Revenue Leakage Calculator for Pathology Labs
Estimate how much repeat-test revenue leaks every month when patients receive a report, disappear, and book their next diagnostic need somewhere else.

Revenue leakage is the repeat-test revenue a lab never collects because patients who should return for HbA1c, thyroid, lipid, or preventive retests quietly go elsewhere instead of rebooking.
Most Indian labs sit near 16%
Serious leak
Monthly revenue leaking
₹2,59,200Missed repeat patients
144Annual leakage: ₹31,10,400
Recovery plan: retest reminders recapture 30-40% of this within 2 campaigns. Start with patients due for HbA1c, lipid, thyroid repeats.
The formula
Monthly leakage = Patients × (Target repeat % − Current repeat %) × Avg order value
- patientsPerMonth
- Patients your lab sees in a typical month
- targetRepeatRate
- Repeat-visit rate you believe is achievable with better follow-up
- currentRepeatRate
- Share of patients who actually return for a repeat test today
- avgOrderValue
- Average billing per repeat visit
Worked example
A 1,200-patient-a-month lab moving from a 16% repeat rate to a realistic 28% target uncovers 144 missed repeat visits every month. At an average ticket of ₹1,800, that is ₹2.59 lakh in leakage each month, or roughly ₹31.1 lakh a year — money already earned once through trust, now walking out the door because nobody asked patients to come back.

Questions this tool helps answer
What is revenue leakage?
Most diagnostic labs only measure walk-ins, test volume, and maybe Google reviews. The bigger problem usually hides after report delivery: patients who should come back for HbA1c, thyroid, lipid, vitamin, antenatal, or preventive follow-up simply disappear.
This calculator forces that silent retention problem into a rupee number. Once the leakage is visible, automation stops feeling like a software expense and starts looking like a revenue recovery layer.
How to calculate revenue leakage
Use conservative values. If you are unsure, understate your average order value and overstate your current repeat rate. The output is still useful because it reveals the order of magnitude of the problem.
How to reduce revenue leakage
Once you know the leakage, the next move is not more discounting. The right move is building a disciplined post-report workflow: feedback request, sentiment routing, service recovery, and timed retest reminders.
Frequently asked questions
Is this only for pathology labs?
No. The logic works for diagnostic centers, radiology chains, dental recall workflows, and chronic care clinics. The examples here are written for pathology and diagnostics because that is ReviewsFlow's core market.
What if I don't know my current repeat rate?
Start with a range. Run the calculator at 10%, 20%, and 30%. The spread usually tells you enough to decide whether fixing follow-up should be a top operating priority.
What is a good repeat rate for a pathology lab?
Most Indian labs run a 15-20% repeat rate. A well-run follow-up system with WhatsApp reminders and review routing typically pushes that to 28-35%.
How is revenue leakage different from bad debt or discount loss?
Bad debt is unpaid billing. Revenue leakage here is fully avoidable, willing revenue: patients who wanted the retest but were never reminded, so they booked it — or skipped it — somewhere else.
Does revenue leakage apply to single-branch labs or only chains?
It applies to both. Single-branch labs often leak a higher percentage because they lack a dedicated follow-up team, even though their absolute rupee number is smaller than a chain's.
