How Much Revenue Are You Leaking?
Every B2B company leaks revenue. The question is: how much? Most companies don't know because they've never measured — and measuring requires either a costly manual audit or purpose-built tooling.
Our Revenue Leakage Calculator provides an estimate in 60 seconds, using industry benchmarks to project your annual leakage by category. This guide explains the methodology behind the calculator, the data sources, and how to interpret your results.
The Methodology
The calculator uses a benchmark-based estimation model:
- Industry selection determines baseline leakage rates across 6 categories. Different industries have different leak profiles — SaaS companies leak differently than manufacturing companies.
- Annual revenue determines the dollar magnitude. A 3% leak rate on $5M is $150K; on $50M, it's $1.5M.
- Customer count adjusts for billing complexity. More customers mean more billing configurations, more pricing variations, and more opportunities for errors.
The model outputs a range (P25 to P75) for each category, plus a total estimated annual leakage. The median estimate is the most likely scenario; the P75 estimate represents what companies with above-average complexity typically experience.
The Data Behind the Benchmarks
Our benchmarks are sourced from aggregated public reports and industry analyses published between 2024-2025:
- 46 metrics across 6 leak categories per industry
- 6 industries: B2B SaaS, E-Commerce, Professional Services, Healthcare, Manufacturing, Financial Services
- 160-450 companies per metric (sample sizes vary by industry and metric)
- Three percentiles: P25 (low leakage), Median (typical), P75 (high leakage)
Category Breakdown: What Gets Measured
1. Billing Errors — Industry Median: 1.2% of Revenue
Invoice miscalculations, duplicate charges, pro-ration errors, currency conversion drift. The single largest leak category for most companies. See: billing errors in subscription businesses.
2. Pricing Gaps — Industry Median: 1.5% of Revenue
Legacy discounts, tier mismatches, feature giveaways, unupdated rate cards. Often the hardest to detect because they were intentional decisions that nobody revisited.
3. Contract Compliance — Industry Median: 0.8% of Revenue
Unenforced escalation clauses, missed renewals, unbilled overages. Lives in the gap between what's in the contract and what's in the billing system.
4. Churn Leakage — Industry Median: 0.6% of Revenue
Preventable cancellations, failed payment churn, downgrade cascades. Revenue from customers who would have stayed with better recovery processes.
5. Expansion Gaps — Industry Median: 0.4% of Revenue
Missed upsell triggers, underutilized cross-sell opportunities, accounts that should be on higher tiers based on usage. Revenue from existing customers that's not being captured.
6. Operational Waste — Industry Median: 0.3% of Revenue
Duplicate vendor payments, unused licenses, process inefficiencies. Not strictly revenue leakage, but operational costs that reduce effective revenue.
Industry Benchmarks: Total Leakage Rates
- B2B SaaS: 3.8% median (P25: 2.1%, P75: 5.2%)
- Professional Services: 7.2% median (P25: 4.8%, P75: 10.1%)
- E-Commerce: 2.9% median (P25: 1.8%, P75: 4.3%)
- Healthcare: 4.5% median (P25: 2.9%, P75: 6.8%)
- Manufacturing: 3.1% median (P25: 1.9%, P75: 4.7%)
- Financial Services: 1.8% median (P25: 1.0%, P75: 2.9%)
How to Interpret Your Results
The calculator provides an estimate, not a diagnosis. Use it to:
- Quantify the opportunity: Is the potential recovery large enough to justify investigation?
- Identify focus areas: Which leak categories contribute the most to your estimated leakage?
- Build the business case: Use the estimate to justify investing in detection tooling or a formal audit.
For the precise number — which accounts are affected, how much is recoverable, and what specifically to fix — you need a transaction-level revenue leakage analysis that examines your actual billing data.
