Most microwave oven models on sale at Lowe's home improvement stores cost between $200 and $400, as of March 2015. A few models cost as little as $100 or less, while the most expensive models cost as much as $1,950.
Factors affecting a microwave oven's price include its interior capacity, cooking power and features such as sensor cooking. Built-in and over-the-counter microwave ovens tend to cost more than countertop models, though these ovens do not necessarily have any more internal space or other features than countertop models. The most expensive microwave ovens at Lowe's are built-in designs with full convection cooking capabilities.
