What this calculator is for

A lot of labs know they have overdue patients but cannot convert that intuition into a budget case. This tool answers a narrower question: if you run one disciplined retest reminder workflow, how much revenue can it reasonably recover?

That is the number you need for board conversations, partner discussions, and deciding whether automation pays for itself in one month or three.

Good assumptions for early-stage planning

Start with modest conversion lift assumptions. In retention work, small uplifts compound. You do not need dramatic response rates for the economics to work in your favor.

Use only truly due patients, not your full database.
Include the average realized billing per returning patient.
Count one month's tool or campaign cost even if your vendor bills quarterly.

How to read the result

If one campaign can pay back its own cost, your next question becomes operational: can your team execute this consistently every month without staff burnout? That is where ReviewsFlow's WhatsApp-first automation stack changes the economics.

Compare ROI across different cohorts such as diabetes, antenatal, preventive, and annual master health checks.
Track recovered revenue separately from net-new acquisition revenue.
Use the net figure to set a rational CAC ceiling for retention-led campaigns.

Frequently asked questions

Should I include discounts in average order value?

Yes. Use the realized value after typical offer leakage. Otherwise the ROI result will look better on paper than it feels in cash collections.

Can this be used branch-wise?

Yes. Branch-wise modeling is usually better because repeat intent, doctor network strength, and home collection adoption vary materially by location.
