Invest €200 Per Month: Projections Over 10, 20 and 30 Years

€200 a month is €2,400 a year. Not a fortune. But invested consistently in index ETFs inside a French PEA, it's enough to turn an ordinary savings habit into meaningful wealth. Here are the real numbers, the right ETF, the right broker, and how to set this up in under an hour.

The projection: what €200/month actually becomes

These projections use an average annual return of 7%, close to the MSCI World's historical inflation-adjusted performance over the past 30 years. Not a guarantee — the most reasonable baseline for a World ETF over the long term.

At 10 years, gains (€10,800) represent 31% of the capital. At 30 years, they represent 71%. The earlier you start, the more compound interest does the heavy lifting. The start date matters far more than the monthly amount. See our guide to compound interest.

Which account to use for €200/month

The answer is almost always a PEA for a 5+ year horizon. After 5 years, tax on gains drops from 31.4% (flat tax) to 18.6% (social charges only). Over decades of DCA, this gap is worth thousands of euros.

A standard CTO is only relevant if you exceed the PEA contribution ceiling (€150,000) or want ETFs not eligible for a PEA (physical all-world ETFs). In that case, open a CTO as a complement. See our PEA vs CTO guide.

Which ETF to buy

One ETF is enough: a MSCI World ETF eligible for a PEA. In 2026, the top two options are:

• WPEA (iShares MSCI World Swap PEA, ISIN IE0002XZSHO1): 0.20% TER/year, ~€5 per share. Lower fees, newer fund.
• DCAM (Amundi PEA Monde, ISIN FR001400U5Q4): 0.20% TER/year, ~€5 per share. Launched late 2024, same profile as WPEA.
• CW8 (Amundi MSCI World Swap, ISIN LU1681043599): 0.38% TER/year, ~€500 per share. The historical benchmark — higher fees and share price. Worth keeping if already owned; otherwise WPEA or DCAM are better for new DCA.

With €200/month and shares at €5, you can buy exactly 40 shares without waiting to accumulate enough for a whole share like with CW8. That's a real practical advantage for monthly DCA.

Which broker for €200/month

Order fees matter a lot in monthly DCA. Over 20 years (240 orders), €1 less per order saves €240. Here's the comparison for a €200 order:

Trade Republic lets you set up a free monthly automated investment plan, so you never have to place orders manually. PEA available in France since January 2025.

How to set up your €200/month DCA, step by step

1. Open a PEA at Trade Republic, BoursoBank, or Bourse Direct. Online opening takes under 15 minutes. See our guide to opening a PEA.
2. Transfer €200 immediately after opening — the 5-year clock starts on the date of your first transfer.
3. Buy WPEA or DCAM: search the ticker in your broker's app and place a market order.
4. Set up an automatic bank transfer of €200 every month from your current account to your PEA.
5. At Trade Republic, activate the investment plan on WPEA so the order executes automatically every month at €0 in fees.
6. Ignore daily fluctuations. When markets drop, your €200 buys more shares. That's mathematically favorable over the long term.

What if markets fall?

They will. MSCI World history over 40 years includes several major crashes: 2000–2002, 2008–2009, 2020. In every case, the index recovered and reached new highs within 1 to 3 years. Monthly DCA turns every dip into a buying opportunity: with €200, you buy more shares when prices are lower. The only fatal mistake is selling during the panic.

Is €200/month enough?

Yes. €200/month invested over 30 years at 7%/year produces approximately €245,000. That's well above what most people manage to save for retirement, through consistency and time alone. Market performance does the rest.

If you can invest more, results scale proportionally: €400/month produces roughly €490,000 over 30 years. But even €100/month over 30 years yields around €122,000. The essential thing is to start — not to hit a perfect amount. See our guide to investing €100/month.
