Polygon Gas Fee Calculator
$40.00
Calculate your Polygon transaction cost before you send. Input gas price in Gwei and gas limit to see the total fee in both POL and USD.
The Polygon gas fee calculator is an essential tool for Polygon users. Before submitting, knowing the expected fee prevents overpayment.
How to calculate Polygon gas fees:
- Check current base fee plus priority fee in Gwei from a live tracker
- Identify gas limit for your transaction type: simple transfer = 21,000 gas; ERC-20 = 65,000 gas; DEX swap = 150,000 to 300,000 gas
- Multiply: Gas Limit x Gas Price (Gwei) divided by 1,000,000,000 = POL amount
- Multiply POL x current POL/USD price = USD cost
Example: Gas price 80 Gwei, DEX swap with 200,000 gas: 200,000 x 80 divided by 1,000,000,000 = 0.016 POL. At $0.50/POL = $0.008 USD.
MetaMask frequently overestimates priority fees on Polygon by up to 10x. Always cross-check with a live gas tracker before accepting defaults.

"The calculation guide helped me understand exactly what I was paying. I now set manual gas prices in MetaMask and save on each transaction."
