Burn Rate in Small Business: Why Cash Disappears

Many small business owners don’t realise they have a burn rate problem until it is too late. Burn rate in a small business refers to how quickly your business is using cash without replacing it. If you are not tracking it, your business can run out of money — even while appearing profitable.

They are:

Paying salaries
Covering expenses
Keeping the business running

But every month, their bank balance is going down.

That is burn rate.

And if you don’t control it:

Your business will eventually run out of cash.

What Is Burn Rate in a Small Business?

Burn rate is simply:

How quickly your business is using cash without replacing it.

If your business spends:

R100,000 per month
But only generates R70,000

You are burning:

R30,000 per month

How to Calculate Burn Rate

Burn rate is simple to calculate:

Burn Rate = Monthly Cash Outflows – Monthly Cash Inflows

Example:
If your business spends R100,000 per month but only generates R70,000, your burn rate is R30,000 per month.

Why Burn Rate Matters More Than Profit

You can survive without profit for a while.

You cannot survive without cash.

Burn rate determines:

How long you can continue operating
How much pressure you are under
Whether you need funding — or urgent changes

How Long Can Your Business Survive? (Runway Explained)

Runway answers one question:

How long before I run out of money?

Example:

Cash available: R1,000,000
Monthly burn: R100,000

You have:

10 months before the business runs out of cash

This is not theoretical.

This is your survival timeline.

To know your burn rate and to know your breakeven point are critical if you want to calculate how long your business can survive.

What Causes High Burn Rate

From experience, the most common causes are:

Overstaffing too early
Poor pricing (low margins)
High fixed costs
Slow-paying customers
Over-investing in growth without return

What Most Business Owners Get Wrong

They focus on:

Revenue
Growth
Activity

But ignore:

How much cash the business is actually losing

By the time they realise, options are limited.

How to Reduce Burn Rate (Practically)

1. Fix Pricing First

If your margins are weak:

Every sale makes the problem worse

2. Cut Non-Essential Costs

Focus on:

What generates revenue
What supports operations

Everything else must be questioned.

3. Improve Cash Inflow

Invoice faster
Collect faster
Tighten credit terms

4. Delay Cash Outflows (Carefully)

Negotiate payment terms
Avoid paying earlier than necessary

5. Know Your Numbers Weekly

Not monthly.

If you are burning cash:

You need visibility now — not later
