Map one-time and recurring launch costs before spending starts. Compare lean, expected, and padded budgets. See funding gaps early and launch with better control.
Use the fields below to estimate setup needs, operating costs, funding gaps, and runway before launch.
| Cost Area | Sample Value | Type | Purpose |
|---|---|---|---|
| Equipment | 6,500 | One-time | Purchase essential startup tools. |
| Launch marketing | 2,500 | One-time | Support opening campaign reach. |
| Payroll | 6,500 | Monthly | Cover founder and staff salaries. |
| Reserve months | 6 | Planning | Build runway before steady sales. |
| Contingency percent | 12% | Planning | Absorb pricing surprises safely. |
One-Time Startup Costs = Sum of all setup expenses such as legal, equipment, branding, inventory, insurance, and launch items.
Monthly Operating Costs = Sum of recurring expenses such as rent, payroll, utilities, software, logistics, and monthly marketing.
Working Capital Reserve = Monthly Operating Costs × Reserve Months.
Base Startup Need = One-Time Startup Costs + Working Capital Reserve.
Contingency Amount = Base Startup Need × Contingency Percent.
Total Startup Cost = Base Startup Need + Contingency Amount.
Break-Even Monthly Sales = Monthly Operating Costs ÷ Gross Margin Ratio.
Runway Months = Available Funding ÷ Net Monthly Burn, where Net Monthly Burn = Monthly Operating Costs − Other Monthly Income.
Start by entering your business name, currency, and current funding. Add all one-time launch costs, including equipment, permits, and opening inventory.
Next, enter recurring monthly costs such as payroll, rent, utilities, software, and marketing. These values estimate your operating burn after launch.
Choose how many reserve months you want before revenue stabilizes. Add a contingency percentage to protect against vendor increases, delays, or missed assumptions.
Enter expected monthly revenue and gross margin percent to estimate break-even sales and monthly profit potential. Then submit the form to view your summary above.

It estimates total launch funding by combining one-time setup costs, monthly operating costs, reserve months, and a contingency buffer.
Reserve months protect the business during early volatility. They help cover payroll, rent, and essential bills before revenue becomes predictable.
Many founders use 10% to 20%. Higher-risk industries, imported equipment, or uncertain timelines may justify a larger buffer.
The calculator divides monthly operating cost by gross margin ratio. This estimates the sales needed to cover recurring expenses.
Yes, if that work would later require paid staff. Including realistic labor costs improves budgeting accuracy and investor discussions.
Yes. Replace inventory-heavy values with software, equipment, contractor, training, and marketing costs that better match your model.
Exports help you share assumptions, compare scenarios, keep records, and use the figures in cash flow planning or funding decks.
