FBA Calculator by 3PLGuys

什麼是 FBA Calculator by 3PLGuys？

Most FBA calculators are outdated, gated behind email walls, or built to upsell you software. Ours is different: current 2026 Amazon fee data (fulfillment, storage, referral, inbound placement, low-inventory fees), instant results with real profit and margin breakdowns, and zero signup no email gate, no trial, no catch. It's built by 3PLGuys, an Amazon SPN-certified prep center that handles FBA inventory every day, so the fee logic reflects what sellers actually pay, not a simplified estimate.
