A 20% offer doesn't cost you 20%. Here's the arithmetic nobody runs before the banner goes up.
Every festive season, the same thing happens on the street where I grew up. Three clinics within four hundred metres of each other, and by the first week of October all three have a banner. Twenty percent off scaling. Free consultation. Family package.
By January, all three are quieter than they were in August.
I've spent the last few years looking at dental practices the way I used to look at a failing bridge, not at the part that's visibly broken, but at the load path that put the stress there. And discounting is the single most common thing I see clinic owners do that feels like marketing, costs like marketing, and works like the opposite of marketing.
I want to make the case properly, because the argument against discounts is usually made on vibes. It cheapens the brand. It attracts the wrong patients. Both true, and both easy to dismiss when your Tuesday is empty and rent is due on the fifth.
So let's do the arithmetic first.
The discount comes out of profit, not revenue
Here's the thing almost nobody works out before the banner goes up: a price cut doesn't come off your revenue. It comes off your contribution, what's left after the materials, the consumables, the sterilisation, the lab bill. And that number is much smaller than your fee, which means a small percentage off the fee is a large percentage off what you keep.
Take a scaling and polishing at ₹1,500. Say your variable cost per procedure, consumables, sterilisation, the share of materials that actually gets consumed is ₹300.
Your contribution is ₹1,200.
Now take 20% off. The fee becomes ₹1,200. Your variable cost hasn't moved; it's still ₹300. Your contribution is now ₹900.
A 20% price cut has taken 25% of your margin.
To earn the same money you were earning before, you now need to do 1,200 ÷ 900 = 1.33 times the volume. Thirty-three percent more patients, in the same chair, in the same hours, just to stand still.
It gets worse as the procedure gets more complex, because the variable cost is higher. A crown at ₹8,000 with a lab and materials cost of ₹2,500 gives you ₹5,500 of contribution. Take 20% off and the fee is ₹6,400, the lab bill is still ₹2,500, and your contribution is ₹3,900.
That's a 41% increase in volume required to break even on the same offer.
Ask yourself honestly: when you put up that banner, were you expecting a 41% increase in crowns?
Chair time doesn't go on sale
Here's what makes it worse. The crown takes the same chair hours at ₹6,400 as it did at ₹8,000. The appointment doesn't shrink. Your assistant's time doesn't shrink. The sterilisation cycle doesn't shrink.
Revenue per chair hour is the number that actually determines whether a practice is profitable, and a discount attacks it directly. You have a fixed quantity of chair hours per month. That's your entire inventory. When you discount, you are selling your only scarce resource at a lower rate and hoping volume makes up the difference, in a business where volume is capped by the number of hours you can physically work.
A hotel can sell a room at 40% off because the room existed whether or not anyone slept in it. You are not selling rooms. You are selling your hands, for a finite number of hours a week, and there is no version of this where you work 41% harder for the same money and call it growth.
You are not creating demand. You are rescheduling it.
The second cost is subtler and more permanent.
When you run a Diwali offer, some of the patients who come in were going to come in anyway. They had a scaling due in November. They saw the banner in October. They came in October, at 20% off.
You didn't create that appointment. You moved it, from a full-fee month into a discount month. And you taught that patient something they will not unlearn: this clinic has sales. If I wait, I pay less.
Run the offer twice and you've built a customer base that defers. Now your full-fee months get quieter, which makes the next offer feel more necessary, which trains the behaviour harder. I've watched practices walk into this and describe the result as a seasonal slowdown, as though the seasons were doing it.
Nothing about that is seasonal. It is a pricing pattern the clinic taught its own patients.
The patients a discount brings are the ones you can least afford
The third cost is selection.
A discount doesn't advertise to everyone equally. It advertises loudest to the people for whom price is the deciding factor and price-led patients behave differently once they're in your chair. They accept less of the treatment plan. They defer the crown and take the temporary. They no-show at a higher rate, because there's less commitment behind a discounted booking. And when they refer, they refer other price-led patients, because what they'll tell their neighbour is the price.
