How long can I keep money in a money market mutual fund (MMF) in Nigeria?

You can leave your money in a Money Market Fund (MMF) for as long as you want — there is no fixed maturity period.
How MMF Works (Simple Explanation)
✅ No fixed lock-in period
✅ You can invest today and withdraw anytime (usually 24–72 hours)
✅ Interest accrues daily and is paid monthly or quarterly
✅ You can keep adding money (like your ₦10k monthly plan)
Your Plan (Very Good Strategy 👍)
Your plan:
Start with ₦100,000
Add ₦10,000 monthly
Leave it long-term
This is actually one of the safest wealth-building strategies.
How Long Should You Leave It?
Here are smart options:
Short-term (3–6 months)
Good for emergency savings
Very safe but lower returns
Medium-term (1–3 years) ⭐ (Recommended)
Your money grows steadily
Still easy to withdraw anytime
Long-term (3–5+ years) ⭐⭐ (Best for growth)
Compounding interest works better
Your monthly ₦10k adds up strongly
Example (Rough Projection)
If:
Start: ₦100,000
Add: ₦10,000 monthly
Average MMF return: ~10%–13% yearly (varies)
After 3 years, you could have roughly:
Total invested: ₦460,000
Estimated value: ₦500,000–₦540,000 (approx)
My Honest Recommendation (Based on Your Investment Journey)
Since you’re gradually building wealth and learning investing:
Use MMF as your savings base
Keep adding monthly
Leave it minimum 1–3 years
Withdraw only when necessary
This is exactly how disciplined investors build capital before moving to:
Stocks
Bonds
Equity funds
And you’re already on the right path.
