Judging from the ones in my house, about a year.

The spider life cycle progresses through three stages: the embryonic, the larval, and the nympho-imaginal.
The time between when an egg is fertilized and when the spider begins to take the shape of an adult spider is referred to as the embryonic stage. As the spider enters the larval stage, it begins to look more and more like an adult spider. It enters the larval stage as a prelarva and, through subsequent moults, reaches its larval form, a spider-shaped animal feeding off its yolk supply. After a few more moults (also called instars) body structures become differentiated. Soon, all organ systems are complete and the animal begins to hunt on its own; it has reached the nympho-imaginal stage.[2]
This stage is differentiated into two sub-stages: the nymph, or juvenile stage and the imago, or adult stage. A spider does not become sexually mature until it makes the transition from nymph to imago.[2] Once a spider has reached the imago stage, it will remain there until its death. After sexual maturity is reached, the general rule is that they stop moulting, but the females of some non-araneomorph species will continue to moult the rest of their lives.
Many spiders may only live for about a year, but a number will live two years or more, overwintering in sheltered areas. The annual influx of 'outdoor' spiders into houses in the fall is due to this search for a warm place to spend the winter. It is common for tarantulas to live around twenty years.

Most spiders typically live for about a year, although up to five to six months of this may well be spent in the egg stage.
However, there are some tarantulas that can live for as many as twenty years, and even one species has been known to survive over thirty years in captivity.
Then there are some tropical jumping spiders that only live for three months or less.

It depends on the species.... some tarantulas can live several years.. while some tiny red spiders live for just a few days

Typical garden & house spiders live only a year or so, but large tarantulas can live 15 years or more.

Not too long - I've had one in my back garden who's got quite big so I've entertained myself by dropping other spiders into it's web - they really eat anything!
Since the heavy rain the other day it's dissapeared so I'm guessing he's got old and passed away peacefully.......
.........or did I feed him to a bigger spider????

depends on the spider or if someone is going to step on it or not.
