Dollar-Cost Averaging

Regular deposits buy more shares when prices dip and fewer when prices rise. Over volatile markets, DCA can reduce average cost per share compared to a single lump-sum entry—though outcomes vary.

Expense Ratios Matter

A 1% annual fee compounds against you. On a $100,000 portfolio over 30 years, the difference between 0.05% and 1% fees can cost tens of thousands in lost growth.

Taxable vs Tax-Advantaged

Fund distributions in taxable accounts create annual tax drag. Hold tax-inefficient funds in IRAs or 401(k)s when possible. See IRA Calculator and 401(k) Calculator.

How It Works

  1. Enter your amounts, rates, and term in the form. Use the same units shown in the labels (dollars, years, percent).
  2. Click Calculate to run the Mutual Fund Calculator engine. Invalid or empty required fields show a clear error message.
  3. Review the summary cards for the key outputs. Expand schedules or tables when available for period-by-period detail.
  4. Copy, print, or share your scenario link. Reset the form anytime to start a fresh comparison.

Formula

Future Value with compounding: FV = P(1 + r/n)^(nt). For periodic deposits, each contribution grows from its deposit date at the same periodic rate.

FAQ

Yes. CDCalculator.io provides the Mutual Fund Calculator at no charge for personal and educational use. Results are estimates and not financial advice.
