Investment Calculator with Annual Contribution Increase | Estimate Your Future Value
Model monthly investing with a yearly contribution raise to see how compound growth can increase your total portfolio value over time.
How this investment calculator works
Use this calculator to estimate the future value of an investment when your monthly contribution grows by a set percentage each year. It combines your starting balance, annual return, investment term, and contribution escalator into one long-term projection.
Formula: Each year, the balance compounds monthly and the monthly contribution rises by the selected annual increase rate before the next year begins.
Example: A $1,000 monthly contribution with a 3% annual increase becomes $1,030 in year two and $1,060.90 in year three, while the account still compounds at your assumed annual return.
- Starting value: Your current investment balance before any new deposits.
- Monthly contribution: The recurring amount you invest each month at the start of the plan.
- Annual contribution increase: The yearly percentage increase applied to your monthly contribution.
- Annual return: The assumed investment growth rate each year.
- Total investment value: The estimated ending balance after compounding and contributions.
What the result means
The projected total investment value represents how much your portfolio could be worth under the assumptions entered. It is most useful for comparing long-term investing scenarios and planning steady, automated contributions.
