Breakdown

ItemValue

Monthly contribution is profit per order times monthly orders minus monthly fixed costs. Break-even divides the startup cost by that contribution.

At a glance

Bars compare the startup cost with a full year of contribution. If the year bar clears the startup bar, break-even falls inside 12 months.

Net position over time

ScenarioValue

Each row is cumulative contribution minus the startup cost, assuming the same orders, profit, and fixed costs throughout. Early months are negative until the startup cost is recovered.

Formula

Months to break even = startup cost ÷ (profit per order × monthly orders − monthly fixed costs). Orders to recover the cost = startup cost ÷ profit per order. Net after N months = monthly contribution × N − startup cost.

Worked example

Startup $20,000, fixed costs $1,200 per month, profit $85 per order, 60 orders per month. Monthly contribution = $85 × 60 − $1,200 = $5,100 − $1,200 = $3,900. Months to break even = $20,000 ÷ $3,900 = 5.13 months. Orders to recover the cost = $20,000 ÷ $85 = 235.29 orders. Net after 12 months = $3,900 × 12 − $20,000 = $26,800.

Scope and limitations

Monthly contribution must be positive for any break-even to exist; if fixed costs exceed gross contribution, the model reports no break-even rather than a negative time. Sales and margins are assumptions, not guaranteed demand, and the model assumes they stay constant — seasonality, churn, price changes, and growth are not modeled. Financing costs, tax, payment timing, refunds, and the value of the founder's time are excluded unless folded into fixed costs or profit per order.

FAQ

How is break-even calculated?

Monthly contribution is profit per order times monthly orders minus monthly fixed costs; months to break even are the startup cost divided by that contribution.

What if contribution is zero or negative?

Then there is no break-even: the hustle loses money or stands still every month, and the startup cost is never recovered. Fix contribution first — more orders, higher profit per order, or lower fixed costs.

Does break-even mean profitable from then on?

It means the startup cost has been repaid. From that month onward, monthly contribution is profit before tax and before the founder's time, if neither is counted in the inputs.

Should founder time be in fixed costs?

If you want an honest answer, yes — value the hours at a reasonable rate and include them, or the break-even flatters a hustle that only works by donating unpaid labour.

Why does the order count have a fraction?

235.29 orders is the arithmetic answer; in practice it means the 236th order is the one that tips the cumulative total past the startup cost, part-way through the break-even month.

What is not included?

Financing, tax, refunds, seasonality, and demand risk. Treat the month count as a planning figure at assumed sales, and re-run it at half sales to see the downside case.
