How Big A Founder's Emergency Fund Should Be When The Salary Is Tiny
Standard emergency fund advice assumes a steady paycheck. Founders need a reserve sized for a company that might stop paying them on short notice.
Conventional advice says to keep a few months of expenses in cash. That rule of thumb was built for employees whose main risk is a layoff with some notice and perhaps severance. A founder's risk profile is different: the salary is usually below market, it can stop if the company runs short, and finding the next role can take longer than anyone expects.
Your personal reserve is what lets you make good decisions for the company. Without one, every hard choice about runway, layoffs or a weak acquisition offer gets made with your rent in the back of your mind.
Size it from your fixed costs, not your income
Start by listing the costs you cannot easily cut: housing, insurance, debt payments, childcare, groceries, utilities and transport. That is your monthly floor. Discretionary spending is not part of the calculation, because in a real emergency you would stop it.
Then estimate how long it would take you to replace your income if the company stopped paying you tomorrow. For some founders that is a few months of consulting; for others, particularly those who would need to wind a company down first, it is much longer. Multiply your monthly floor by that period and you have a starting target.
If you have a partner with a steady income, the household picture changes, and the target can reflect what their income would cover. If you are the sole earner, or your partner also works at the company, the target should be larger, because one bad quarter at the business would hit the whole household at once.
Add the costs founders forget
Health insurance is the big one. If your coverage runs through the company, losing the company can mean paying for continuation coverage or an individual plan at full price. Look up what that would cost in your state and add it to the monthly floor.
Next, add any tax bill you know is coming. Founders in pass-through entities owe tax on profit whether or not they received it in cash, and option exercises can create bills with no matching income. Money set aside for a known tax payment is not emergency money.
Finally, check whether you have signed a personal guarantee on an office lease, a credit card, an equipment loan or a line of credit. A guarantee means that if the company cannot pay, the creditor can come to you. If you have one, you either need a reserve that reflects it or a plan to get released from it.
Where to keep it
An emergency fund is meant to be boring and available. The usual homes are insured bank deposit accounts and short-term, high-quality instruments such as Treasury bills or government money market funds. Each has a different mix of safety, yield and access speed, and bank deposits and money market funds are protected in different ways.
Bank deposits are covered by FDIC insurance up to a limit per depositor, per insured bank, per ownership category. If your reserve is large, check whether you are above that limit at a single bank and how ownership categories affect your coverage, using the FDIC's own tools. Money market funds are not bank deposits and are not FDIC-insured.
Keep the reserve at a different institution from your company's operating accounts if you can. That separation is partly practical, so a problem at one bank does not freeze both, and partly psychological, so you are not tempted to see it as extra runway for the business.
Do not lend it to the company
The most common way founders drain their emergency fund is by quietly covering a payroll gap or a vendor bill. It feels temporary. Often it is not, and personal money put into a struggling company is at the back of the line if things go wrong.
If you decide to put personal money into the company, do it deliberately: document it as a loan or an equity investment with your board or co-founders, and only from money above your reserve target.
What to do this week
Write down your monthly fixed costs and your realistic time to replace income, and calculate the target. Add health coverage, known tax bills and any guarantee exposure. Compare that number with the cash you can reach within a few days.
If you are short, set a monthly transfer into a separate account and treat it as a fixed bill. If you are well above target, decide what to do with the excess on purpose rather than letting it sit. And put a reminder in your calendar to recalculate whenever your salary, family situation or guarantees change.
