Same EBITDA. Different businesses.

Two brands. Same 1 million in EBITDA. Same opex. Which would you rather own?

I posted this on LinkedIn earlier this week. Most people answered A pretty quickly, and I'd take A too. The why is what I want to talk about.

How they get to the same number

Option A runs a 4 percent discount rate and a 70 percent gross margin. It spends 1 million on ads to drive 5 million in net sales. EBITDA margin is 20 percent.

Option B runs a 30 percent discount rate and a 60 percent gross margin (largely due to discount rate). It spends 2.3 million on ads to drive 8 million in net sales. EBITDA margin is 12.5 percent.

Same bottom line. Almost twice the gross sales. More than twice the ad spend. Almost eighteen times the discount rate.

Business health

Both businesses make money and you could defend both as "good businesses." The difference is what each one depends on to keep working.

In Option A, customers are buying at full price, the unit economics work without a promo, and ad spend is roughly 20 percent of net sales, which leaves room to make adjustments year to year.

In Option B, the 30 percent discount is what's pulling in the volume, the ad spend amplifies that pull, and the whole P&L is built around that combination working. Run that long enough and the brand starts to drift toward white-label territory, where the discount becomes the actual offer and what people remember.

Discounting works when it's driving growth, especially in categories where the discount is buying you a customer who comes back at full margin later. Consumables, subscription, anything with strong repeat behavior.

The trouble starts when discounting stops being effective. Maybe the audience is tapped, the category cools, or customers start waiting for the next deal instead of buying. Volume drops, and you can't fix it with another promo because the promo is the thing that broke. Fixed costs don't move, margin compresses, and you end up a smaller business carrying the same opex and a deeper discount rate than where you started.

That's the death spiral concern with option B.

When B is the right call

Some of it depends on what kind of brand you want to be. The places where I've seen B work:

• Consumables, where the first-order discount is acquisition cost and the second order is full margin
• Subscription, where the trial discount converts into long-term revenue
• Categories with high repeat behavior, where blended margin improves over the customer lifetime

If you're running a business that fits one of those, B can be the right call. The math improves over time even though it looks iffy on day one.

If you're closer to single-purchase with light repeat, B is a harder bet. You're paying full acquisition cost on every order, and the discount has to pay off on that single transaction.

What I actually watch

The ratio of net sales to gross sales is worth watching more often than most teams do. It tells you a lot about quality of revenue and brand health.

The wider the gap, the more your top line is depending on discounts to keep moving.

Pull it monthly and watch the trend. If the gap is widening, that's a problem worth catching while you can still fix it.
