Is this calculator really free?

Yes, no signup needed. For waste and opportunity analysis on your real campaign data, our Lite plan is $10/mo.

Where do I find my CVR and CPC?

Pull your real rates from Seller Central → Campaign Manager reports.

Where do the numbers come from?

From your inputs plus the published rates the screen names — the tool invents no rate. Anything we could not verify is NOT pre-filled: the field stays empty and the row shows “—”.

Where the CPC comes from

Split it and the tool weights the shares by their CPCs into a BLENDED CPC that the whole calculation then uses. Only SPEND is split, not CONVERSION: there is no published per-type conversion difference and inventing one would quietly bias the result. If the shares do not add to 100% nothing is computed — auto-normalising would produce a number from a split you never typed.

ⓘ Rounding: money lines are rounded to the nearest cent, and the total on screen is the sum of the lines on screen. The marketplace's own rounding can differ by a cent per line; in tiered rate cards the direction of that difference is not guaranteed.

On Amazon a daily budget is a CAP, not a spend guarantee: on any single day it can go up to 25% over (from Amazon's own Sponsored Products budget guidance), it averages across the month, and with too little impression/click supply it won't be spent at all. Setting the cap equal to the expected spend stops the campaign mid-day on roughly half the days — putting the budget at the ×1.25 line avoids that, and Amazon only bills what it spends. This doesn't say whether the budget is profitable: compare the ad cost per order against the break-even ACOS in the ACOS/PPC Profit Check.

10 September 2026 we made a correction to this calculator that changed its results: some fields accepted zero or above-100% values without warning.

The problem

Most sellers set budgets at random.

Sellers pick arbitrary numbers like '$20/day should be enough' instead of working backward from a target ad-order count — budget runs out, or gets overspent.

🎲

Arbitrary numbers

'$20/day should be enough' is a guess, not math.

⏸️

Budget runs out early

Underbudgeting stops the campaign by afternoon — half the day's traffic is lost.

📉

CVR gets ignored

Looking at CPC alone without conversion rate is misleading.
