POS system pricing is notoriously confusing in 2026. Vendors advertise “$0/month” while hiding processing fees, hardware costs, and mandatory add-ons. This guide reveals the true monthly cost of the 5 most popular POS systems so you can budget accurately before you commit.

The 4 Cost Components Every Business Must Calculate

  1. Software fee: Monthly subscription for the POS software
  2. Hardware cost: One-time purchase (or amortized monthly)
  3. Processing fees: Percentage of every card transaction
  4. Add-ons: Loyalty, payroll, online ordering, marketing tools

Most POS comparison articles only show the software fee. That’s like comparing car prices without mentioning fuel, insurance, or maintenance.

Hidden Fees to Watch Out For

  • PCI compliance fees: $5-$120/year (charged by some processors)
  • Chargeback fees: $15-$25 per dispute
  • Early termination fees: $0-$500+ if you cancel a contract
  • Hardware lease buyout: Often more expensive than buying outright
  • Statement fees: $10-$25/month from some legacy processors
  • Gateway fees: $10-$25/month for some online payment gateways
  • Batch processing fees: $0.10-$0.30 per batch with some processors

How to Calculate Your True Monthly POS Cost

Use this formula: (Monthly Sales x Processing Rate) + Software Fee + (Hardware Cost / 36) + Add-on Fees = True Monthly Cost

Example for a retail store doing $30,000/month on Square Plus:

  • Processing: $30,000 x 2.6% + (150 transactions x $0.10) = $780 + $15 = $795
  • Software: $60
  • Hardware (Square Terminal $299 / 36 months): $8
  • Loyalty add-on: $45
  • Total: ~$908/month
