How to Use This Calculator
  1. Enter the lump sum amount available if you were to invest everything at once.
  2. Set the monthly DCA amount you invest regularly.
  3. Enter your expected annual return rate and investment period in years.
  4. Review the DCA future value versus lump sum future value.
  5. Note: lump sum investing often beats DCA mathematically because money is invested sooner, but DCA reduces timing risk and builds investing discipline.

What each input means

Lump Sum Amount ($)
Total amount available if investing all at once (lump sum scenario).
Monthly DCA Amount ($)
Fixed amount to invest each month in the DCA scenario.
Expected Annual Return (%)
Expected average annual return on investment (e.g., 8% for stocks).
Investment Period (years)

What each result means

DCA Future Value ($)
Total value of your DCA investment at the end of the period.
DCA Total Invested ($)
Total amount you actually invested through monthly contributions.
DCA Total Gain ($)
Profit earned through the DCA strategy.
DCA Return (%)
Total percentage return on your DCA investment.
Lump Sum Future Value ($)
Total value if you invested everything on day one.
Lump Sum Total Gain ($)
Profit earned through the lump sum strategy.
Lump Sum Return (%)
Total percentage return on the lump sum investment.
Lump Sum Advantage ($)
How much more (or less) lump sum earns vs DCA. Positive = lump sum wins.
Break-Even Monthly DCA ($)
Monthly DCA amount needed to match the lump sum outcome.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Lump Sum Amount ($) = 60000, Monthly DCA Amount ($) = 500, Expected Annual Return (%) = 8, Investment Period (years) = 10 = 4 input(s) provided
  2. Calculate DCA Future Value
    91473.02 = $91,473.02
  3. Calculate DCA Total Invested
    DCA Total Invested = monthlyAmount * totalMonths
    60000 = $60,000
  4. Calculate DCA Total Gain
    DCA Total Gain = dcaFV - dcaTotalInvested
    31473.02 = $31,473.02
