Which Cheap iPhone Should You Buy? (Quick Guide)

If you’re not sure which model is right for you, here’s a simple guide based on what most buyers want when searching for cheap iPhones:

• Best cheap iPhone overall: Refurbished iPhone 13 – excellent performance at a much lower price than newer models, and a great balance of value and longevity.
• Best “newer model” cheap deal: Refurbished iPhone 14 – ideal if you want a newer-feeling iPhone while still paying less than retail.
• Best cheap 5G iPhone: Refurbished iPhone 12 – a strong upgrade if you want modern design and 5G without a big price jump.
• Best budget iPhone: Refurbished iPhone 11 – perfect for everyday use, teens, students, or anyone wanting the lowest-cost iPhone option.

Condition Grades Explained (How to Get the Cheapest iPhone)

All grades are fully functional and tested — the difference is mainly cosmetic condition. Choosing the right grade is one of the easiest ways to get a cheaper iPhone at the best value.

• Like New: Excellent cosmetic condition with minimal to no visible marks (best-looking).
• Very Good: Light signs of use, such as small marks or minor wear (popular balance of price/condition).
• Good: Noticeable cosmetic wear, but fully tested and working as intended (usually the cheapest option).

If price is your priority, choose Good condition for the best deal. If you want a bargain that still looks great, Very Good is often the sweet spot.
