Resource Mix Cost Calculator
Find the blended hourly cost of a junior, mid and senior delivery mix.
In short
Find the blended hourly cost of a junior, mid and senior delivery mix.
Formula: Blended cost per hour = Σ (Share of hours_i × Loaded cost per hour_i); Total cost = Blended cost × Total hours
What this calculator does
The three shares must add up to 100%, so the weighting is always complete and explicit.
Use it to turn Currency, Total project hours, Junior share of hours, Junior loaded cost per hour, and the other shown inputs into a checked result you can compare, copy, or rerun with different assumptions.
The page shows the formula, a numeric worked example, and the assumptions that affect this professional & industry calculation.
Inputs and what they mean
- Currency
- — Amounts are shown in the currency you pick. No exchange rate is applied..
- Total project hours
- — number value.
- Junior share of hours
- — number value.
- Junior loaded cost per hour
- — number value.
- Mid-level share of hours
- — number value.
- Mid-level loaded cost per hour
- — number value.
- Senior share of hours
- — number value.
- Senior loaded cost per hour
- — number value.
How to use it
- Enter your own figures — the calculator never fills in a rate, price or benchmark for you.
- Press Calculate to see the result.
- Read the formula, variables, assumptions and source below the result before you rely on it.
Formula
Blended cost per hour = Σ (Share of hours_i × Loaded cost per hour_i); Total cost = Blended cost × Total hours.
Inputs used: Currency, Total project hours, Junior share of hours, Junior loaded cost per hour, Mid-level share of hours, Mid-level loaded cost per hour, Senior share of hours, Senior loaded cost per hour.
Edge handling: Total project hours is required.; Total project hours cannot be negative.; Total project hours must be no more than 1000000.; Junior share of hours is required.; Junior share of hours cannot be negative..
Worked example
A 30 / 50 / 20 delivery mix over 1,000 hours
- Start with Currency: USD, Total project hours: 1000, Junior share of hours: 30, Junior loaded cost per hour: 55, Mid-level share of hours: 50, Mid-level loaded cost per hour: 85.
- Apply the method: Blended cost per hour = Σ (Share of hours_i × Loaded cost per hour_i); Total cost = Blended cost × Total hours.
- The blended cost is weighted by hours, not a simple average.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Limitations and assumptions
- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this resource mix cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.

Common questions
Where does this formula come from?
OpenStax, Principles of Accounting Volume 2: Managerial Accounting — job order costing, cost-plus pricing, margin and markup. See the source link on this page.
What kind of calculation is this?
A weighted average of loaded costs, weighted by each level's share of the hours — never a simple average. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
What are its limits?
A constant mix; phased projects with a changing mix should be calculated phase by phase. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
How do I use the Resource Mix Cost Calculator?
Enter the required values for Currency, Total project hours, Junior share of hours, Junior loaded cost per hour, Mid-level share of hours, and the other fields shown. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.
What formula does the Resource Mix Cost Calculator use?
Blended cost per hour = Σ (Share of hours_i × Loaded cost per hour_i); Total cost = Blended cost × Total hours The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
Can the Resource Mix Cost Calculator be used for exact decisions?
Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.
Formula, source and verification
A weighted average of loaded costs, weighted by each level's share of the hours — never a simple average.
The question it answers: What does our delivery team cost per hour once the seniority mix is taken into account?
The formula
Blended cost per hour = Σ (Share of hours_i × Loaded cost per hour_i); Total cost = Blended cost × Total hours
- w_i — Share of hours at level i
- (%). Percentage of total hours worked at that level.
- c_i — Loaded cost per hour at level i
- (currency/h). Employer cost per hour at that level.
- H — Total project hours
- (h). Hours across all levels.
Units: Percentages; currency per hour; hours.
What kind of calculation this is
Deterministic formula. The same inputs always give the same answer. The maths is fixed and does not depend on judgement.
Method
The three shares must add up to 100%, so the weighting is always complete and explicit.
Assumptions built into the result
- Mathematical: The mix stays constant across the project.
Figures this calculator will never guess for you
- No industry-average rate, margin, overhead or ticket volume is inserted.
- No optional component is filled in on the user's behalf.
- No standard seniority mix is assumed.
Limitations
- A constant mix; phased projects with a changing mix should be calculated phase by phase.
