How to Create a Simple Budget and Forecast for Your New Business

3 min read

A budget isn't about restricting spending. It's a plan for how the business will make and spend money, so you can make decisions before problems happen.

Budget vs. forecast

  • Budget: your plan for the year, usually set at the beginning
  • Forecast: your updated expectation based on what's actually happening

Both are useful. Start with a budget, then update your forecast quarterly.

Step 1: List your fixed costs

Costs that stay about the same each month:

  • Rent
  • Insurance
  • Software subscriptions
  • Phone and internet
  • Loan payments
  • Bookkeeping and professional fees

Don't forget annual and quarterly costs: your LLC annual report, business license renewal, insurance premiums and estimated tax payments. Divide them by 12 to see the monthly cost.

Step 2: Estimate variable costs

Costs that rise and fall with sales:

  • Materials and supplies
  • Subcontractors
  • Payment processing fees
  • Fuel
  • Sales commissions

Estimate them as a percentage of revenue, based on past jobs or industry averages.

Step 3: Estimate revenue realistically

Build revenue from the bottom up:

  • How many customers or jobs per month?
  • What's your average sale or project size?
  • How does demand change by season?

Create three scenarios: conservative, expected and optimistic. Plan your spending around the conservative case.

Step 4: Include taxes and owner pay

  • Set aside a percentage for taxes
  • Decide how much you'll pay yourself and when
  • Include Washington B&O and sales tax obligations

Step 5: Build a monthly view

Put everything in a simple 12-month spreadsheet:

JanFebMar...
Revenue
Variable costs
Gross profit
Fixed costs
Net profit
Owner pay
Tax savings

Step 6: Add a cash flow view

Add rows for when cash actually comes in and goes out, including loan principal, equipment purchases and deposits. Track your ending cash balance each month.

Step 7: Compare actual to budget monthly

When your books are closed each month, compare actual results to your budget:

  • Where are you ahead or behind?
  • Is the difference temporary or a trend?
  • What needs to change?

Know your break-even point

Break-even revenue = fixed costs ÷ gross margin percentage. If your fixed costs are $4,000 a month and your gross margin is 50%, you need $8,000 in monthly revenue to break even.

The bottom line

A simple budget gives you a target; a forecast keeps you realistic. Build both from your actual books, and review them every month.
