Calculate how much your investment will be worth at a future date. Enter your present value, annual interest rate, number of years, and optional periodic deposits to see your future value, total deposits made, and total interest earned — plus a full year-by-year growth schedule.

Future value is the worth of a current sum of money at a specified date in the future, assuming a given rate of growth or interest. It accounts for the compounding of interest over time, meaning your investment earns returns on both the original principal and previously earned interest.
The basic future value formula is FV = PV × (1 + r/m)^(m×t), where PV is the present value, r is the annual interest rate, m is the number of compounding periods per year, and t is the number of years. When periodic deposits are included, the annuity formula is added: FV_annuity = PMT × [((1 + r/m)^(m×t) - 1) / (r/m)].
Compounding frequency refers to how often interest is calculated and added to your balance each year. More frequent compounding (e.g., monthly vs. annually) results in slightly higher returns because you earn interest on interest more often. Common frequencies include annually, quarterly, monthly, and daily.
An ordinary annuity (end of period) means deposits are made at the end of each period, which is the most common scenario. An annuity due (beginning of period) means deposits are made at the start of each period. Annuity due deposits have slightly more time to compound, resulting in a higher future value.
Regular contributions significantly accelerate investment growth due to compound interest. Even small, consistent deposits can add up substantially over a long time horizon. For example, depositing $100 per month over 20 years at 7% annual interest can add tens of thousands of dollars to your final balance beyond the growth of the initial principal alone.
Yes. By entering your current savings as the present value, your expected annual return, the number of years until retirement, and your monthly contribution, you can estimate how much your retirement portfolio could be worth. Keep in mind this calculator assumes a constant rate of return and does not account for taxes or inflation.
Present value (PV) is what a future sum of money is worth today, discounted at a given interest rate. Future value (FV) is the reverse — it tells you what a current sum will grow to at a future date. The two concepts are mathematically inverse: PV = FV / (1 + r)^t.
No, this calculator uses nominal interest rates and does not adjust for inflation. To get an inflation-adjusted (real) future value, you can subtract the expected inflation rate from your interest rate before entering it. For example, if your expected return is 7% and inflation is 3%, use 4% as your effective rate.
