RescueLink ROI Calculator
Stop reading illustrations and run the model on your own office. Enter your patient volume, capture rate, recurring value, and retention, and see an estimate of the recurring revenue your dry eye program could build over five years. Everything below is illustrative and stays in your browser.
Key Takeaways
- This calculator runs the same compounding model as the financial arc, on your inputs.
- Four inputs drive it: new patients per month, capture rate, recurring value per patient, and retention.
- Retention is usually the biggest lever, so try changing it and watch the five-year total move.
- Results are illustrative estimates from your assumptions, not projections or guarantees.
- Nothing you enter is saved or sent anywhere. The math runs entirely in your browser.
Quick Answer
Enter four numbers and the calculator models how your recurring dry eye revenue could compound over five years: new patients per month, the share who accept and buy a plan, the recurring value each patient represents per year, and how many stay on therapy year over year. It applies retention to a growing base, the same way a real recurring program behaves. The output is an illustrative estimate based on what you enter, not a promise of results.

Illustrative estimate only, based on the values you enter. Active base applies your retention rate to the prior year plus that year's new patients. Not a projection, guarantee, or financial advice.
How the Model Works
Each year, the calculator keeps a share of last year's patients, set by your retention rate, and adds that year's new engaged patients on top. It multiplies the resulting active base by your recurring value to get that year's revenue, then sums five years. It is the same compounding logic a real recurring program follows, which is why retention has such an outsized effect on the five-year figure.
Because dry eye is chronic and managed over the long term (TFOS DEWS III), a treated patient base persists year to year rather than resetting, which is the assumption the compounding model rests on. The estimate it produces is illustrative and depends entirely on the inputs you provide.
Turn the Estimate Into Reality
The model assumes a working recurring layer. RescueLink is what creates it: personalized product sent to patients, one-tap ordering, same-day shipping, and auto-ship that protects the retention number doing the heavy lifting above. Free for providers, active in minutes.
DER Clinical Pearl
Run the calculator twice: once at your current retention, once a little higher. The gap between the two five-year totals is the dollar value of getting patients onto auto-ship and keeping them there. That number is usually larger than people expect, and it is the easiest one to move.
Frequently Asked Questions
What do the four inputs mean?
New patients per month is your dry eye intake; capture rate is the share who accept a plan; recurring value is the annual recurring spend per engaged patient; retention is how many stay on year over year.
Is the result a projection for my practice?
No. It is an illustrative estimate from the numbers you enter. Real results depend on execution, pricing, and many factors the model does not capture.
Why does retention matter so much?
Because it applies to a growing base every year. A few points of retention compound across five years into a large difference in the total.
Does it include procedure revenue?
No. It models only the recurring product layer. In-office procedures would be additional and vary by payer and setting.
What recurring value should I enter?
Use your own if you have it. The default of $1,950 is an illustrative annual figure across a typical multi-product regimen.
Is my data saved?
No. The calculation runs entirely in your browser. Nothing you type is stored or transmitted.
How do I improve the numbers in practice?
Screen more patients to raise intake, present testing to raise capture, and use auto-ship to raise retention. Retention is usually the best place to start.
