Break-Even Time Estimator

See how many months it takes to recover your startup investment from monthly profit.

One-time costs + first-month inventory + setup.

Net after all costs, before owner salary.

Applies to monthly profit, not revenue.

Break-even time vs break-even units

Two different concepts, often confused.

  • Break-even units — how many sales per month cover your monthly costs. A monthly measure. Answered on the Break-Even Calculator.
  • Break-even time — how many months until cumulative profit recovers your initial investment. The full-recovery measure. Answered here.

Both matter. You can be at break-even units today and still 24 months away from recovering your startup investment.

The math

  • No growth: months = investment ÷ monthly profit.
  • With growth: cumulative profit compounds each month by your growth rate. Simulate month by month until cumulative ≥ investment.
  • If it never reaches: the plan needs more capital, higher profit, or a lower startup cost.

Worked example

Startup $5,000. Current monthly profit $200. Monthly profit growth 8%.

  • Month 1: $200 (cumulative $200)
  • Month 6: $294 (cumulative ~$1,470)
  • Month 12: $466 (cumulative ~$3,600)
  • Month 16: $633 (cumulative ~$5,100) — break-even around month 16

Without growth (flat $200/mo): break-even at month 25. Growth cuts recovery time by ~35%.

What "good" break-even time looks like

  • Service businesses — often <6 months
  • Digital products / SaaS — 6–12 months
  • E-commerce (inventory) — 12–24 months
  • Hardware / physical products — 24–36 months

If your break-even time exceeds your available runway, you cannot survive to break-even without external capital. That is a hard stop, not a soft warning.

How to shorten break-even time

  1. Reduce startup cost. Every $1,000 less investment is $1,000 less to recover.
  2. Increase monthly profit. Raise price, cut costs, or increase volume.
  3. Accelerate profit growth. Compound gains matter enormously. 8% vs 3% monthly profit growth is the difference between 16 and 25 months.
  4. Launch revenue sooner. Even modest early revenue counts fully toward recovery.

What this model does not include

  • Owner salary (would extend break-even significantly)
  • Taxes
  • One-time costs paid in later months
  • Seasonality or demand cycles
  • Cashflow timing vs profit timing

Add owner salary to monthly costs if you draw one. Break-even time is very sensitive to that number.

Frequently asked questions

What is break-even time?

Break-even time is the number of months it takes for cumulative profit to equal the initial investment. After that point, every month is net profit.

What is a good break-even time?

Under 12 months is strong for most small businesses. 12–24 months is common. Over 36 months is high risk.

What if I never break even?

If monthly profit never covers the initial investment within your runway, the plan is not viable without more capital, higher price, or lower costs.

Does break-even time include taxes?

Enter profit after tax for accuracy. The model uses your net profit input.

How is it different from break-even units?

Break-even units is how many sales per month to cover monthly costs. Break-even time is how many months to recover the total startup investment.

Estimates only. This is a planning model, not a forecast. Real monthly profit is volatile and rarely grows smoothly. Not financial advice.
