The typical lifespan of snake plant ranges from 15 to 25 years with decent indoor care. Some push well past that mark and survive for decades in the same pot. Your snake plant is one of the longest-living houseplants you can own. Its hardy nature means you can keep it going for a very long time with minimal effort.
I know this from my own family's experience. My grandmother grew a Laurentii from a single leaf cutting in the 1980s. She passed it to my mother in 2005 after caring for it for over 20 years. My mom kept it in the same terracotta pot near her kitchen window. She watered it now and then and that was about it. That plant is still alive today at roughly 40 years old. I've seen stories like this from other snake plant owners too.
So how long do snake plants live under different conditions? In bright indirect light with proper watering, you can expect the full 20 to 25 year range at minimum. In low light with sporadic attention, your plant will still push through 10 to 15 years without much trouble. The only thing that cuts its life short fast is root rot from too much water. I've seen healthy plants die within a month when their roots sat in soggy soil.
The secret behind snake plant longevity is the rhizome system under the soil. Your plant spreads through thick stems that run just below the surface. These rhizomes push out new rosettes of leaves throughout the plant's life. Even as your older leaves yellow and die back after a few years, fresh growth keeps coming up from below. The plant replaces old growth with new shoots on a continuous cycle. This is why your snake plant can outlive most other houseplants by a wide margin.
Overwatering kills more snake plants than any other cause. Your plant's thick leaves store water for weeks at a time. You only need to water once every 2 to 3 weeks in most homes. Watering more than that creates conditions where fungal root rot takes hold fast. Using a pot without drainage makes this problem even worse and can cut years off your plant's life.
A few simple habits will add years to your snake plant's life. Repot it every 3 to 5 years to give the rhizomes fresh soil and room to spread. Pull off dead or yellowing leaves right away so your plant doesn't waste energy on dying tissue. Don't fertilize from October through February. Your plant enters dormancy during these months and feeding it causes salt buildup that hurts the roots.
I repotted my oldest snake plant last spring after four years in the same pot. The rhizome network had filled the entire container and was pushing against the sides. After moving it to a pot two inches wider, it pushed out three new leaves in just six weeks. That simple refresh gave it a second wind.
Your snake plant has the genes to live for decades with you. Give it a terracotta pot with drainage, water it less than you think it needs, and let it sit in any room with a bit of light. Do those basics and you might just pass your plant down to the next generation the way my grandmother did with hers.
