First, the percentage recouped on of your dollars spent is dependent on the overall value of your home and the comps for similar remodeled homes. With that said, Tiffany has the percentages correct, about 80% of the dollars you spend can be added to value of your home...in a more stable market.
Today, it is better to tour some homes with your agent that are like yours that have had the kitchen remodeled. Also, Let;s say that your home is worth $700,000 now. It is hard to tell what you would get back on a $100,000+ remodel without doing the homework and comparative analysis upfront.
Please let us know if you have any further questions.
Best of luck,
