BTC ROI and CAGR formulas
(current value − initial investment) ÷ initial investment × 100%(current value ÷ initial investment)^(1 ÷ years) − 1current value − initial investmentWorked BTC holding example
If 1,000 USDT grows to 1,500 USDT over 2 years: total ROI is +50.00% but CAGR is only about +22.47% — far below dividing +50.00% by 2 years, which would overstate the annual pace.
Example result table
| Implied price | Final value | Holding years | Total ROI | Annualized CAGR |
|---|---|---|---|---|
| 117,600 | 1,500 USDT | 1 yr | +50.00% | +50.00% |
| 153,664 | 1,960 USDT | 2 yr | +96.00% | +40.00% |
| 156,800 | 2,000 USDT | 2 yr | +100.00% | +41.42% |
| 235,200 | 3,000 USDT | 3 yr | +200.00% | +44.22% |
Based on 1,000 USDT bought at the 78,400 USDT reference price: the implied price column shows the BTC unit price that scenario requires. ROI is the cumulative gain over the whole hold, while CAGR spreads it into a steady annual rate for comparison.
Reading BTC annualized returns
CAGR spreads the whole holding period into a steady compound rate for comparison only; BTC rarely compounds smoothly, so a single annualized number hides the actual path.
FAQ
How is ROI calculated for BTC?
ROI = (current value − initial investment) ÷ initial investment × 100%. For multi-year holds also use CAGR = (current value ÷ initial investment)^(1 ÷ years) − 1 so different holding periods are comparable.
What is the annualized return if BTC gains 50% over two years?
Turning 1,000 USDT into 1,500 USDT gives a +50.00% total ROI and a CAGR of about +22.47% — not 25% per year.
