10% Off vs Free Shipping — Which Is Better?

The Breakeven Formula: When Does 10% Off Beat Free Shipping?

The math is straightforward. With a % off coupon, you pay the discounted price plus shipping. With free shipping, you pay full price but no shipping. The discount wins when:

Below $80, free shipping saves more. Above $80, the 10% discount saves more. At exactly $80, they're identical.

When Each Option Wins

Small orders ($20–$50): Free shipping almost always wins. A 10% discount on $30 saves $3, but shipping typically costs $5–10.

Medium orders ($50–$100): It depends on the exact shipping cost. At $75 with $7 shipping, 10% off saves $7.50 — the discount barely edges out free shipping.

Large orders ($100+): The percentage discount usually wins. At $200, 10% off saves $20 — far more than typical $8–12 shipping costs.

Real-World Scenarios

Amazon: Free shipping threshold is typically $35. If your cart is $40 with a 10% coupon, the discount saves $4 while free shipping would save $5–7. Free shipping wins.

Clothing stores: Shipping is often $5–8. A 10% discount on a $60 dress saves $6. If shipping is $7, free shipping wins by $1. On a $100 order, the 10% ($10) beats shipping ($7) by $3.

Heavy/bulky items: Shipping can be $15–30 for furniture or equipment. Even a 10% discount needs a $150–$300 cart to beat free shipping on these items.
