# Modeling lifetime valuelifetime valueLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.Voir la définition complète → across devices, disposables and service
A surgical robot can sell for over $1 million, but Intuitive Surgical, the maker of the da Vinci system, earns the majority of its revenue not from selling robots. It comes from the disposable instruments and service contracts tied to each machine already installed in a hospital. In recent annual reports Intuitive has consistently reported that recurring revenue (instruments, accessories, and service) makes up roughly 80 percent or more of total revenue. The device is the hook. The account is the business.
This is the razor-and-blade model, and if you market medtech without modeling lifetime valuelifetime valueLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business. () at the account level, you are pricing blind.
When a capital device (the expensive machine itself, often called a "placement") lands in a hospital, it creates three distinct revenue streams:
1. The device. One-time or leased. Sometimes given at low or zero upfront cost to win the account (a "reagent rental" model, common in diagnostics).
2. Disposables / consumables. The recurring "blade." Every procedure burns single-use cartridges, reagents, catheters, or instruments.
3. Service and software. Maintenance contracts, calibration, warranties, and increasingly software subscriptions or per-test cloud fees.
Diagnostics illustrates layer 2 vividly. Companies like Roche Diagnostics and Abbott place analyzers in labs and earn on every reagent kit. The analyzer is a Trojan horse for a multi-year reagent stream.
A per-transaction view asks: "Did we make margin on this reagent order?" That question misses the point.
An account-level view asks: "Over the life of this placed device, what is the total contribution margin from device, disposables, and service, net of what it cost us to win and keep the account?"
Consider a hospital that installs a diagnostics analyzer. A single reagent order may look low-margin. But that hospital may run the analyzer for 7 years, buy reagents monthly, and renew a service contract twice.

Marketing that optimizes per-transaction margin will underinvest in placements. Marketing that optimizes account LTVLTVLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.Voir la définition complète → will happily discount the device to lock in the recurring stream.
Here is a clean, marketing-relevant structure. We use contribution margin (revenue minus variable cost), not net profit, because we are measuring marketing value, not running a full P&L.
Account LTV = (Device margin) + (Annual consumables margin x years x retention) + (Annual service margin x years x retention)
Then subtract Customer Acquisition Cost (CAC): the fully loaded sales and marketing spend to win the account (rep time, demos, clinical evaluations, trade shows, KOL engagement).
Let us model one hospital account for a mid-range surgical device. These figures are illustrative for teaching, not market data.
Recurring margin per year = $75,000 + $24,000 = $99,000
To keep it simple, apply retention as a survival factor and ignore discounting for now:
Year 1 recurring: 99,000 x 0.90^0 = 99,000
Year 2: 99,000 x 0.90^1 = 89,100
Year 3: 99,000 x 0.90^2 = 80,190
Year 4: 99,000 x 0.90^3 = 72,171
Year 5: 99,000 x 0.90^4 = 64,954
Year 6: 99,000 x 0.90^5 = 58,458
Year 7: 99,000 x 0.90^6 = 52,613

Net account LTV = 676,486, 120,000 = $556,486
The device alone contributed $160,000. The recurring layers contributed over $516,000. This is why the marketing budget should chase placements aggressively.
Note: in a rigorous model you would discount future cash flows to present value. For marketing decision-making, the survival-weighted sum above is usually enough to compare accounts and channels.
The workhorse marketing metric is LTV:CAC. In our example: 676,486 / 120,000 = 5.6:1.

Recurring revenue depends on the ability to keep selling proprietary consumables. In the US, the Food and Drug Administration (FDA) regulates devices; in the EU, the Medical Device Regulation (MDR, Regulation 2017/745) governs market access. Neither directly forbids razor-and-blade pricing, but two forces threaten the "blade":
Marketers should model retention not as a fixed number but as a variable under competitive and regulatory pressure.
