Coupon Savings Calculator
Calculate savings from stacking multiple percentage and dollar-off coupons. Verify minimum spend qualification thresholds and net savings.
Multi-Coupon Stacking Formula
Subtotal = (Cart - Σ Percent Coupons Sequentially) - Σ Dollar Coupons; Net Savings % = (Total Deductions / Original Cart) × 100- Eligibility Gate: Cart subtotal must meet or exceed the retailer’s minimum order threshold (e.g., $75) before coupons activate.
- Sequential Stacking: Percentage vouchers apply sequentially to diminish the balance before fixed dollar coupons are subtracted.

Frequently Asked Questions
What happens if a coupon brings my total below the free shipping threshold?
Many retailers assess free shipping thresholds on the post-coupon subtotal. If a $10 coupon drops your cart from $52 to $42 on a $50 free shipping threshold, you may incur an $8 shipping fee, negating the coupon value.
