Weekly vs Monthly Investing: Which Is Better for Beginners?

If you’re wondering whether to invest weekly or monthly, you’re not alone.
One of the most common beginner questions I get is:

“How often should I invest—weekly, monthly, or just whenever I have money?”

The answer is simpler than you think—and understanding it could save you thousands over time.
Let’s break down how dollar-cost averaging works, what the difference between weekly and monthly investing really is, and what I recommend based on how I grew my net worth to $1 million by age 35.

🔁 What Is Dollar-Cost Averaging?

Dollar-cost averaging (DCA) is a strategy where you invest a fixed amount on a regular schedule—no matter what the market is doing.

Instead of trying to time the market, you simply invest consistently. For example:

  • $100 every month into a total stock market ETF
  • $25 every week into an S&P 500 index fund

Over time, this smooths out your purchase price, avoids emotional decisions, and builds wealth steadily.

💬 My Personal Strategy

When I was getting started, I didn’t have a huge sum to invest. I had just become a new dad, was living in a high-cost-of-living city, and needed to start small.

So I started with $50 every two weeks.
That small habit, automated and consistent, eventually helped me build to a $1 million net worth by 35.

Now, I invest twice a month—on autopilot. I don’t worry about market swings or try to pick the “right day.” My focus is on building wealth, not guessing.

✅ Which One Should You Use?

Here’s what I tell beginner investors:

  • If you’re paid weekly, go weekly.
  • If it’s easier to automate monthly, go monthly.
  • If you don’t know where to start, try $100/month into a total stock market ETF.
