What belongs in a startup budget?

Add the payments required to open, then fund the early cash shortfall. Keep the two parts visible.

The direct answer

Capital to arrange = payments before opening + required cash reserve.

A quote for equipment is not a complete opening budget. Neither is a multiple of monthly expenses. Start with the operating format and place each payment on a timeline.

The checklist and formulas are general planning guidance. Every amount in the linked examples is synthetic.

1. List what must be paid before opening

Build the list around actual commitments. Keep refundable deposits, equipment and opening stock separate because their later accounting treatment differs.

The opening payment list
Payment groupWhat to recordCommon omission
Premises and setupFit-out, installation, signage and pre-opening workMaking the site usable, not only obtaining the lease
Equipment and systemsPurchase, delivery, installation and setupA quote may exclude shipping or commissioning
Deposits and prepaid itemsLease and utility deposits; advance premiumsA refundable deposit still consumes cash
Opening stockInitial inventory and suppliesAvoid subtracting this cash payment twice
PreparationRecruitment, training, launch and local requirementsPaid preparation happens before the first sale

2. Model the cash gap after opening

Estimate receipts and payments month by month. A business that reaches a healthy mature month can still run out of cash on the way there. Show a realistic ramp, required paid labor and the timing of each payment.

Set a minimum cash balance, then add the deepest cumulative cash deficit. If cash remains negative every mature month, a larger reserve only postpones the problem.

Reserve = minimum cash balance + maximum cumulative operating cash deficit

3. Check the budget before using it

  • Every payment appears once.
  • The owner’s required work is paid or explicitly valued.
  • Taxes, debt payments and working capital are included where applicable, or the exclusion is visible.
  • Deposits and stock are kept separate from operating expenses.
  • The cash reserve has a stated horizon and minimum balance.
  • Quotes, observed periods and location are recorded.

This on-page checklist is temporary and is not submitted.

4. Trace a worked example

The Restaurant × Texas prototype shows opening payments, a separate reserve, monthly cash flow and a payback calculation using one set of assumptions. Its numbers illustrate the method; they are not local evidence.

Method and next step

The SBA planning resource provides a starting point for identifying opening expenses and recurring costs. Our reserve calculation then follows the stated monthly cash timeline.

Now test the sales threshold.

A funded opening still needs an operating model that works.
