Accounting Firm Capacity & Realization Calculator
Free, instant, no signup. Adjust the inputs and the numbers update live. Every result is a planning estimate.
Every point of realization you recover is billed work you already did — pure margin, no new clients required.
The math, in plain terms.
Raw capacity is billable staff times billable hours per week times working weeks. It's the theoretical ceiling if every billable hour were collected at full rate.
Realization is the share of billed work you actually collect at rate — write-downs, scope creep, and slow chasing erode it. Multiply raw capacity by realization to get realistic revenue capacity.
The gap between full-rate revenue and realized revenue is money left on the table for work already performed. Recovering even a few points of realization — through tighter document collection, faster month-end close, and cleaner engagement scoping — is often larger than winning a new client.
Questions, answered.
What is a good realization rate for an accounting firm?
Many small firms sit around 80–90%. The exact target varies by service mix; the point of this tool is to quantify the dollar impact of moving it, not to prescribe a number.
How do I improve realization?
Common levers: scope engagements clearly up front, collect client documents on a schedule instead of ad hoc, shorten month-end close, and flag anomalies before they become rework. All are firm-side operations, not the accounting itself.
Is this financial advice?
No. It's a planning estimate of capacity mechanics and excludes taxes, non-billable overhead, and owner compensation. Verify against your own practice-management data.
From spreadsheet to system.
The realization gap is firm-side operations leaking margin — the exact work The Practice OS systematizes: scheduled document chasing, month-end-readiness reads, and clean engagement scoping.
