Model the Vampire Apocalypse
How fast would vampires take over the world? This calculator simulates exponential infection spread—the same math used for epidemics, rumors, and viral content. Adjust bites, resistance, and hunters to see different outcomes.
✨ The Fun Behind This
Why It's Fun
Vampire spread follows exponential growth—the same math as epidemics, rumors, and viral content. Each vampire creates new vampires, who create more. Without resistance or death, one vampire could theoretically infect billions within months.
How It Works
The model uses an SI (Susceptible-Infected) framework: humans become vampires when bitten. We add death rate (hunters, sunlight, garlic), gestation (delay before new vampires can bite), and resistance (bites that don't convert).
Key Insights
- ●Exponential growth — small changes in bite rate cause huge outcome differences.
- ●Death rate — hunters and sunlight can slow or reverse the outbreak.
- ●Gestation — delay before new vampires bite slows spread significantly.
- ●Resistance — some survivors mean equilibrium is possible.

🎲 Fun Facts
With 1 bite/night and no resistance, one vampire could infect billions within months.
— Exponential Math
Garlic and hunters act as decay factors—even 5% death rate significantly slows spread.
— Folklore
The same equations appear in real disease modeling—vampires are a fun way to explore them.
— Epidemiology
Vampire spread follows exponential growth—the same math as epidemics, rumors, and viral content. Each vampire creates new vampires, who create more. Without resistance or death, one vampire could theoretically infect billions within months.
📋 Key Takeaways
- • Exponential growth — small changes in bite rate cause huge outcome differences
- • Death rate — hunters and sunlight can slow or reverse the outbreak
- • Gestation — delay before new vampires bite slows spread significantly
- • Resistance — some survivors mean equilibrium is possible
🧛 Vampire Math & Epidemiology
The model uses an SI (Susceptible-Infected) framework: humans become vampires when bitten. We add death rate (hunters, sunlight, garlic), gestation (delay before new vampires can bite), and resistance (bites that don't convert). The same equations appear in real disease modeling—vampires are a fun way to explore exponential growth.
If the effective infection rate exceeds the death rate, vampires win. If death rate wins, the outbreak fizzles. At equilibrium, new infections balance vampire deaths—humans and vampires coexist (like in some vampire fiction).
