This tool helps entrepreneurs, e-commerce sellers, and small business owners estimate uncollected revenue from operational gaps.
It calculates potential losses from missed invoices, underpriced orders, and uncollected fees.
Use it to identify areas to recover lost income and improve profit margins.
Leakage Breakdown by Source
How to Use This Tool
Follow these steps to calculate your business’s revenue leakage:
- Enter your total monthly revenue in the input field, and select your operating currency from the dropdown.
- Input the total value of each revenue leakage source over the last month: missed invoices, underpriced orders, uncollected fees, subscription churn, and return/refund losses.
- Select your typical leakage recovery rate from the dropdown (the percentage of lost revenue you usually recover).
- Click the Calculate button to view your detailed leakage breakdown.
- Use the Reset button to clear all inputs and run a new calculation.
Formula and Logic
Revenue leakage is calculated by summing all identified sources of uncollected or lost revenue, then adjusting for your typical recovery rate. The core formulas used are:
- Total Revenue Leakage = Missed Invoices + Underpriced Orders + Uncollected Fees + Subscription Churn Loss + Return/Refund Loss
- Net Revenue Leakage = Total Leakage × (1 - (Recovery Rate ÷ 100))
- Leakage as % of Monthly Revenue = (Total Leakage ÷ Total Monthly Revenue) × 100
- Each leakage source’s share = (Source Amount ÷ Total Leakage) × 100
All values are calculated before tax, and assume leakage sources are mutually exclusive (no overlapping losses between categories).
Practical Notes
These business-specific tips will help you interpret your results accurately:
- For e-commerce sellers, include marketplace fee waivers or uncollected shipping surcharges in the Uncollected Fees category.
- Small business owners should cross-reference missed invoices with their accounts receivable aging report to ensure accuracy.
- Traders and B2B businesses should include uncollected late payment penalties in the Missed Invoices category.
- A leakage rate above 5% of monthly revenue is considered high for most small businesses, per common SMB benchmarks.
- Recovery rates above 50% are typical for businesses with dedicated accounts receivable teams.
Why This Tool Is Useful
Revenue leakage often goes unnoticed for months, eroding profit margins over time. This tool helps you:
- Identify which operational gaps are costing your business the most revenue.
- Prioritize fixes (e.g., improving invoicing processes vs. adjusting pricing) based on leakage size.
- Track leakage trends month-over-month to measure the impact of operational changes.
- Build more accurate revenue projections by accounting for expected losses.
Frequently Asked Questions
What counts as a missed invoice?
Missed invoices include any billable work or products not invoiced to customers, invoices sent but not followed up on past 90 days, and invoices with incorrect amounts that were never corrected.
How do I calculate underpriced orders?
Compare the actual sale price of each order to your recommended minimum price (including cost of goods sold, overhead, and target margin). The difference between recommended and actual price, summed across all underpriced orders, is your underpriced order total.
Is subscription churn loss included in total revenue?
Total monthly revenue input should only include revenue from active subscriptions and one-time sales in the current month. Churn loss is the revenue you would have earned if canceled subscriptions had renewed, so it is a separate leakage source.
Additional Guidance
To get the most accurate results, pull data directly from your accounting software (e.g., QuickBooks, Xero) or e-commerce dashboard (e.g., Shopify, WooCommerce) rather than estimating. Run this calculation monthly to spot trends: a sudden spike in uncollected fees may indicate a payment gateway issue, while rising underpriced orders may signal a need to adjust pricing strategy. Share results with your finance team to align on recovery efforts, such as automating invoice follow-ups or adjusting minimum order prices.
