How long your microwave usually lasts, and what replacing it tends to cost.
Usually 9 to 10 years. Where yours sits in that range depends on when it went in and how it's been looked after, which is why the install year is the most useful thing to write down. Something past its typical life isn't due for replacing on that account: most things are run until they fail. It's a reason to put money aside, not to spend it.
Roughly $200 to $700 installed in the U.S. Treat it as a range for budgeting until you have a quote.
