What Is a Dollar-Cost Averaging Calculator?
A Dollar-Cost Averaging Calculator estimates how an
investment may grow when you contribute a fixed amount
at regular intervals.
Instead of investing all available money at one time,
dollar-cost averaging spreads contributions across
multiple investment periods.
This calculator combines your starting investment,
recurring contributions, investment frequency, assumed
return, and time horizon to estimate your future
portfolio value.
How the Dollar-Cost Averaging Calculator Works
1
Enter Your Starting Amount
Add any money that is already invested before
recurring contributions begin.
2
Set Regular Contributions
Choose how much you will invest and how
frequently contributions are made.
3
View Projected Growth
See total contributions, estimated growth,
contribution count, and future portfolio value.
Future Value of Initial Investment
Future Value =
Initial Investment × (1 + Periodic Return)Number of Periods
Future Value of Regular Contributions
Contribution Future Value =
Contribution ×
((1 + r)n − 1) ÷ r
Here, r is the return per contribution
period and n is the total number of
recurring investment periods.
When contributions are made at the beginning of each
period, the calculator gives each contribution one
additional period of modeled growth.
Dollar-Cost Averaging Example
Suppose you begin with
$5,000 and invest
$500 every month for
10 years.
Initial Investment:
$5,000
Monthly Investment:
$500
Investment Period:
10 years
Expected Annual Return:
7%
Number of Monthly Contributions:
120
Your total cash contributions would be your initial
$5,000 plus 120 monthly investments. The calculator
then estimates how both the initial amount and each
recurring contribution may grow over time.
Why Investors Use Dollar-Cost Averaging
Consistent Investing
Dollar-cost averaging creates a regular investment
schedule rather than requiring you to decide when
the market is at the perfect entry point.
Investing at Different Prices
When a fixed dollar amount is invested regularly,
that amount may buy more units when prices are lower
and fewer units when prices are higher.
Long-Term Habit Building
Regular contributions can make investing part of a
recurring savings routine and may make long-term
financial goals easier to plan.
Market Risk Still Exists
Dollar-cost averaging does not prevent losses.
Investments can decline in value, and actual returns
may differ significantly from a constant annual
return assumption.
Dollar-Cost Averaging vs. Lump-Sum Investing
Dollar-cost averaging invests money gradually over
time, while lump-sum investing places a larger amount
into the market at once.
With dollar-cost averaging, later contributions have
less time to grow because they enter the investment
at different points during the selected period.
Lump-sum investing gives the full amount exposure to
market returns immediately, but it also means the
entire amount is exposed to market movements from
the start.
Important:
This calculator uses a constant assumed investment
return for mathematical estimation. Actual markets
fluctuate and investment returns are not guaranteed.
Taxes, investment fees, trading costs, dividends,
and sequence of returns are not modeled. This tool

or financial advice.
Dollar-Cost Averaging Calculator FAQs
Dollar-cost averaging is an investment approach where you invest a fixed amount at regular intervals instead of investing the entire amount at one time. The amount invested remains consistent while the number of shares purchased can vary with market prices.
The calculator combines your initial investment with recurring contributions and applies an assumed annual return over your selected period. It estimates total contributions, investment growth, and ending portfolio value.
Yes. You can select weekly, every two weeks, monthly, quarterly, or annual contributions. The calculator adjusts the number of contribution periods and investment growth accordingly.
Yes. Contributions made at the beginning of each period have slightly more time to earn investment returns than contributions made at the end of each period.
No. Dollar-cost averaging does not eliminate investment risk or guarantee positive returns. Investment values can rise or fall, and actual market performance may differ significantly from the assumed return entered in the calculator.
No. This calculator focuses on contributions and an assumed investment return. Taxes, trading costs, fund expenses, management fees, and market volatility may affect actual results.
