Most small businesses do not fail because of bad ideas.
They fail because something unexpected happens fuel prices rise, a major customer delays payment, power costs spike, or sales slow suddenly.
Without an emergency fund, even a profitable Nigerian SME can collapse under short-term pressure.
The question is not whether emergencies will happen.
It is whether your business has enough cash runway to survive them.
What Is an Emergency Fund for a Business?
An emergency fund is cash set aside strictly to keep the business running during disruptions.
It is not for expansion.
It is not for opportunistic spending.
It is for survival.
This fund covers essential expenses when normal cash inflows slow or stop.
Why Nigerian SMEs Need Emergency Funds More Than Most
Operating in Nigeria comes with unique volatility:
- Fuel price shocks
- Exchange rate fluctuations
- Power supply instability
- Policy changes
- Delayed customer payments
These factors make predictable cash flow difficult.
An emergency fund provides breathing room when conditions shift suddenly.

How Much Cash Runway Does a Nigerian SME Need?
There is no single number, but there is a clear framework.
The General Rule of Thumb
Most Nigerian SMEs should aim for 3–6 months of operating expenses as cash runway.
But this depends on your business type and risk level.
Step-by-Step: How to Calculate Your Emergency Fund
Step 1: List Your Fixed Monthly Costs
Include only expenses that keep the business alive:
- Rent
- Salaries
- Utilities and power
- Core software and tools
- Loan repayments
Exclude variable or discretionary costs.
Step 2: Identify Your Risk Profile
Ask yourself:
- Are your revenues predictable?
- Do customers pay on time?
- Are your costs sensitive to fuel or FX changes?
Higher uncertainty means a larger emergency fund.
Step 3: Choose Your Runway Period
Use this guide:
- 3 months: Stable income, low volatility
- 4–5 months: Moderate uncertainty
- 6 months: High volatility or seasonal income
Step 4: Do the Math
If your essential monthly expenses are ₦2 million:
- 3 months = ₦6 million
- 6 months = ₦12 million
That is your emergency fund target.

Common Mistakes SMEs Make
- Treating overdrafts as emergency funds
- Saving without separating the money
- Underestimating indirect costs
- Dipping into reserves for convenience
An emergency fund only works if it is protected.
A Short Story: The Business That Bought Time
A retail SME faced a sudden drop in sales after a fuel price increase.
Because they had four months of expenses saved, they did not panic.
They renegotiated supplier terms, adjusted pricing, and stabilized operations.
The emergency fund did not make them rich.
It kept them alive long enough to adapt.
Where Should You Keep Your Emergency Fund?
Accessibility matters.
- Separate business account
- High-liquidity savings or money market instruments
- Low risk, easy access
Avoid tying emergency funds to long-term investments.

Frequently Asked Questions (FAQs)
1. Is an emergency fund the same as business savings?
No.
Business savings are often used for future plans like expansion, marketing, or equipment.
An emergency fund is strictly for keeping the business alive when cash inflows slow or stop. It should not be touched for routine expenses.
2. Can a profitable business still need an emergency fund?
Yes.
Profitability does not guarantee liquidity. A business can be profitable on paper and still collapse if cash is unavailable when expenses are due. An emergency fund protects against timing gaps, not bad performance.
3. Should I use an overdraft instead of keeping cash aside?
Overdrafts are not emergency funds.
They increase liabilities, attract interest, and may be withdrawn unexpectedly. An emergency fund is your own cash, available immediately without new debt.
4. How fast should a small business build an emergency fund?
Gradually.
Start by setting aside a fixed percentage of monthly revenue or profits. Even one month of runway is better than none. Consistency matters more than speed.

5. What if my business income is seasonal?
Seasonal businesses should aim closer to six months of runway.
Emergency funds should cover the longest expected low-income period plus a buffer for unexpected shocks.
6. Should emergency funds be kept in naira or foreign currency?
It depends on your exposure.
If your major costs are local, naira is appropriate. If your business relies heavily on imports or FX-priced inputs, holding a portion in foreign currency may reduce risk.
7. How do I stop myself from dipping into the emergency fund?
Separation is key.
Use a dedicated account and treat the fund as non-negotiable. If spending from it does not prevent business shutdown, it probably does not qualify as an emergency.
8. How often should I review my emergency fund size?
At least every six months, or whenever your costs or risk profile change.
Rising fuel prices, new loans, staff increases, or FX exposure all affect how much runway you need.
9. Can startups or very small businesses realistically maintain an emergency fund?
Yes, but the amount may be smaller at first.
Emergency funds scale with your business. What matters is building the habit early, not waiting until the business is “big enough.”
10. How does Zaccheus make emergency fund planning easier?
Zaccheus removes guesswork by showing you:
- True fixed costs
- Real cash burn rate
