Question 1

Does this include contributions?

Accepted Answer

This version focuses on a single starting lump sum. If you plan recurring contributions, use a savings or annuity projection calculator.

Is this using APR or APY?

It uses an annual rate input for compounding in the formula. If your rate includes compounding frequency details, match the assumption to your widget’s definition.
