Restaurant ROI Calculator
Capex + revenue ramp + P&L costs → 24-month cash-flow projection, payback month, annual ROI %, and stress scenarios. Answers whether the investment comes back in a timeline you can survive.
Investment
Everything you spend before the first bill is paid.
Capex + working capital. Use the capital estimator if you haven't costed this yet.
Revenue and ramp
No restaurant opens at full speed — the ramp is what delays payback.
A normal month once you are established.
Months to reach steady state.
Share of steady revenue you expect in month 1.
Monthly costs
Enter the bottom line you already know, or build it up from P&L lines.
After rent, salaries, food cost, aggregator commission, and owner draw.
Your payback
LiveCumulative net profit vs investment
Teal marks the months after your investment is fully recovered.

Stress scenarios
How payback and first-year return shift when assumptions change.
| Scenario | Payback | Year-1 ROI | Year-1 net |
|---|---|---|---|
| Base case | Month 22 | 53.2% | ₹18,63,000 |
| Revenue −15% | 24+ mo | 18.1% | ₹6,33,420 |
| Net profit −25% | 24+ mo | 39.9% | ₹13,97,250 |
| Ramp +2 months | Month 22 | 50.4% | ₹17,64,000 |
Capex is only half the question
The capital estimator tells you how much you will spend. The break-even calculator tells you the revenue line. This tool tells you whether that spend comes back in a timeline you can survive — accounting for the 4–8 month ramp that no new restaurant avoids.
The model runs a 24-month cash-flow projection: during the ramp period revenue climbs linearly from your opening-month percentage to steady state, while fixed costs stay constant from day one. The payback month is the first month where cumulative net profit equals or exceeds your total investment. Stress scenarios re-run this projection with altered assumptions to show how fragile the model is.
Restaurant ROI and payback formulas
Payback (months) ≈ Investment ÷ average monthly net profit (after ramp). Annual ROI % ≈ (12 × steady-state monthly net) ÷ Investment × 100. Always include working capital in Investment — year-one failures are usually float failures.
Pair it with the profit calculator, break-even calculator, cost-to-open estimator, and viability score before you commit.
