Future Value vs Monthly Investment
Formule
Dollar-Cost Averaging (DCA)
DCA involves investing a fixed amount at regular intervals, regardless of market conditions.
How DCA Works
Future Value Formula
FV = PMT x [(1+r)^n - 1] / r
Where PMT is the monthly investment, r is the monthly return, and n is total months.
DCA vs Lump Sum
Historically, lump-sum investing outperforms DCA about 2/3 of the time. However, DCA reduces the emotional risk of investing at a peak and is the natural approach for income earners.
Exemple Résolu
$500/month for 10 years at 8% annual return.
- 01Monthly return = 8% / 12 = 0.667%
- 02Total months = 120
- 03Total invested = $500 x 120 = $60,000
- 04Future value = $500 x [(1.00667)^120 - 1] / 0.00667 = $91,473
- 05Investment gains = $91,473 - $60,000 = $31,473
Questions Fréquentes
Is dollar-cost averaging a good strategy?
DCA is an excellent strategy for regular investors who receive income over time. It removes the need to time the market and enforces consistent saving discipline. It is the natural way most people invest through 401(k) and IRA contributions.
Should I lump sum invest or DCA?
If you have a lump sum available, investing it all at once historically produces higher returns about 66% of the time. If you are risk-averse or worried about timing, DCA provides smoother entry and peace of mind.
How often should I invest with DCA?
Monthly is most common and practical. More frequent investing (weekly or biweekly) has minimal mathematical advantage. The key is consistency, not frequency.
