When to use this investment calculator
Use this page for broad investing scenarios where contributions happen over time. If you only want to model a single deposit, use the lump sum investment calculator. If you need to hit a target, use the monthly investment calculator.
Formula logic
Future value = starting balance compounded over time + each contribution compounded for the time it remains invested
