- Future-value compounding is the other direction.
Results explained
CAGR is the constant annual rate that grows start into end over those years. ROI without years is a single-period return. Deposits along the way need IRR.
Quick reference: CAGR
$10,000 → $18,500 in 5 years is about 13.1% CAGR.

FAQ
Is this APY?
Same compounding idea; APY is usually a stated product rate.
Negative end?
Not a useful CAGR — check the inputs.
Monthly deposits?
Use IRR or future value, not this two-point CAGR.
