About this calculator
The Crypto ROI Calculator turns a purchase into plain numbers: how many coins you bought, what they are worth now, the profit or loss after fees, the return on investment and the equivalent yearly growth rate. It handles both a one-time purchase and a regular monthly buying plan, known as dollar-cost averaging.
Cryptocurrency prices swing violently, so a calculator cannot predict anything. What it can do is show you the maths of a trade you have made or are considering, including the fee drag that most people forget. Nothing here is investment advice.
How to use it
- Choose Lump Sum for a single purchase or DCA (Regular) for monthly buying.
- For a lump sum, enter the Investment Amount, the Buy Price and the Current or Sell Price per coin.
- Enter the holding period in years and months and the Transaction Fee percentage.
- Read the coins bought, current value, profit or loss, ROI, CAGR and fees paid.
- For DCA, enter the monthly amount, duration, starting price, current price and price trend.
How the figures are calculated
Coins = (Investment − fee) ÷ Buy price. Value = Coins × Sell price. ROI = (Value − Cost) ÷ Cost. CAGR = (Value ÷ Cost)1/years − 1, using the holding period in years including the months you enter.
Worked example
$1,000 in a coin bought at $20,000 and worth $65,000 after 2.5 years, 0.1% fee
| Coins bought | 0.04995 |
| Current value | $3,247 |
| Profit | $2,244 |
| ROI | 224.4% |
| CAGR | 60.1% a year |
| Fees paid | $4.25 |
A 225% gain over 2.5 years is a 60% annual rate. Crypto rarely moves in a straight line, so the real path may have included drops of 50% or more.
Tips and common mistakes
- Never invest money you cannot afford to lose. Prices can fall 70% or more.
- Fees on both entry and exit add up. A 1% fee each way costs about 2% of your capital.
- In India, gains on virtual digital assets are taxed at a flat 30% with no loss set-off, plus 1% TDS on transfers. Factor that into your real return.
- Dollar-cost averaging reduces timing risk but does not guarantee a profit.
- Past performance says nothing about future results.
Frequently asked questions
What is ROI?
Return on investment is profit divided by the amount invested, shown as a percentage.
What is dollar-cost averaging?
It means buying a fixed amount at regular intervals regardless of price. You buy more coins when prices are low and fewer when they are high, which smooths your average cost.
Does the tool include taxes?
No. Indian tax on crypto gains is 30% plus cess, and TDS of 1% applies on transfers. Subtract those for a realistic figure.
Why is CAGR shown?
ROI alone ignores time. A 100% gain in six months is very different from 100% in six years. CAGR puts them on one scale.
Can I use it for stocks or gold?
Yes. The maths works for any asset that has a buy price, a sell price and a holding period.
Is this financial advice?
No. It is a calculator for educational use. Crypto is highly volatile and unregulated in many respects.
