Unit Economics Calculator
Instead of already knowing your gross margin or CAC to use a single calculator, this one builds your full unit economics picture from the raw numbers on your P&L: order value, cost of goods, shipping, payment fees, acquisition cost, and repeat purchase behavior.

What This Means
At a 56.7% gross margin, this business earns $34.00 in gross profit per order. A single order does not cover the $1200 CAC on its own. Across 4 lifetime orders, LTV reaches $136 against that CAC, for an LTV:CAC ratio of 0.1:1, a sign this channel is currently losing money on every customer.
Why It Matters
Gross Margin, Breakeven CAC, LTV, and LTV:CAC all depend on each other, so calculating them one at a time in separate tools means re-entering the same numbers repeatedly and losing track of how a change in one (say, a shipping cost increase) ripples through the rest. This calculator enters the raw costs once and shows every downstream number at the same time, so the full picture updates together instead of piece by piece.
Example
A store sells at a $60 AOV, with $18 in COGS, $6 in shipping, and $2 in payment processing per order, an $1,200 CAC, and customers who place an average of 4 orders over their lifetime. Gross margin comes out to about 57%, meaning roughly $34 in gross profit per order, well short of covering a $1,200 CAC on the first sale alone. Across all 4 lifetime orders, lifetime value reaches only $136, for a 0.1:1 LTV:CAC ratio, a clear sign this channel is losing money on every customer and needs a much lower CAC or a far higher repeat rate before it's viable.
Included Calculators
Each number above also has its own standalone calculator, in case you only need one.
