Effective Rate / Yield

Effective rate (also called yield) is the actual revenue collected per hour worked on an engagement or across a portfolio, calculated after all discounts, write-offs, and unbilled time are applied.

It is distinct from the rate card bill rate, which is the price before any reductions. The gap between the two reveals the cumulative cost of discounting, write-offs, and unlogged hours.

The formula

Effective rate = Total revenue collected / Total hours worked

A project where 800 hours were delivered and $140,000 was collected has an effective rate of $175 per hour. If the standard rate card rate for that team is $220, the effective rate reveals a 20% shortfall that the rate card would never surface on its own.

What effective rate captures

The effective rate absorbs every source of revenue erosion into a single number:

• Front-end discounts negotiated at the proposal stage
• Write-offs applied at invoicing before the invoice is sent
• Unbilled scope delivered as a courtesy and never entered as billable hours
• Fixed-fee overruns where hours worked exceeded the budget

No individual metric captures all four in isolation. Effective rate is the only figure that reflects what the firm actually collected per unit of capacity consumed.

Effective rate vs. bill rate vs. realization rate

Metric	What it measures
Bill rate	The rate card price before any reduction
Effective rate	Revenue actually collected per hour worked
Realization rate	Effective rate expressed as a percentage of bill rate

The three metrics describe the same underlying reality from different angles. Realization rate is useful for benchmarking against peer firms or internal targets because it normalizes across different rate levels. Effective rate is more useful for financial modeling because it produces a dollar figure that can be multiplied directly by planned hours.

How to use effective rate

Revenue modeling. Multiply effective rate by planned billable hours to produce a realistic revenue forecast. A plan built on standard bill rates will consistently overstate expected revenue for any firm that carries a meaningful realization gap.

Pricing decisions. Comparing effective rate by practice area, client segment, or engagement type identifies where the firm systematically under-prices or over-discounts. A practice with a strong bill rate but a low effective rate is absorbing costs through write-offs rather than managing scope.

Partner reviews. A partner whose client book has an effective rate significantly below the firm average warrants a pricing conversation. The gap may reflect legitimate relationship pricing for strategic accounts, or it may reflect a pattern of write-off discounting that bypassed the standard approval workflow.

Benchmarking. Year-over-year effective rate trends by service line reveal whether pricing power is improving or eroding, independent of changes to the published rate card.
