Razor-and-Blades Model
Also known as: Bait and Hook, Tied Products Model, Installed Base Model
A business model where a base product (razor) is sold at low cost or given away, creating a captive market for high-margin consumables or complementary products (blades) that generate ongoing revenue.
Quick Reference
Memory Aid
Sell the razor cheap, profit on the blades. Low entry cost + high-margin consumables = lifetime revenue.
TL;DR
Sell the base product at low/no margin to build an installed base. Generate high-margin recurring revenue from consumables. Balance lock-in with customer value to prevent resentment and disruption.
What Is Razor-and-Blades Model?
Sell the 'razor' cheap (or free) to lock in customers, then make money on the 'blades' — the consumables they keep buying. Printers and ink, game consoles and games, Keurig machines and pods all follow this model.
The Original Razor King
We want to make the razor so cheap that every man will buy one. Then we will make our profit on the blades.
— King C. Gillette, founder of The Gillette Company, circa 1904
The model works by creating switching costs through the installed base. Once a customer owns the razor, they're locked into buying compatible blades. The key is that the razor creates ongoing demand for blades, and the blades generate high margins that more than compensate for the razor subsidy. The reverse razor-and-blades model (expensive razor, cheap blades) also exists — Apple sells expensive iPhones and offers cheap/free services to increase device value.
Razor vs. Blades Economics
Comparing the economics of the base product versus the consumable across common razor-and-blades businesses.
| Business | Razor (Base Product) | Blades (Consumable) | Blade Margin |

Origin & Context
Gillette popularized the model by selling razors cheaply and profiting from blade refills. The model has since been adopted across industries from printers (cheap printers, expensive ink) to gaming consoles (subsidized hardware, profitable games).
Core Components
The Razor (Base Product)
A low-cost or subsidized product that creates demand for consumables.
Example
A Keurig coffee machine sold at cost ($80-150) to create demand for K-Cup pods.
The Blades (Consumables)
High-margin recurring purchases required to use the base product.
Example
K-Cup pods at $0.50-1.00 each with 60-70% margins — a customer might buy 1,000+ pods over the machine's lifetime.
Lock-In Mechanism
What prevents customers from using competitor consumables.
Example
Proprietary pod format, DRM on printer cartridges, or incompatible game formats.
The reverse model is equally powerful. Apple sells expensive 'razors' (iPhones) and cheap 'blades' (apps, services) — the cheap blades make the expensive razor more valuable, justifying the premium price.
When to Use Razor-and-Blades Model
Consumer electronics monetization
Problem it solves: Creates ongoing revenue from a one-time hardware sale.
Real-World Application
HP printers are sold at or below cost. Ink cartridges generate the real profit — HP's printing supplies have 60%+ margins.
Gaming industry
Problem it solves: Subsidizes expensive hardware to build an installed base for software sales.
Real-World Application
Sony sells PlayStation consoles near cost but earns 30% on every game sold through its store — with millions of games sold per year.
Lock-in can create customer resentment. If blade prices feel exploitative, customers will seek alternatives or switch platforms entirely. Balance margin extraction with customer value.
How to Apply Razor-and-Blades Model: Step by Step
Before You Start
- →A product with ongoing consumable or complementary needs
- →Ability to create lock-in without alienating customers
- →Sufficient margin on 'blades' to subsidize the 'razor'
Identify Razor and Blades
Determine which product is the base (razor) and which are the consumables (blades).
Tips
- ✓The blades must be genuinely needed, not forced
Common Mistakes
- ✗Creating artificial consumable needs that feel exploitative
Price the Razor Attractively
Set the base product price low enough to drive adoption.
Tips
- ✓Calculate how many blade cycles are needed to recoup the razor subsidy
Common Mistakes
- ✗Subsidizing the razor too deeply without confidence in blade attachment rates
Create Appropriate Lock-In
Build switching costs that keep customers in the ecosystem.
Tips
- ✓Lock-in should feel like value (ecosystem benefits), not like a trap
Common Mistakes
- ✗Creating lock-in that feels punitive — this generates resentment
Optimize Blade Economics
Maximize blade margins while maintaining perceived value.
Tips
- ✓Monitor competitor alternatives and customer satisfaction with blade pricing
Common Mistakes
- ✗Pricing blades so high that customers find workarounds
Value & Outcomes
Primary Benefit
Creates a captive, recurring revenue stream from an installed base of customers.
Additional Benefits
- ✓Low-cost base product drives rapid adoption
- ✓High margins on consumables compound over the customer's lifetime
What You'll Learn
- →How to design razor-and-blades pricing
- →How to balance lock-in with customer satisfaction
Typical Outcomes
Best Practices
📋 Preparation
- •Model the full economics: razor subsidy + blade margins × lifetime purchases
- •Assess competitive blade alternatives
🚀 Execution
- •Price blades to maintain strong margins without feeling exploitative
- •Build genuine value in the ecosystem
🔄 Follow-Up
- •Monitor blade attachment rates and blade-to-razor ratios
- •Watch for competitor disruption of the blade business
💎 Pro Tips
- •Dollar Shave Club disrupted Gillette's blade model by offering lower-priced blades direct-to-consumer — proving that overly aggressive blade pricing creates disruption vulnerability
Nespresso's Premium Razor-and-Blades
Nespresso sells coffee machines at modest margins ($150-500) but generates enormous recurring revenue from proprietary aluminum capsules priced at $0.70-1.20 each — roughly $50-70 per kilogram, far exceeding the price of premium whole-bean coffee. With over 14 billion capsules sold annually, the consumable revenue dwarfs the machine business and drove Nespresso to over CHF 6 billion in annual revenue.
Limitations & Pitfalls
Customer resentment if blade prices feel exploitative
Mitigation: Price blades fairly and deliver genuine value
Vulnerable to third-party blade competitors
Mitigation: Build genuine quality and ecosystem advantages, not just lock-in
