For a standard POL transfer at 100 Gwei, you need approximately 0.0000021 POL (21,000 gas × 100 Gwei). Always keep a small POL buffer in your wallet.
Every action on the Polygon PoS Chain—sending POL, swapping tokens, minting NFTs, or interacting with a DeFi protocol—incurs a transaction cost. The formula is straightforward: Cost (POL) = Gas Used × Gas Price (Gwei) ÷ 10⁹. Understanding each variable helps you predict and control your spending.
Gas used is fixed by the EVM operation type. Simple POL transfers cost exactly 21,000 gas units. Token approvals cost around 46,000. Complex AMM swaps on Uniswap or QuickSwap can use 150,000–250,000 gas units depending on the number of hops and liquidity pools involved.
Gas price in Gwei is the variable you can control. Our Polygon Scan gas tracker shows the current market rate across all priority tiers. During normal conditions, setting your gas price at the Average tier (typically 100–200 Gwei) provides reliable confirmation within 2–4 seconds.
To minimize your POL transaction cost, batch multiple operations into a single transaction when possible, use protocols that employ gas-efficient contract patterns, and transact during off-peak UTC hours when competition for block space is low. The Polygon gas tracker's historical chart is your best guide for identifying low-cost windows.
Frequently Asked Questions
- What is the minimum POL needed to pay for a transaction?
- Are failed transactions refunded on Polygon?
Gas fees for failed transactions are not refunded because the network still expended computational resources. Only unused gas above the gas limit is returned.
- How does EIP-1559 affect Polygon transaction costs?
Polygon implemented EIP-1559 mechanics, introducing a base fee that is burned and a priority fee (tip) paid to validators. This makes gas prices more predictable and reduces fee volatility.
