Small DCA Contributions Can Be Eaten by Fees

DCA reduces timing pressure, but it does not cancel the impact of fees.

Why this lesson matters

DCA reduces timing pressure, but it does not cancel the impact of fees.

The core idea

DCA spreads entry over time, but it does not remove trading fees or fund charges.
The smaller the contribution, the bigger the drag from fixed fees on the amount that actually gets invested.
Review trading, fund, and account costs before locking in a small monthly plan.

Practical example

A monthly DCA plan with a small contribution can lose a noticeable percentage to fixed dealing fees, while a less frequent larger contribution may be more efficient.

Common mistakes to avoid

Assuming consistency makes fees irrelevant.
Using very small installments without calculating fixed costs.
Locking in a schedule before reviewing full account and fund charges.

What to do next

It helps you judge whether your recurring plan is building steadily or silently leaking value through fees.

Important caution

Regular contributions do not mean every frequency is efficient; check the cost before relying on it.
