FAQ
- What compounding frequency does this calculator use?
- It uses monthly compounding. The annual return rate is divided by 12 to get the monthly rate, and contributions are treated as end-of-month payments (ordinary annuity).
- How is the future value calculated?
- The total future value is the sum of two parts: the lump-sum future value (FV = P * (1 + r)^n) and the annuity future value for monthly contributions (FV = C * ((1 + r)^n - 1) / r), where r is the monthly rate and n is the total number of months.
- Is my data sent anywhere?
- No. All calculations run entirely in your browser; nothing is uploaded or stored.
