Overview

InterestThing is a time value of money calculator that is based on our legacy FinFlow application.

It calculates simple, capitalized and compound interest using a wide variety of methods to calculate time between dates.

Set up and save cashflows, generate detailed schedules, and solve for unknown variables.

Additional tools include windows for comparing day count conventions, analyzing periods and days fractions, and converting between different rate types.

If you are or were a user of FinFlow, make sure you read about new capabilities and changes here.

System requirements

InterestThing requires macOS 13 Ventura or later to run.
