partners, engineering and construction project managers, marketing agency principals, and enterprise procurement officers benchmarking vendor proposals.

Question 9

What is a blended rate in IT staffing?

Accepted Answer

In IT staffing, a blended rate is a single hourly bill rate covering a mixed team of developers, analysts, architects, and testers at different individual rates. IT staffing agencies use blended rates for government frameworks (GSA Schedule, G-Cloud), SOW engagements, and enterprise MSP contracts.

Question 10

What is a blended labor rate in construction?

Accepted Answer

In construction, a blended labor rate (also called a composite labor rate) is the weighted average hourly wage for a crew with helpers, apprentices, journeymen, and foremen at different pay grades. Construction project managers use it to estimate job costs, prepare bids, and track budget variance.

Question 11

Can I use this blended rate calculator for a law firm?

Accepted Answer

Yes. Enter partner, associate, and paralegal roles with their hourly rates and weekly hours to get the weighted average billing rate. Law firms use blended rates to quote clients on large matters, corporate retainers, and government legal frameworks. Top Am Law 100 firms averaged $1,057/hr blended in 2024.

Question 12

How do I calculate a blended rate for an RFP or SOW proposal?

Accepted Answer

List every role with headcount, weekly hours, and cost rate. Multiply headcount × hours × rate per role. Sum all role costs for total weekly cost. Sum all headcount × hours for total weekly hours. Divide total cost by total hours for the blended cost rate. Apply margin: Bill Rate = Blended Rate ÷ (1 − Margin%). BlendyRate performs all steps automatically.

Question 13

What is the difference between bill rate and blended rate?

Accepted Answer

The blended rate is your internal cost rate — what it costs per hour to deliver the team. The bill rate is what you charge the client — the blended rate plus agency margin. The blended rate is the foundation; the bill rate appears on the invoice.

Question 14

Can I share my blended rate calculation with a client?

Accepted Answer

Yes. BlendyRate generates a shareable URL encoding your complete team configuration. Anyone opening the link sees the same calculation. You can also copy a ready-to-paste proposal snippet for use in RFP responses and SOW documents.

Question 15

Does the blended rate calculator work for multiple currencies?

Accepted Answer

Yes. BlendyRate supports 15 currencies: USD, GBP, EUR, CAD, AUD, JPY, CNY, INR, BRL, SAR, TRY, KRW, SEK, PLN, and CHF. All outputs display in the correct local format including zero-decimal currencies like JPY and KRW.

Question 16

What is a weighted average billing rate?

Accepted Answer

A weighted average billing rate is another term for a blended rate — the average hourly rate for a team weighted by hours contributed per role. The term is commonly used in legal billing, consulting, and government contracting. It is calculated as: Total Billed Cost ÷ Total Billed Hours.

Question 17

How do I calculate the monthly burn rate for a project team?

Accepted Answer

Monthly Burn Rate = Weekly Team Cost × 4.33. Weekly Team Cost = Σ(Headcount × Hours/week × Rate) across all roles. The 4.33 multiplier converts weekly to monthly using 52 weeks ÷ 12 months. BlendyRate calculates both weekly and monthly burn automatically.

Question 18

Is the blended rate calculator accurate for professional proposals?

Accepted Answer

Yes. BlendyRate uses the professional-standard weighted average formula for blended rates, the margin-on-bill-rate formula for client pricing, and the 4.33 weekly multiplier for monthly burn — consistent with how staffing agencies, MSPs, law firms, and consulting firms calculate team rates for proposals, SOWs, and framework contracts.