So the discount works, in a narrow sense. The chair fills. But you have acquired the segment with the lowest treatment acceptance and the highest cost to serve, and you have done it by giving away margin you could have spent on almost anything else.
Meanwhile the patient who would have accepted the full treatment plan at full fee, the one whose decision was never about money, also gets the 20% off, because you can't discount selectively. You've paid to acquire the wrong patients and given a rebate to the right ones.
Your front desk pays for it afterwards
The fourth cost is the one nobody counts, and it's the one I'd worry about most.
Once a clinic has discounted, the team learns that the fee is negotiable. So does the patient. Every fee conversation at the desk becomes a negotiation, and your receptionist, who is usually the least trained and least confident person in the building on the subject of money, is the one holding the line.
They won't hold it. Not because they're bad at their job, but because you've already demonstrated that the number isn't real.
That capability, the ability to state a fee calmly and not flinch, takes months to build and about one campaign to lose. And it is worth far more to a practice than any single offer, because it applies to every patient, every day, forever.
Give away what's abundant. Never give away what's scarce.
None of this means you do nothing when the chair is empty.
But understand what a discount is actually trying to solve. It's trying to solve hesitation. And in dentistry, hesitation is almost never about money, it's about uncertainty. Will it hurt. How many visits. What if it fails. Will I be told mid-treatment that it's going to cost more.
Price is what a patient says when they don't have the words for risk.
So reduce the risk instead of the fee:
Split the payment, don't cut it. Same total, spread across visits. Costs your margin nothing and removes the single biggest practical barrier. Most clinics that discount could have simply offered instalments and kept every rupee.
Put the treatment plan in writing. What happens at each visit, what it costs, what could change it and by how much. A patient who can see the whole road is far more likely to start walking it. This costs you paper.
Warranty the work. A written guarantee on a crown for a defined period is worth more to a hesitant patient than 20% off, and it costs you only in the rare case where you'd have redone it anyway.
Give away time, not fee. A free assessment in a slot that was going to be empty costs you almost nothing, empty chair time has no salvage value. A free assessment in a fully booked week costs you a lot. The offer is the same; the economics are completely different, and almost nobody checks which one they're running.
Build a care plan, not a sale. An annual membership at a fixed monthly fee covering check-ups and hygiene does the opposite of a discount: it converts irregular, price-sensitive visits into predictable revenue and a patient who has a reason to come back.
The principle underneath all of these is the same. Give away what you have in abundance, chair time in a quiet week, information, reassurance, patience. Never give away the thing you have least of, which is margin.
The real reason clinics discount
I'll be honest about why I think this keeps happening, and it isn't ignorance.
A discount is the only growth lever a busy clinic owner can pull in an afternoon. Design a banner, post it, done. Every alternative, building a recall system, writing treatment plan templates, training the front desk on fee conversations, actually calling the four hundred patients who haven't been back in a year, takes weeks of work by someone who is already doing eight hours of clinical dentistry a day.
That's not a knowledge gap. That's a capacity gap. And it's why the answer for most single-chair and two-chair practices isn't a better marketing idea, it's getting the repetitive work off the owner's plate, so the levers that actually compound become possible to pull at all.
But that's a subject for another week.
Before the next banner goes up
Do one calculation. Take your most commonly discounted procedure. Subtract your real variable cost from the fee. That's your contribution. Now apply the discount you're considering and work out the new contribution, and divide the first by the second.
That's the volume increase the offer requires just to break even.
If the number frightens you, good. It should.
And if you can't fill the chair at full fee, a discount won't fill it either. It will just make the same empty Tuesday cost you more.
But there’s a bigger question behind all of this:
If your practice needs a discount to fill the chair, do you actually have a marketing problem, or do you have a systems problem?
That’s where I believe the conversation needs to change.
Instead of constantly asking “What offer should we run?”, dentists should be asking:
“How do I build a system that consistently brings the right patients, converts them, and brings them back, without sacrificing my margins?”

What’s the biggest discount you’ve ever offered and did you ever calculate what it actually cost you?
