Guinea Pig Age Calculator (Human Years Conversion)
Guinea pigs age much faster than humans, especially in their first year. This Guinea Pig Age Calculator lets you convert your piggie’s age into an approximate human age and see whether they’re in a young, adult or senior stage of life.
Convert your guinea pig’s age to human years
Enter your guinea pig’s age to estimate:
- Approximate “human age” equivalent
- Life stage (young, adult, senior)
- Rough percentage of typical lifespan already lived

Example
3-year-old guinea pig
- Approx. human age: often comparable to a human in their late 30s–40s.
- Life stage: mature adult, entering early senior years for many pigs.
- Focus on weight stability, dental checks and joint comfort.
Typical guinea pig lifespan & life stages
Lifespan varies with genetics, diet, housing, companionship and veterinary care. Many guinea pigs live around 5–7 years; some may live shorter or longer lives.
How to use your guinea pig’s “human age”
1. Adjust expectations by life stage
Younger pigs may be more active and skittish, while seniors may nap more and move slower. Comparing to human ages can make this easier to understand.
2. Schedule vet checks with age in mind
As your pig transitions from young adult to senior, regular vet visits and weight checks become more important to catch problems early.
3. Pair age with lifestyle upgrades
Soft bedding, easy-access hides, stable companions and gentle handling matter more as your guinea pig ages, just like comfort matters more for older humans.
