Two New Calculators Now Live: Tax Estimator & Token Risk Analyser
CrypCal launches a Capital Gains Tax calculator for UK, US, Australia and EU, plus an updated Token Price Analyser with smarter risk scoring for major stablecoins and blue-chip tokens.
Two New Calculators Now Live: Tax Estimator & Token Risk Analyser
CrypCal has two new tools live today — a Capital Gains Tax estimator covering UK, US, Australia and EU jurisdictions, and an updated Token Price Analyser with smarter risk scoring that correctly handles major stablecoins and blue-chip tokens. Both tools are completely free, require no signup, and store no data on our servers.
The Tax Calculator: Estimate Your Crypto Capital Gains
The Tax Calculator gives you a deterministic CGT estimate based on the numbers you enter. It is designed to help you quickly understand your potential tax liability before speaking to an accountant or filing your return. The calculation is fully transparent — same inputs always produce the same result.
To use the calculator, select your jurisdiction and tax rate band, then enter your buy price, sell price and quantity. The calculator works out your gross gain, taxable gain after the applicable annual allowance, estimated tax liability, and effective tax rate.
Four jurisdictions are currently supported with their specific tax rules built in:
United Kingdom: The calculator applies the £3,000 annual CGT exempt amount for the 2024/25 tax year, with basic rate taxpayers taxed at 18% and higher rate taxpayers at 24% on gains above the allowance. The UK tax year runs from 6 April to 5 April.
United States: Long-term capital gains rates of 15% for most taxpayers and 20% for higher earners apply to assets held over one year. No annual allowance is applied. Short-term gains are taxed as ordinary income.
Australia: The 50% CGT discount applies automatically when the asset has been held for more than 12 months. The remaining gain is added to your income and taxed at your marginal rate. No separate annual allowance is applied in the calculator.
European Union: A general 20% estimate is used as a baseline, with the understanding that rates vary significantly by member state. This provides a rough reference point rather than a precise calculation.
Important: These are generic educational estimates based on simplified tax rules. They are not tax advice. Tax law is complex and depends on your full financial situation including other income, gains, losses and deductions. Always consult a qualified tax professional for advice specific to your situation.
Token Price Analyser: Smarter Risk Scoring
The Token Price Analyser fetches live on-chain data from public APIs and runs a deterministic, point-based risk model. Paste any Ethereum contract address and you get an instant snapshot of price, total DEX liquidity, fully diluted valuation, and 24-hour trading volume, plus a risk context score with plain-English explanations.
What changed in this update
The risk scoring now correctly handles major stablecoins and blue-chip tokens. USDC, USDT, DAI, WETH and WBTC previously scored Medium due to low DEX liquidity relative to their fully diluted valuation. While this is technically correct from an on-chain perspective, it was misleading — the vast majority of trading volume for these tokens occurs on centralised exchanges, not DEXs.
These tokens now receive a Low risk context score with an explanatory note that clarifies the scoring rationale. This makes the tool far more useful for analysing the tokens that most traders actually encounter.
How the risk score works
The model is fully deterministic — same inputs always produce the same output. It scores three independent signals:
- Liquidity depth — the absolute USD value of on-chain liquidity available in DEX pools
- Liquidity vs FDV ratio — how much on-chain liquidity backs the token's fully diluted valuation
- Volume vs liquidity ratio — whether trading activity is consistent with normal market behaviour
Each signal is scored against predefined thresholds, and the three scores combine to produce a final context level of Low, Medium or High. Every score includes an explanation of which signals were triggered and why.
What Is Coming Next
We are continuing to expand the calculator suite with several tools in active development:
Portfolio Tracker: Manual entry with localStorage persistence. No wallet connection, no data stored on servers. Track your holdings across multiple wallets and exchanges in one place.
Impermanent Loss Calculator: For DeFi liquidity providers who need to understand the potential cost of providing liquidity to automated market maker pools.
Stablecoin Peg Tracker: Monitor de-peg events across major stablecoins including USDT, USDC, DAI and others. Historical data and real-time alerts for significant deviations.
L1 vs L2 Fee Comparison: See real-time transaction costs across Ethereum, Arbitrum, Base, Optimism and other major networks. Compare costs before choosing where to transact.
CrypCal Stays Free
Every tool on CrypCal is completely free, requires no account, and stores nothing on our servers. Calculator inputs stay in your browser using local state — they disappear when you close the tab. We do not connect to wallets, we do not give financial advice, and we do not track you across the web. Our mission remains simple: give you the maths, clearly, so you can make your own informed decisions.
CrypCal is a global educational platform. All outputs are estimates based on public data. This is not financial, tax or legal advice. Consult a licensed professional before making decisions.
