Mass. Gen. Laws ch. 235 § 8
When judgment is rendered upon an award of county commissioners, a committee or referees, or upon the report of an auditor or master, or upon the verdict of a jury or the finding of a justice, interest shall be computed upon the amount of the award, report, verdict or finding from the time when made to the time the judgment is entered. Every judgment for the payment of money shall bear interest from the day of its entry at the same rate per annum as provided for prejudgment interest in such award, report, verdict or finding. The warrant or execution issued on a judgment for the payment of money shall specify the day upon which judgment is entered, and shall require the collection or satisfaction thereof with interest from the day of its entry.
