How Do Horse Years Work?

Horses age faster than humans, especially early on. The first year is about 12 human years, the second adds 7 more, years 3-5 add 5 each, and after 5, it slows to 2-3 human years per horse year, depending on breed. Smaller breeds like ponies age more slowly in later years, while larger breeds age faster. Our calculator adjusts for this!

Fun Facts About Horse Aging

• Senior horses (15+) may show graying coats or dental wear.
• The oldest horse, Old Billy, lived to 62—over 150 human years!
• Ponies like Shetlands can live into their 40s, outlasting many larger breeds.
• Horses mature by 5, like a human in their mid-20s.
