Every promo costs margin. Know how much before you sign.
Ringo models every Amazon Vendor deal per ASIN, across co-op, MDF, freight and VAT, then gives a clear verdict.
Running a calculation sends none of your deal numbers to us. How we handle your data
The spreadsheet that costs you money every quarter.
Vendor Central tells you what happened. Ringo Analytics tells you what will happen, before you sign.
What the dashboard shows
Promo vs. normal weeksLooks like a clear win worth funding.
What each unit actually earns
Example dealRingo viewYou earn €0.84 less per unit.The uplift has to pay it back.
From inputs to fund or walk in minutes.
Enter the deal
Invoice price, discount, co-op, MDF, accruals, freight and expected volume uplift. 3 ASINs per deal on the free calculator, up to 100 on Premium.
The engine runs the maths
Three readings: the contribution the deal adds against doing nothing and the margin it costs over the month, per ASIN and across the portfolio, and whether your forecast is plausible for the discount. Plus the uplift you need to break even.
Fund or walk
The worst of the three readings is the verdict, with Bear/Base/Bull sensitivity and the exact terms that turn a bad deal good.

Ringo Analytics runs the Math Constitution: the same contribution, PPM, break-even uplift and basis-point logic your finance team would apply by hand, but consistently and across every ASIN. Every output traces back to the inputs you entered.
First, profit: Fund if the deal earns more than doing nothing even at half your forecast uplift, or loses under 15% of its gain there; Warning if it only makes money at the full forecast; Do not fund if it loses money; Critical if it sells below cost, on an ASIN or across the deal. Second, margin: the deal is swapped into a normal month and the margin it costs over that month is read against a ladder, by default Fund down to -200 bps, Warning to -400, Do not fund to -600 and Critical beyond. Third, plausibility: if your forecast sits above the typical uplift for this discount and the deal loses money at the top of that band, it reads Warning. The verdict is the worst of the three readings, except that a deal which makes money reads Warning at worst: red always means a loss or selling below cost.
Not yet. Today you enter deal terms manually, from invoice price and discount through co-op, MDF, accruals and freight. A Vendor Central import is on the roadmap for pilot brands.
Running a simulation never sends your numbers anywhere. The engine executes in your browser, so deal inputs are not transmitted to us, signed in or not. Signing in stores your email address; a deal or library product is stored only when you save it. Product analytics runs only if you accept it, on EU infrastructure, and is never linked to your account. Share links carry the deal encoded inside the link itself, so forwarding a result still doesn't send it to us.
3 ASINs per deal on the free calculator, up to 100 on Premium, with per-market VAT, co-op and MDF, accrual leakage, freight and payment-term effects. Each deal runs Bear / Base / Bull volume scenarios so you see the full sensitivity band.
It shows Amazon's side of a deal: the funding Amazon will ask you to pay, ASIN by ASIN, and what the deal does to Amazon's margin. It is free for up to 3 ASINs per analysis (20 on Plus, 50 on Pro, 100 on Premium), and your numbers stay in your browser tab.
The calculator is free to use for deals of up to 3 ASINs. Paid plans are Plus at €29.99 per month, Pro at €69.99 per month and Premium at €149.99 per month. Those figures include VAT: they are the total charged, not a pre-tax price. New accounts get a 7-day Pro trial with no payment card required.
Spain, Italy, France, Germany, the Netherlands, Belgium and the UK at launch, with the correct VAT and cost treatment for each. More EU markets follow based on pilot demand.
