Underestimating startup costs is one of the most common reasons new businesses struggle. Here's a simple way to estimate what it will really take to get started — so there are no surprises.
In This Guide
These are expenses you pay once to get started. Make a list and estimate each one — it's the easiest part to overlook, so be thorough:
These are the expenses you'll pay every month, whether or not you've made a sale yet. Estimate how many months you'll need to cover them before revenue catches up — most new businesses need several months of runway:
Things almost always cost more and take longer than expected. Add a 15–20% buffer to your total estimate so you have room to absorb surprises — equipment breaks, permits take longer, or launch slips a few weeks.
Total startup cost = one-time costs + (monthly costs × number of months before break-even) + buffer.
For example, if your one-time costs are $3,000, your monthly costs are $2,000, you expect three months before breaking even, and you add a 20% buffer: $3,000 + ($2,000 × 3) = $9,000, plus a $1,800 buffer = $10,800 to feel confident launching.
At Reed Launch Solutions, we help business owners map out real costs, set up accounting from the start, and build a budget that keeps things on track through launch and beyond.
Startup costs are any expenses you incur before your business begins generating revenue. This includes one-time costs like formation fees, licenses, equipment, and branding, plus the ongoing monthly costs you'll need to cover until you break even — rent, software, insurance, and similar expenses.
It varies widely by industry and location. A service-based business run from home might need a few thousand dollars, while a retail or food business could need $50,000 or more. The best approach is to list your one-time and monthly costs, apply the formula above, and add a buffer — that gives you a realistic number for your specific situation.
If you're leaving a job to start the business, yes — you need enough runway to cover personal living expenses until the business can pay you. Many new owners forget this and run into trouble a few months in. Include at least a few months of personal expenses in your estimate.
Because things rarely go exactly to plan. Equipment costs more, permits take longer, or revenue comes in slower than expected. A buffer gives you breathing room so a surprise doesn't derail your launch. It's one of the simplest ways to protect yourself early on.
Most new businesses should plan for at least 3–6 months of operating costs before expecting to break even. Some take longer, especially in industries with slow customer acquisition. Being conservative here is better than running out of money before you've had a chance to get going.
Yes, many service-based businesses can start with minimal upfront costs — especially if you work from home and already have the skills and tools you need. But even low-cost launches benefit from a budget. Knowing your numbers, however small, helps you make better decisions from day one.
This is general educational guidance, not financial advice. Your actual costs will vary based on your industry, location, and business model.
