Polygon Profit Calculator
Polygon began as a proof-of-stake sidechain scaling Ethereum and has become a family of scaling technologies including zkEVM rollups. Its token has been through a migration from MATIC to POL.
How This Asset Works
- Role: Ethereum scaling, not an independent layer 1
- Fees: cents rather than dollars
- Finality: fast on the PoS chain; inherits Ethereum security on the rollups
- Staking: delegate to validators for yield
- Token migration: MATIC to POL, which holders must action
What You Can Calculate

The Risk Specific to This Asset
Polygon competes with Arbitrum, Optimism, Base and Ethereum's own roadmap, and the layer-2 field is unusually crowded. The PoS chain is a sidechain with its own validator set rather than a rollup, so it does not inherit Ethereum's security in the way the name suggests — a distinction worth understanding before sizing a position.
Risks Common to Every Crypto Asset
- Custody: losing a private key loses the asset permanently, with no recovery process
- Regulation: treatment varies by jurisdiction and changes with little notice
- Counterparty: an exchange balance is a claim on the exchange, not an asset you hold
- Volatility: 50%+ drawdowns are ordinary rather than exceptional in this asset class
Costs That Turn a Gain Into a Loss
| Cost | Typical | When it applies |
|---|---|---|
| Exchange fee | 0.1–1.5% | Both on buy and on sell |
| Spread | 0.05–1% | The gap between quote and fill |
| Network fee | $0.01–$50 | Per on-chain transaction |
| Withdrawal fee | Fixed per asset | Moving off the exchange |
| Conversion | 0.5–2% | Fiat in and out |
Volatility Is Not Symmetric
| Drawdown | Gain needed to recover |
|---|---|
| −10% | +11% |
| −25% | +33% |
| −50% | +100% |
| −75% | +300% |
| −90% | +900% |
Custody
"Not your keys, not your coins" is not a slogan — Mt. Gox, QuadrigaCX, Celsius and FTX all lost customer assets held on their platforms.
| Where | Control | Risk |
|---|---|---|
| Exchange | Theirs | Insolvency, freeze, hack |
| Hot wallet | Yours | Malware, phishing |
| Hardware wallet | Yours | Physical loss, seed exposure |
| Multisig | Shared | Complexity |
Tax Follows Every Disposal
In the US the IRS treats crypto as property, so selling, swapping one token for another and spending it are all taxable events, whether or not dollars moved. Cost basis must be tracked per lot, per wallet. Without records the default assumption is a zero basis, which makes the entire proceeds taxable.
