Crypto Calculators & Live Market Trackers

What do you want to accomplish?
Pick the scenario closest to your question and go straight to the right combination of tools.
I want to plan a long-term investment
Start with the ROI calculator to set a goal, use compound interest to model reinvested yield, then DCA to compare a regular-contribution plan against a lump sum.
I want to manage the risk on a trade
Size your position so a single loss can never exceed your risk budget, then audit the break-even price and after-fee return before you enter.
I want to understand a coin's value
Use market-cap comparison to see relative scale (not just unit price), and the converter to translate the holding into a fiat or BTC-denominated figure.
I want to follow market events
The halving countdown tracks a protocol milestone weeks or months in advance; Fear & Greed gives a daily read on crowd sentiment. Use them together for macro context.
I'm considering providing DeFi liquidity
Estimate the impermanent loss you could face from a price ratio shift, convert the position value, and compare to the ROI you'd expect from simply holding.
I'm a complete beginner
Start with Fear & Greed to understand sentiment, use the converter to make sense of crypto amounts, and explore the ROI calculator to see how compounding works.
Investment & growth calculators
Project how a holding could grow over time and compare scenarios before you commit capital. Best for long-term planning, DCA strategies and measuring expected returns against your own benchmarks.
Trade, risk & conversion
Size a position to a fixed risk budget, audit the actual after-fee result of a trade, and convert between assets at reference prices. These tools turn pre-trade intuition into concrete numbers.
Valuation & liquidity
Understand why unit price alone is misleading, and estimate the hidden cost of providing liquidity on an AMM. Essential for comparing tokens of different supply scales and for DeFi participation.
Live market trackers
Follow protocol-driven events and market-wide sentiment with data that updates automatically. These trackers require no inputs — they read the current state of the network or market.

How to get the most from these tools
Each calculator is a way to reason about a question, not a crystal ball. The numbers you get out depend entirely on the assumptions you put in, so the real value is in testing different scenarios and seeing how sensitive an outcome is to a change in price, rate or risk.
- Start with your own figures. Use realistic inputs rather than best-case numbers, and always include fees where the tool allows it.
- Test a range. Run an optimistic, a middling and a pessimistic case. A result that only works under perfect conditions is a warning sign.
- Remember what they can't see. No calculator knows future prices, regulation or liquidity. Projections assume a steady world; real crypto markets are anything but.
- Pair tools with concepts. Each tool links to plain-English glossary entries and guides so you can understand the idea behind the math.
- Use the "In practice" section. Every individual tool page includes a realistic scenario showing how a journalist or analyst would use the tool's output — read it to understand what the numbers actually mean in context.
Which tool should I use?
Planning a long-term position
Begin with the ROI calculator to project a single investment, then use compound interest to see the effect of reinvested yield and dollar-cost averaging to model regular contributions instead of a lump sum.
Managing risk on a trade
Use the position size calculator to cap how much a single losing trade can cost you, and the profit / loss calculator to check the after-fee result of a buy and sell — including the break-even price you need before any profit is possible.
Understanding value and the market
The market-cap comparison shows why unit price alone is misleading, while the Fear & Greed index and halving countdown add market-wide context. New to the basics? Start with our guide on how to read a crypto market.
Evaluating a DeFi opportunity
Run the impermanent loss calculator with the price change you'd expect across the pair you're considering, then compare that loss against the projected fee yield. Use the ROI calculator to see whether simply holding would have produced a better risk-adjusted return.
Compare every tool at a glance
Not sure where to start? This table summarises what each calculator and tracker answers, what you feed in, and what it returns. Select any tool to open it.

| ROI calculator | What return could an investment produce over time? | Initial amount, regular contribution, growth rate, years | Projected value, total invested, net growth, ROI % | Calculator |
| Compound interest | How much does reinvested yield add over time? | Principal, APY, compounding frequency, term | Future balance and total interest earned | Calculator |
| Dollar-cost averaging | How might steady, fixed-size buys grow? | Contribution, frequency, period, assumed return | Total contributed versus projected value | Calculator |
| Position size | How large a position fits my risk limit? | Account size, risk %, entry price, stop-loss | Capital at risk, units to buy, position value | Calculator |
| Profit / loss | What is my result on a trade after fees? | Buy price, sell price, quantity, fee % | Cost, proceeds, net profit or loss, return %, break-even price | Calculator |

Common questions
A few things people often ask before using the calculators and trackers.
Are the tools free to use?
Yes. Every calculator and tracker is free and needs no account or sign-in. The calculators run in your browser, so you can test as many scenarios as you like without limits.
How accurate are the projections?
The arithmetic is exact for the inputs you give it — but several of those inputs, such as a future growth rate or sell price, are assumptions about the future, not facts. A projection is a structured "what-if", not a forecast.
Because crypto is famously volatile, always run an optimistic, a middling and a pessimistic case rather than trusting a single number.
What is the difference between a calculator and a live tracker?
A calculator works only from the numbers you type in, so the same inputs always give the same answer. A live tracker — like the Fear & Greed index or the halving countdown — automatically pulls current market data, so its reading changes as the market does.
Do these tools provide financial advice?
No. They are educational tools to help you reason about a question, and nothing here is financial advice or a recommendation to buy or sell. For context on reading the wider market, see our guide on how to read a crypto market.
Which tool should a complete beginner start with?
Most people find the ROI calculator the easiest entry point because it turns a single investment into a concrete number. From there, compound interest shows the effect of reinvesting, and dollar-cost averaging models regular buying instead of one lump sum.
For live market context, the Fear & Greed index gives a simple 0–100 read on current sentiment, and the crypto converter helps make sense of fractional coin amounts in fiat terms.
Do you save the numbers I enter?
The calculators run entirely in your browser and don't ask you to sign in or hand over personal details to get a result. Treat them as a private scratchpad for testing scenarios.
How often is the live data updated?
Live data — used by the Fear & Greed index, the halving countdown and the converter — is cached and refreshed on a schedule (typically every 5–15 minutes for market prices; the Fear & Greed index updates daily). This is sufficient for the educational purposes these tools are designed for; for real-time execution, always use your exchange's live order book.
What is impermanent loss, in plain English?
When you provide liquidity to a decentralised exchange, you deposit two assets in a fixed ratio. If the price of one asset changes significantly, you end up holding a different mix than you deposited — and if you had simply held the original amounts instead, you would often have more value. The difference is called impermanent loss. The impermanent loss calculator shows you how large this gap can be for a given price move.
