How this calculator works

We solve for a constant payment each month or each year so that your starting balance, plus those payments, grows at your chosen return and compounding frequency to meet your target.

The donut shows how much of the final goal comes from your original lump sum, how much you had to add along the way, and how much is attributed to compounding.

Use it to set a realistic savings rhythm — then build the bigger picture (budget, risk, and investing) in the course.
