Details
Steps
Calculated total recurring deposits: 60 payments × $500.00 = $30,000.00.
Determined periodic compounding rate: r = 10% / 12 periods = 0.8333% per period.
Applied Future Value of Ordinary Annuity: FV = P × [ (1 + r)^N - 1 ] / r = $38,718.54.
Computed net capital gain: $38,718.54 - $30,000.00 = +$8,718.54 (+29.06% ROI).
Quick Answer & Understanding Your Result
A Dollar-Cost Averaging (DCA) Calculator models long-term wealth accumulation by dividing total capital across regular periodic purchases (daily, weekly, or monthly) to mitigate market volatility and eliminate emotional timing risks.
Core Benefits of Dollar-Cost Averaging
- Automated Market Volatility Smoothing: Automatically buys more shares when market prices drop and fewer shares when prices peak, lowering average cost per unit.
- Elimination of Emotional Market Timing: Removes the stress and financial hazard of trying to 'time the market bottom'.
- Continuous Compound Growth: Periodic contributions continually earn exponential compound interest via reinvested dividends and capital gains.
- Comparison vs. Lump-Sum Investing: Evaluates whether steady periodic deposits outperform an all-in lump sum under historical market regimes.
Formula & Calculation Logic
Mathematical FormulaCalculation methodology:
- P is recurring deposit amount, r is periodic interest rate (annual rate / periods per year), and N is total installment count.
Step-by-Step Guide
Enter Recurring Contribution
Specify how much capital you intend to deposit in each installment.
Select Contribution Frequency
Choose whether you invest daily, weekly, every 2 weeks, or monthly.
Set Investment Duration & Expected Return
Define your holding horizon in months and historical annualized growth rate (e.g. 10% for S&P 500).
Analyze Growth & Lump-Sum Comparison
Inspect your future portfolio value, total net profit, and comparative lump-sum benchmark.
Worked Examples Table
| Example | Input Values | Calculated Result | Explanation |
|---|---|---|---|
| Monthly S&P 500 Index ($500/mo, 5 Years @ 10%) | Depositing $500 monthly across 5 years yields $38,719.12, generating over $8,700 in pure compound interest. | ||
| Weekly Bitcoin DCA ($50/week, 2 Years @ 25%) | 104 weekly installments of $50 accumulate to $6,692.64 under a 25% annualized crypto expansion assumption. |
