Leopard geckos typically live between 10 to 20 years in captivity when provided with proper care, a suitable environment, and a healthy diet. Many can live beyond 20 years, with some males reaching over 20 years of age, and there are reports of leopard geckos living into their late 20s or even up to 38 years in exceptional cases

. In the wild, their lifespan is significantly shorter, averaging about 6 to 8 years due to environmental stressors such as predators, parasites, harsh weather, and disease

. Female leopard geckos generally have a shorter lifespan than males in captivity, often living around 10 to 15 years, partly because of the physical toll of laying eggs

. Overall, with consistent and optimal care, including a proper terrarium setup and diet, leopard geckos can be long-lived pets, often living well beyond 15 years
