Formula used

  • Original subtotal: unit_price × quantity
  • Tier selection: choose the highest min_qty where quantity ≥ min_qty
  • Bulk discount (percent): subtotal × (discount% ÷ 100)
  • Bulk discount (per unit): quantity × discount_amount
  • Coupon discount: calculated on the chosen base (before or after bulk)
  • Net products subtotal: subtotal − bulk_discount − coupon_discount
  • Payment fee: fee_base × (fee% ÷ 100)
  • Tax: taxable_base × (tax% ÷ 100)
  • Grand total: net_products + shipping + handling + fee + tax
  • Effective unit price: net_products ÷ quantity

The discount cap limits the total bulk discount. The unit price floor prevents aggressive discounts that undercut a target minimum.

Tiered pricing lifts order value with clear targets

Bulk discounts perform best when the next quantity goal is obvious. Many catalogs use three tiers such as 10+, 50+, and 100+ units. The first tier reduces hesitation, while higher tiers encourage add‑ons. After each change, review average order value, conversion rate, and gross margin per order so the offer grows revenue without silently weakening profitability. Use cohort reporting for better comparisons.

Choosing breakpoints from demand and operations data

Place tier minimums where packing effort and inventory risk remain predictable. If shipping switches from parcel to freight at a certain carton count, set a tier just below that point. For seasonal items, tighten tiers and reduce the step size to avoid early stockouts. A common pattern is 3–7 percentage points between tiers, adjusted by margin.

Percent and per‑unit discounts influence buyer perception

Percent discounts scale with price, keeping premium variants aligned. Per‑unit discounts feel concrete for repeat buyers and fit wholesale lists. Use the calculator to compare effective unit price at identical quantities. When product prices vary widely, percent tiers keep rules consistent; when pricing is uniform, per‑unit tiers simplify quoting and reduce rounding disputes.

Model checkout reality by including fees and tax rules

A discount can look safe until taxes, payment fees, and charges are included. Add shipping and handling to view the true grand total across quantities. Processor fees that include a percentage plus a fixed component become less painful on larger orders, improving margin. Toggle whether shipping is taxable to match your local checkout policy.

Protect margin with caps, floors, and cost visibility

Use a discount cap to stop unusually large carts from receiving outsized reductions. A unit price floor helps you stay above a target minimum or cost threshold. Enter cost per unit and fulfillment cost to estimate product profit quickly. Once tiers are validated, export results and share them with sales and finance for consistent pricing decisions.

FAQs

What is the difference between tiered and flat discounts?

Tiered discounts change with quantity breaks, so bigger orders unlock stronger pricing. Flat discounts apply the same percent, per‑unit, or order amount regardless of quantity, making them simpler but less targeted.

Should I apply coupons before or after bulk pricing?

Apply coupons after bulk pricing when you want tiers to drive volume first. Apply before bulk pricing when coupons are part of the base offer. Test both, because the order changes net subtotal and margin.

How do I set a discount cap?

Use the cap to limit the maximum bulk discount value on a single order. It prevents extreme savings on unusually large quantities and keeps total discount spend within a planned budget.

What does “unit price floor” protect?

A floor stops discounts from pushing the effective unit price below a minimum. It helps protect margins, minimum advertised pricing, or cost‑based guardrails when customers combine high quantities with aggressive promotions.

Why include payment fees in the calculation?

Payment processors often charge a percentage and sometimes a fixed fee. Including fees shows how discounting affects net revenue, especially on small orders where fixed fees can materially reduce margin.

Can I use the export files for approvals?

Yes. Download CSV for spreadsheets and review workflows, or PDF for sharing a clean summary. Exports help align sales, finance, and operations on the same pricing assumptions.
