You may have saved enough for equipment, permits, and rent. But what about the months before customers bring in enough money to pay the bills? Here’s how to find out what you really need.
You’ve been saving to open a business. Maybe it’s a bakery, a beauty salon, or a small neighborhood shop.
You’ve priced the equipment. You know what the rent will be. You’ve looked into permits and licenses.
And finally, it seems like you have enough money to get started.
But there’s another question worth answering before you sign a lease or spend your savings.
What happens if the business opens and customers don’t come as quickly as you hoped?
The rent still has to be paid. You may need more supplies. If you have employees, they need their paychecks. And at home, the grocery bill, car payment, and other family expenses haven’t stopped.
For anyone planning to open a small business in California, having enough money to get started is only part of the calculation.
You also need a plan for keeping the business running while sales are still growing.
The Money You Need Before Opening
The U.S. Small Business Administration recommends calculating startup costs before opening a business.
But don’t stop at the equipment, permits, and other purchases you need to make before opening day.
Think about three different amounts.
First, what will it cost to open?
This includes equipment, initial inventory, deposits, licenses, permits, insurance, and any work needed to prepare your space.
Second, how much money will the business need while sales are growing?
Even after opening, you may not bring in enough money to cover rent, utilities, supplies, payroll, and other bills. You need cash to cover the difference.
Third, how will you pay your household expenses?
If you’re leaving a job or cutting back your hours, will you still have enough for housing, groceries, transportation, health insurance, and other family needs?
You’ll also want money set aside for unexpected expenses.
SCORE, a nonprofit organization that helps small-business owners, includes both money for ongoing operations and an emergency cushion in its startup-expense worksheet.
There isn’t one savings amount that works for every business. A person offering services from home may need far less money than someone opening a restaurant or retail store.
A Business That Costs $18,000 to Open May Need Much More
Imagine someone preparing to open a small neighborhood gift shop in Los Angeles.
After getting estimates for equipment, permits, deposits, and initial merchandise, the owner calculates that opening will cost $18,000.
That’s the amount needed to get the doors open.
But the owner doesn’t expect the shop to pay all its bills right away.
Based on a cautious sales estimate, the business may need another $4,000 a month to cover the gap between money coming in and money going out.
The owner also needs $2,500 a month for household expenses that won’t be covered by other income.
If the plan is to prepare for three months, the numbers look like this:
- Opening the business: $18,000
- Three months of business cash shortages: $12,000
- Three months of personal living expenses: $7,500
- Extra money for unexpected costs: $3,000
Total: $40,500.
These are hypothetical amounts, not average startup costs in Los Angeles. The business and household expenses are counted separately to avoid including the same bill twice.
And three months is only an example. Some businesses may need six months or longer before sales become dependable.
The owner should estimate how much cash will come in and go out each month, because the timing of bills matters too.
The important discovery is that the $18,000 needed to open is less than half the total amount in this example.
That’s why it’s worth doing the full calculation before committing your savings.
How Many Customers Will It Take to Pay the Bills?
Another question to answer before opening is how much you need to sell just to cover your business expenses.
That’s called breaking even.
Imagine a shop with $4,000 in monthly expenses that stay about the same, such as rent, insurance, and basic staffing.
The shop sells a product for $20. Buying and preparing that product costs $8.
That leaves $12 from each sale to help cover the $4,000 in monthly bills.
At that rate, the shop would need to sell at least 334 products a month, or roughly 11 a day in a 30-day month, to cover those expenses.
That’s not a sales forecast. It’s a target based on the example’s costs and prices.
The SBA’s break-even calculator can help you make the calculation for your own business.
And remember, breaking even on paper doesn’t always mean there’s enough cash in the bank. Inventory purchases, loan payments, taxes, and bills due before customers pay can still leave you short.
Finding the Money Can Be Another Challenge
For some entrepreneurs, calculating the money they need is the easier part. Finding that money is harder.
This is especially important to discuss when looking at Latino-owned businesses.
Stanford University’s 2025 State of Latino Entrepreneurship report, released in March 2026, documents financing challenges and differences in access to capital among Latino-owned businesses.
The research draws on businesses with at least one paid employee beyond the owner. That makes it valuable evidence about employer businesses, although it doesn’t describe every person trying to open a first business.
The report also examines venture capital, which generally supports companies pursuing rapid growth. But most people opening a bakery, salon, or neighborhood shop aren’t seeking that kind of investment.
They’re more likely to consider savings, a business loan, a community lender, or money from family or partners.
Each option comes with risks.
A loan has to be repaid even when business is slow. An investor may want a share of ownership. Using personal savings may leave less money available for family emergencies.
This article explores the barriers Latino entrepreneurs face when seeking business financing.
For someone who has limited access to financing, getting the startup calculation right matters even more. There may not be an easy way to borrow additional money if the business runs short after opening.
That doesn’t mean the business idea is out of reach. It means the owner needs to understand the risks before committing.
What if You Don’t Have Enough Money?
Finding out you need more money than expected can be discouraging.
But it may also help you find a less expensive way to begin.
A baker might start with preorders and a legally permitted home-based operation before renting a storefront.
A service provider might use a shared workspace instead of taking on a long lease.
Someone who already has a job might test whether customers will pay for the product or service before giving up a regular paycheck.
Parriva explored that approach in Don’t Quit Your Job Yet: Test Your Business Idea First.
Starting smaller won’t eliminate every expense, and California licensing, food-safety, and local zoning rules still apply where relevant.
But it may help you learn what customers want before putting more money at risk.
Your Startup Cash-Needs Checklist
Before opening, write down these numbers:
- Opening costs: What will you spend on equipment, permits, deposits, inventory, and other setup expenses?
- Monthly business cash needs: After estimating what customers will pay, how much more money will the business need each month?
- Personal living expenses: What household bills won’t be covered by another source of income?
- Months to prepare for: How long could it take before sales reliably cover business expenses?
- Emergency reserve: How much extra money do you need for unexpected costs?
- Money already available: How much savings or confirmed financing can you actually use?
Add the opening costs, projected monthly cash shortages, uncovered living expenses, and emergency reserve. Then subtract the money already available.
The result is an estimate of how much additional funding you may need.
Don’t rely on just one sales estimate. Check what happens if customers spend less than expected or the business takes longer to grow. A month-by-month cash plan for the first year will give you a clearer picture.
You can use SCORE’s startup-expense worksheet to organize your numbers or find free or low-cost business counseling through the SBA.
Opening a business can be a major opportunity for a family. It can also mean putting years of savings on the line.
Before signing a lease or buying equipment, make sure you know what the next several months could cost.
That calculation may tell you whether you’re ready to open, need to start smaller, or would be better off saving a little longer.
