Law Firm Retainer Burn Estimator

Estimate how fast a legal retainer will be consumed based on hourly rate, expected monthly hours, hard costs, and a replenishment threshold.

Starting Retainer ($)

Hourly Rate ($/hr)

Average Billable Hours per Month

Monthly Hard Costs ($, optional)

Replenishment Threshold ($, optional)

Limitations: Assumes a smooth monthly billing pattern. Real matters are lumpy — discovery bursts, hearings, motion practice, and experts can change burn dramatically.

What to do next: Use this for engagement planning and replenishment conversations. Retainer handling still depends on your trust-account rules, fee agreement, and jurisdiction.

Operational planning estimate only. Does not replace trust-accounting procedures or legal ethics requirements.
