Starting Investment
The amount you invest initially can provide a base on which future investment growth may build.

UNDERSTANDING THE TOOL
What is an investment calculator?
An investment calculator is a financial planning tool that estimates how an investment may grow over a selected period based on a set of assumptions.
It can help illustrate the potential impact of an initial investment, recurring contributions, investment returns and time. Instead of relying on a single future-value figure, you can change individual assumptions and compare different scenarios.
Regular Contributions
Adding money consistently can increase the amount invested and give additional contributions more time to potentially compound.
Time
A longer investment period can give compound growth more time to influence the potential value of a portfolio.
HOW TO USE THE CALCULATOR
Build a simple investment scenario in minutes
Start with numbers that are realistic for your situation. You can change the inputs at any time to compare different possibilities.
01
Enter the Starting Amount
Add the amount you currently plan to invest. If you are starting from zero, enter zero.
02
Add Regular Contributions
Enter how much you expect to add regularly and choose whether contributions are monthly, quarterly or annual.
03
Choose a Return Assumption
Enter an expected annual return to model potential investment growth. Actual returns will vary over time.
04
Set the Time Period
Select how many years you expect to keep the money invested and review the resulting estimate.
INVESTMENT CALCULATOR FORMULA
How is investment growth calculated?
The calculator uses compound-growth mathematics to estimate the potential future value of your starting investment and recurring contributions.
For a basic compound investment, the future value can be expressed as:
FV = PV × (1 + r)n
with recurring contributions calculated separately
FV is the future value, PV is the starting amount, r is the periodic rate of return and n is the number of investment periods.
PV
Starting investment
PMT
Regular contribution
r
Periodic investment return
n
Total investment periods
t
Investment timeframe
COMPOUND GROWTH
Time can matter
Investment growth can compound when returns remain invested.
WHY TIME MATTERS
Compounding can make time a powerful variable
When investment returns remain invested, future returns may be generated on both the original investment and previously earned returns.
This is why the investment period can have a meaningful impact on potential future value. Starting earlier can provide more time for growth to compound, although investment performance is never guaranteed.
01
Returns can remain invested
02
Time increases the number of compounding periods
03
Regular contributions can add to invested capital
FACTORS THAT AFFECT INVESTMENT GROWTH
Your projected result depends on several variables
Changing even one assumption can produce a different projection. Use the calculator to compare scenarios rather than relying on one fixed estimate.
Initial Investment
A larger starting balance gives more capital the opportunity to participate in potential investment growth.
Contribution Amount
Increasing regular contributions can increase the total amount invested over the selected timeframe.
Investment Return
Higher assumed returns produce higher projections, but higher potential returns generally come with different levels of risk.
Investment Period
The length of time money remains invested affects the number of periods over which potential growth can compound.
Inflation
Inflation can reduce the purchasing power of future dollars, which is why the calculator provides an inflation-adjusted estimate.
Contribution Frequency
The frequency of recurring contributions affects how often new capital is added to the investment.
USE DIFFERENT SCENARIOS
Compare possibilities instead of guessing one outcome
An investment calculator becomes more useful when you use it to compare different assumptions. For example, you can change the contribution amount to understand how increasing your savings rate may affect the projection.
You can also compare shorter and longer investment periods or different return assumptions. This helps demonstrate how sensitive a future-value estimate can be to the numbers used.
SCENARIO 01
Increase Contributions
Test how a higher recurring investment could change your projected future value.
SCENARIO 02
Invest for Longer
Compare a longer investment period and observe the effect of additional compounding periods.
SCENARIO 03
Adjust Your Assumption
Test a range of potential return assumptions instead of depending on a single projection.
COMMON INVESTMENT CALCULATOR MISTAKES
Avoid overly optimistic investment assumptions
Assuming Constant Returns
Real investments do not necessarily deliver the same return every year. Calculator projections should be treated as estimates.
Ignoring Fees and Taxes
Investment expenses and taxes can reduce actual returns and may not be fully represented in a simple calculator projection.
Forgetting Inflation
A larger future dollar amount does not necessarily mean greater purchasing power after inflation.
Focusing Only on the Final Number
Understanding contributions, growth, timeframe and assumptions is more useful than focusing only on one projected balance.

INVESTMENT CALCULATOR FAQ
Common questions about investment calculations
An investment calculator estimates the potential future value of an investment using inputs such as starting capital, recurring contributions, expected return and investment timeframe.
It applies compound-growth calculations to the initial investment and recurring contributions based on the return and timeframe you enter.
No. The result is an estimate based on the assumptions entered. Actual investment performance can be different because of market conditions, volatility, fees, taxes and other factors.
Inflation can reduce purchasing power over time. Including an inflation assumption helps provide an additional perspective on what a future investment balance may be worth in today's purchasing-power terms.
Yes. You can enter a regular contribution and select monthly, quarterly or annual contributions to model recurring investment scenarios.
It is generally more useful to compare multiple reasonable assumptions rather than relying on an aggressive return estimate. Higher projected returns can significantly change the result without guaranteeing that outcome.
