A common formula is: Effective rate = relevant matter revenue ÷ relevant recorded hours. The firm must define both terms so users know what the metric means.
Choose the Revenue Basis
Possible numerators include standard value, amount billed, net billed fees, collected fees, flat fee, or net collected fees. Label the metric clearly.
Choose the Hour Basis
Possible denominators include billable hours, all client-related hours, lawyer-and-paralegal hours, or another defined effort set. Consistency matters more than one universal definition.
Hourly Matter Example
If 20 hours were recorded, $9,000 was billed, and $8,500 was collected, the collected effective rate is $8,500 ÷ 20 = $425 per hour.
Flat-Fee Matter Example
If a flat fee is $12,000 and the matter required 30 relevant hours, the effective rate is $400 per hour. If a comparable matter requires 60 hours, the same fee produces a $200 effective rate. That signals different effort, not automatically a loss.
Effective Rate Is Not Profit
Profit also depends on labor cost, role mix, expenses, overhead, write-offs, and collections. A high effective rate can coexist with high delivery cost.
Compare Similar Matters
Use effective rate to compare similar matter types, scopes, staffing models, and fee arrangements. Avoid comparing unrelated work.
Use by Matter Phase
For phased fees, effective rate by phase can reveal underestimated work, high-value phases, scope expansion, or staffing issues.
Role Mix Matters
A $400 effective rate can have different economics depending on whether the work is partner-heavy, associate-heavy, or supported by paralegals. Combine the rate with internal cost data.
Trend Over Time
Track whether effective rate changes because of pricing, efficiency, scope, staffing, write-downs, or collections. One number without context can be misleading.
Use in Pricing
Effective-rate history can support future pricing, but strategic pricing also considers client value, risk, market, competition, and service design.
How MIRA Fits
MIRA can improve the recorded-hours side of the calculation by capturing billable and non-billable activity and organizing reviewed time by matter. It does not determine fee, cost, or profit by itself.

Frequently Asked Questions
What is an effective rate?
It is a defined fee or revenue amount divided by a defined set of recorded hours.
Should firms use billed or collected revenue?
Either can be useful, but the metric must be labeled consistently.
Is effective rate profitability?
No. Profit requires cost and expense data.
Why does timekeeping quality matter?
Missing hours can artificially inflate the apparent effective rate.
