In short

MMC's free tools are calculators and a glossary that help a D2C brand work out what a customer can cost, where the funnel leaks, and how long profit takes. They cover unit economics, break-even ROAS, funnel ROAS, LTV:CAC and CAC runway. There is no email wall or sign-up, and your own numbers decide the answer.

D2C calculators

Start from the decision, not the tool.

Each calculator is grouped by the question it helps you answer.

Can I afford to pay for a customer?

Cost and profit
01 · Unit economics

Unit economics calculator

What you may be doing instead

Looking at revenue per order and not at what is left after COGS, fulfilment, RTO and CAC.

Use this when

You want to know whether one order really contributes, and the volume you need to break even.

Open the calculator
02 · Break-even ROAS

Break-even ROAS calculator

What you may be doing instead

Chasing a ROAS number you heard somewhere, instead of the one your own cost sheet gives.

Use this when

You are setting or judging a ROAS target and want the exact break-even, and the one that hits your target margin.

Open the calculator
03 · LTV:CAC

LTV:CAC calculator

What you may be doing instead

Judging a customer by the first order alone.

Use this when

You plan to keep customers and want to see the month your acquisition cost is paid back.

Open the calculator

Where does my ad funnel leak?

Efficiency
04 · Funnel ROAS

Funnel ROAS calculator

What you may be doing instead

Raising spend to fix efficiency, when spend buys volume and not efficiency.

Use this when

ROAS is low and you want to see which step between an impression and a paid order is leaking.

Open the calculator

How long until it works, and how far does it go?

Time and growth
05 · CAC runway

CAC runway calculator

What you may be doing instead

Expecting a new brand to hit break-even CAC on day one.

Use this when

You are launching or relaunching and need to know how long it takes to turn, and how much cash it burns.

Open the calculator
06 · Growth trajectory

Growth trajectory calculator

What you may be doing instead

Holding a year-one month-on-month growth rate for five years.

Use this when

You want to see where today's run rate actually gets you.

Open the calculator

What does that term mean?

Plain English
07 · Glossary

D2C Marketing Glossary

What you may be doing instead

Nodding along to ROAS, RTO or contribution margin without being sure what they mean.

Use this when

A term in a calculator, a report or an ad account is unclear.

Open the glossary

Calculator screens shown here use example numbers, not real results.

Reading the results

A number is not a verdict.

Nothing here judges your brand. It shows the shape of the problem and the order worth fixing it in.

Use your own numbers

Start from your cost sheet and your ad account, not from a figure you heard elsewhere. Your break-even is specific to you.

Change one input at a time

Move one number, see what changes, then move the next. That shows which lever matters most.

Count returns and fees

RTO, shipping and gateway fees quietly reduce what an order leaves behind. Put them in before you trust a result.

Which order to run them in

Start with unit economics: if one order does not contribute, nothing downstream matters. Funnel ROAS then shows where efficiency is lost, break-even ROAS shows the efficiency you need, and LTV:CAC shows how patient you can afford to be. CAC runway answers how long a new brand burns before it turns, and growth trajectory projects the margin forward.

Common questions

What people ask about the tools.

Are the tools free?

Yes. There is no email wall and no gated download. You put your numbers in and see the answer.

Which calculator should I start with?

Start with unit economics. If one order does not contribute, nothing downstream matters. Then use break-even ROAS for the efficiency you need and LTV:CAC for how patient you can be.

Is the result a verdict on my brand?

No. A number shows the shape of the problem and the order worth fixing it in. It does not judge your brand.

Can MMC run these numbers with me?

We can. Book a strategy call and bring the question that is stuck.
