How This Calculator Works
Calculation methodology and assumptions
Total startup cost = One-time costs + Operating reserve + Contingency (15%). Funding needed is the same gross total, before savings or financing. Monthly overhead plus marketing allocation = monthly overhead + marketing budget / 12; its annual allowance is not break-even revenue because sales margins, variable costs and taxes are not modeled. One-time costs include equipment, inventory, legal fees, and marketing. Operating reserve = monthly overhead × desired runway months. The 15% contingency is this worksheet’s illustrative planning assumption applied to one-time costs plus the reserve, not an SBA recommendation. Replace the inputs with actual quotes; this is a funding worksheet, not a forecast of business success.
Build a launch funding worksheet
- 1
Collect one-time quotes
Enter equipment and technology, opening inventory, legal and licensing fees, and the launch marketing budget. Use current written quotes; defaults are an illustration.
- 2
Choose overhead and reserve months
Enter the monthly overhead you expect to pay even if sales are delayed, then select how many months to reserve. This multiplies the two inputs; it does not forecast customer revenue.
- 3
Inspect the fixed 15% assumption
The worksheet adds 15% of one-time costs plus the operating reserve. This is our illustrative contingency assumption, not an SBA recommendation or a measured industry average.
- 4
Complete your funding plan
The gross funding result does not subtract savings, loans or investor funds. Add omitted payroll, deposits, insurance, debt service, taxes and owner living expenses to your own cash-flow plan.
Example: reconcile the default funding total
Equipment $15,000.00, inventory $5,000.00, legal/licensing $3,000.00 and launch marketing $5,000.00. These are chosen example inputs, not price benchmarks.
One-time costs total $28,000.00. Monthly overhead $5,000.00 × 6 reserve months = $30,000.00. The 15% planning allowance on their combined total adds $8,700.00.
Result: Gross launch funding: $66,700.00. The separate monthly overhead plus marketing allocation is $5,417.00 after rounding; its annual allowance is $65,000.00. Neither is break-even revenue: the model has no sales volume, variable cost, margin or tax input.
What the worksheet covers
One-time purchases
The four opening-cost inputs are added together. They do not estimate depreciation deductions or decide which expenditures can be deducted for tax purposes.
Operating reserve
Each additional month increases the reserve by your overhead input, and also increases the fixed contingency applied to that reserve.
Costs outside the fields
Staffing, variable inventory replenishment, financing and revenue timing can change the cash requirement. Use a separate month-by-month cash-flow forecast before making commitments.
Stress-test your own assumptions
- Save a low, expected and high quote for each large purchase. Re-run the same worksheet with each set instead of treating the default as an industry norm.
- A reserve is money set aside. Actual runway depends on the dates cash comes in and goes out; a six-month reserve input is not a promise of six months of survival.
- The marketing budget is counted once in launch funding. The monthly allocation simply spreads that same budget over 12 months for comparison; do not add it to launch funding again.
- The SBA startup-cost guidance provides a planning framework. It is not used here as evidence for an average startup cost, contingency percentage, failure rate or required runway.

Our editorial standardsFrequently Asked Questions
How much does it cost to start a business?
Build your own budget from equipment, inventory, legal and licensing fees, marketing, and monthly overhead. The defaults are an illustration, not an industry average or a quote. Include any omitted deposits, payroll, insurance, taxes or financing costs in your own worksheet.
How many months of runway should I have?
Choose reserve months using your own launch schedule and cash-flow scenarios. This calculator multiplies monthly overhead by that selection; it does not predict how long cash will last after variable sales, collections, debt service or changing expenses.
