Estimate Prime Day or major sale event revenue. Enter base daily revenue, expected lift multiplier, and duration to forecast total revenue and inventory.
Amazon Prime Day and similar mega-sale events (Target Circle Week, Walmart's competing sales) create a halo effect across all e-commerce channels. Even brands not selling on Amazon often see 1.5–3× lifts during Prime Day as consumer shopping behavior surges across the board.
This calculator helps you estimate revenue for Prime Day or any major multi-day sale event. Enter your normal daily revenue, the expected lift multiplier (anywhere from 2× for moderate participation to 10× for aggressive Lightning Deals), the sale duration, and your average order value. The tool outputs total projected revenue, estimated orders, and the inventory you'll need.
Use this 4–6 weeks before Prime Day to ensure you have adequate inventory, fulfillment capacity, and ad budget allocated. Whether you are a beginner or experienced professional, this free online tool provides instant, reliable results without manual computation. By automating the calculation, you save time and reduce the risk of costly errors in your planning and decision-making process.
Prime Day can generate a month's worth of revenue in 48 hours, but only if you're prepared. This estimator ensures you have the inventory, ad budget, and fulfillment capacity to capture the surge without stockouts or late shipments. Having a precise figure at your fingertips empowers better planning and more confident decisions.
Event Revenue = Base Daily Revenue × Lift Multiplier × Duration Days Estimated Orders = Event Revenue / AOV Inventory Needed = Estimated Orders × 1.2 (safety buffer) Gross Profit = Event Revenue × (1 − COGS %)
Result: Event Revenue: $40,000 | Orders: 889 | Inventory Needed: ~1,067 units
Event revenue = $5,000 × 4 × 2 = $40,000. Estimated orders = $40,000 / $45 = 889. With 20% safety buffer, inventory needed = 889 × 1.2 = 1,067 units. Gross profit = $40,000 × (1 − 0.35) = $26,000.
Week 8–6 before: submit deal applications, order inventory. Week 4: ship inventory to FBA warehouses. Week 2: finalize ad creatives, set up PPC campaigns, prepare email/SMS sequences. Week 1: activate early-access deals for loyal customers. Day of: monitor hourly and adjust bids, budgets, and pricing in real time.
Your lift depends on three factors: deal depth (deeper discounts → higher lift), deal visibility (Lightning Deal > Best Deal > Coupon > no deal), and category demand (electronics and home goods see higher lifts than niche categories). Start conservative (2–3×) if this is your first Prime Day.
Prime Day drives shopping intent across all channels. Run competing promotions on your DTC site, send dedicated email and SMS campaigns, and increase social ad spend during Prime Day week. Many brands report their DTC channels see 30–50% revenue lifts during Prime Day without any marketplace participation.
The lift varies dramatically by category and deal type. Brands with Lightning Deals see 5–10× normal sales. Brands running standard promotions see 2–4×. Even sellers with no deal at all often see a 1.3–2× lift from increased marketplace traffic.
Prime Day has expanded from 36 hours to a full 48-hour event (2 days). Some years Amazon extends it with early access deals starting 12–24 hours before the official start. Plan for 2–3 days of elevated demand.
Yes. Prime Day creates a consumer shopping event that spills over to all channels. DTC sites, Shopify stores, and other marketplaces see 20–50% traffic lifts during Prime Day week. Run competing promotions on your own channels to capture this demand.
Stock 120–150% of your projected unit demand for top sellers. Factor in the 2–3 week post-Prime Day period where demand remains 10–20% elevated. For Amazon FBA sellers, ensure inventory arrives at fulfillment centers 3–4 weeks before Prime Day.
Lightning Deals generate the highest volume but require deep discounts (20–40% off). Best Deals (badge deals) offer strong visibility with moderate discounts. Coupons are the easiest to set up and still boost conversion. The best strategy combines deal types across your catalog.
Calculate all-in costs: product COGS, Amazon referral fees, FBA fees, deal fees, PPC spend, and any discounts. Subtract from total revenue to get net profit. Also track 30/60/90-day repeat purchase rates from Prime Day buyers to capture full customer value.
