Water pooling around the base, or hot water arriving scalding, is a same-day call. A tank that is only cold can wait for morning. If it is actively flooding, close the cold shut-off valve on top of the tank first.
General guidance, not advice for your specific situation. We do not publish cost estimates: almost no contractor here lists their rates publicly, so any figure we printed would be a guess you might plan around. Ask two of them.

Eight to twelve years is typical. Beyond that the risk is less that it stops working and more that it fails wet — a tank at the end of its life tends to announce itself by leaking, not by going cold, and where it sits in the house decides how expensive that morning is.
Sediment settling in the bottom of the tank takes up volume that used to hold water and insulates the burner from it. A failed dip tube causes the same symptom by letting incoming cold mix straight into the hot outlet. Both are worth diagnosing before assuming the tank is finished.
Tankless units last longer and never run out, but they cost more up front, often need venting and gas supply changes, and in hard water want descaling on a schedule. The honest answer depends on how many people shower at once in your house and whether the venting route is straightforward — which is a question for whoever looks at it, not one this page can answer.
Water pooling under the tank is a failing tank, not a repairable drip, and it does not get better. Shut the water supply to it and call the same day. A finished basement turns a next-week job into an insurance claim.
