Practical Example
For FV = 1,000(1.06)^51,338. Monthly payments would increase the value.
This accumulation schedule shows how a starting investment and regular contributions build value over time. It separates contributions from earned interest.
Example assumptions: 100 monthly contribution, 7% annual return, monthly compounding.
Year | Starting Amount | Total Contributions | Interest Earned | Estimated End Amount |

Note: Results are estimates, not promises. Actual growth can change because returns, fees, taxes, inflation, and market conditions may vary over time.
These investment variables tell the calculator how much you start with, how long you invest, what return you expect, and what you add.
Return rate shows the yearly growth you expect from an investment. A higher rate can increase future value, but it also brings more uncertainty.
Starting amount is the money you invest at the beginning. A larger starting amount gives compound growth more money to work with over time.
End amount means the estimated value at the end of your investment period. It includes your starting money, contributions, and earned growth.
Investment length is the number of years you keep your money invested. More time gives compound growth more chances to increase your balance.
Additional contribution is money you add after the initial investment. Regular payments can increase total contributions and future investment value.
Different investments carry different levels of risk, return potential, and liquidity. Compare each option before choosing where to put your money.
Stocks represent ownership in companies. They can offer strong long term growth, but prices can fall, and you may lose part of your investment.
Bonds let you lend money to a company or government. They often provide interest income and may carry less risk than stocks over time.
Certificates of deposit, or CDs, hold your money for a set time and pay interest. Early withdrawals may trigger penalties or reduce your earnings.
Mutual funds pool money from many investors to buy a mix of assets. They offer diversification, but the fund may charge management fees.
Exchange traded funds, or ETFs, hold a group of assets and trade like stocks. They can offer broad diversification at different costs.
Real estate can produce rental income and may grow in value. It can also require more money, time, and maintenance than other investments.
Commodities include assets such as gold, oil, and farm goods. Prices can change quickly because supply, demand, and global events affect them.
Investment growth depends on several factors, including your return rate, time, contributions, compounding, inflation, and investment fees.
Your investment return directly affects growth. A higher average return can raise future value, but markets can move up or down each year.
Time gives compound growth more room to work. A longer holding period can help small gains build into a larger investment balance over time.
Regular contributions can speed up investment growth. Adding money each month increases the amount that can earn future returns and compound.
Compounding frequency affects how often returns get added to your balance. More frequent compounding can slightly increase long term growth.
Inflation makes goods and services more costly over time. Your investment may grow in dollars while its future buying power grows more slowly.
Investment fees reduce your returns. Even small yearly fees can lower long term growth because you lose the fee and its future growth.
