How Much Will I Earn Monthly From a ₦10,000 Investment in Chapel Hill Denham Money Market Fund at 17.85% Yield in Nigeria?

Let’s break this down properly so you don’t overestimate the returns.
You mentioned a 17.85% yield on a money market fund via Chapel Hill Denham (InvestNaija). That 17.85% is annual (per year), not monthly.
Step 1: Convert annual yield to monthly
To estimate monthly return:
Step 2: Monthly gain on ₦10,000
So:
Monthly profit ≈ ₦140 – ₦160
It can fluctuate slightly depending on daily rates and fund performance.
Step 3: Important reality (most people miss this)
Money market funds don’t pay a fixed interest like a bank:
The 17.85% is a target/annualized yield, not guaranteed
Returns are calculated daily and credited periodically
Your actual monthly gain can vary slightly
Step 4: If you invest ₦10,000 every month (compounding effect)
Now this is where it gets interesting. Each month:
You add ₦10,000
You earn interest on both old + new money
So your earnings will grow like this (approx):
Month 1 → ~₦149
Month 2 → ~₦300+
Month 6 → ~₦900+
Month 12 → ~₦2,000+ monthly earning potential
To visualize the compounding structure:
Where:
� = final amount
� = total invested
� = annual rate (17.85%)
� = compounding frequency
� = time
Straight answer
₦10,000 investment → about ₦150/month initially
But with consistent monthly investing, your income scales upward over time
