Dollar-Cost Averaging Growth Calculator

DCA is investing a fixed dollar amount at regular intervals regardless of price. You buy more shares when prices are low and fewer when they are high, automatically. It removes the emotional and timing pressure of trying to "buy the dip" and is the default approach inside most 401(k) and recurring-investment plans.

Mathematically, lump-sum investing beats DCA about two-thirds of the time historically because markets rise more often than they fall. But DCA often beats lump-sum behaviorally because it's easier to stick with during volatility. For new contributions from ongoing income, DCA is automatic and ideal; for existing cash, the choice depends on risk tolerance.

Monthly or per-paycheck is the standard cadence and works well for most investors. More frequent (weekly or daily) reduces timing risk slightly but adds friction. Less frequent (quarterly) increases timing risk. Match cadence to income flow - automatic deductions from each paycheck are the easiest and most reliable.

DCA works best with diversified, liquid investments like index ETFs and mutual funds. It works less well with individual stocks (where business fundamentals can deteriorate permanently) and not at all with declining or speculative assets. The premise - that volatility is short-term noise around a rising trend - must hold for DCA to deliver its benefits.
