In six days, Hopkinton residents will vote on a proposal to build a $152 million schoolhouse, with $61 million contributed by the Massachusetts School Building Authority.

The town has floated numbers that use the “Average Hopkinton Home” value, which is $753,300. While it may be helpful to some, it’s not for anyone with a home value that is less or more than that number. Instead, voters have to do the ‘mental math’ to figure their personal tax impact.

HopNews has developed an interactive tax calculator to show property owners what their personal tax impact will be over the next decade due to the Elmwood project. Simply plug in your assessed value and the calculator will do the rest.
