🧮 Fee Calculator
🧮 What does one copy round-trip (buy + sell) really cost?
On-chain trading fees are mostly FIXED per transaction (network priority fees + account rent), not a percentage. That means small positions get eaten alive: the same ~0.005 SOL that is 3% of a 0.15 SOL trade is 50% of a 0.01 SOL trade. This calculator shows your real breakeven.
| Size (SOL) | Total fee | Fee % of size | Breakeven gross |

Defaults reflect typical fast-lane Solana costs: priority fees + tip ≈ 0.004–0.006 SOL per round trip, plus ~1% service fee if your route uses a transaction builder. Token-account rent (~0.002 SOL) is a refundable deposit — reclaim it with our Wallet Health scanner.
