What is Cash Burn Rate? How Do You Calculate Burn Rate?

Burn Rate Definition: Cash burn rate is the rate at which a company uses up its cash reserves or cash balance.

Essentially, it’s a measure of the net-negative cash flow. If you need a refresher on what cash flow is, check out this article.

When you’re thinking about cash burn rate, you’re asking:

  • How fast are you using up your cash reserves?
  • Or is your cash moving the other direction, and building up a healthy balance from positive cash flow?

How do you calculate cash burn rate?

Current Burn Rate = Cash Balance in Prior Month – Cash Balance in Current Month

Monthly Burn Rate = (Cash Balance Beginning of Period – Cash Balance End of Period) / # of Months in Period

To determine the burn rate for a selected period, you find the difference between the starting and ending cash balances for the period of time— say a quarter.

Did you lose or gain cash?

Then we divide that total by the number of months in the selected period.

The result is a monthly value.

How to calculate cash burn rate

For example, say a company started last quarter with $200K in the bank but ended with only $110K. That’s a loss of $90K in cash over three months—a burn rate of $30K per month.

From a cash runway perspective, that suggests that the company now has just over three months of cash runway or cash on hand. They need to lower their burn rate and get cash flow positive soon.

Now that you know your cash burn rate, you can see how long the current burn rate is sustainable. By calculating your cash runway.

What is a cash runway?

Your cash runway is how long your cash will last at your current cash burn rate. When you’re out of cash runway, you’re out of cash and you’re out of time.

The typical pattern for startups is to get funded, use that cash to build the business, and then aim to get to positive cash flow before the money runs out. It’s a big concern for funded startup companies—particularly if you’re working with venture capital or angel investment.

The same metric is useful for mature businesses too. How fast are you growing your cash reserve? Or, are you strategically investing that money to fund faster growth? Whatever your plans, be sure to keep an eye on this metric to make sure you are hitting your targets.

How do you calculate cash runway?

Cash Runway = Total Cash Reserve / Burn Rate

To figure out your cash runway (how long the company has until it runs out of cash), take the rest of the money left in the cash reserves and divide it by the burn rate. For example, if there is $200,000 left and the burn rate is $50,000 per month, it will take 4 months for the company to run out of cash.


Is high or low cash burn rate better?

It’s often best to have a negative cash burn rate. That means you are building your cash reserves, not using them up. There are certainly cases where investing your cash in growth is a good idea, though: startups, obviously, but also bootstrapped companies that are trying to grow. Just make sure you plan for that cash burn and then track your progress.

If you burn through your cash reserves faster than expected, you may end up in trouble.

How do you reduce your cash burn rate?

If your cash burn rate is higher than you want, the numbers to change are pretty simple. You need to increase your incoming cash, decrease your outgoing cash, or both. Here are ideas on how to do those things:

1. Increase your revenue

Look for ways to boost your traffic, get more prospects into your pipeline, increase your conversion or close rates, or raise your pricing. More sales should translate into more cash coming in.

2. Reduce your payroll expenses

For labor-intensive businesses, deferring new hires, laying off nonessential workers, or limiting benefits can lead to big savings. Make sure any cuts are smart and sustainable, though.

3. Reduce your direct costs

For low-margin businesses, finding ways to minimize unnecessary inventory of raw materials and other direct costs can make a big difference in cash flow.

4. Reduce or defer other expenses

Take a close look at your budget. Are there expenses that aren’t contributing to your company’s success?

5. Ditch unprofitable revenue streams

It’s not uncommon for businesses, who are looking to grow, to offer secondary products or services that don’t break even. Put any non-revenue generating offerings on hold to help regulate your Cash Burn Rate. You can always relaunch at a later time.

6. Encourage cash sales

Cash sales are great: you get the money right away instead of waiting for it. Make sure you are offering credit terms selectively and smartly, rather than just converting what would have been immediate transactions into delayed ones.

7. Bill sooner and collect faster

When you do offer credit to customers, be sure to bill them promptly. Clearly state the credit terms and follow up with appropriate collection activities if they don’t pay on time. Adding late-payment charges may also help more timely payments.

8. Pay your bills slowly

Unless there’s a discount or other incentive for paying sooner, don’t pay your bills any faster than you have to. Take advantage of the agreed payment terms to hold onto your cash longer.

9. Sell off excess inventory

Extra inventory is still valuable, but it’s not as useful as having the equivalent amount of cash. Consider offering sales promotions or discounts to sell off what you don’t need for regular sales.

10. Consider using a factoring service

Factoring is a financial service in which a business sells off its bills receivable to a third party at a discounted rate. If you cannot get customers to pay their invoices on time, it may be worth looking into such a service.

11. Hold off on major purchases

If cash is tight, that big capital expenditure may need to wait—unless it’s an investment that will start paying off right away.

12. Consider refinancing debts

Using too much cash to repay debts? Check with your creditors about options to refinance with lower payments.

13. Raise additional funds

If you’ve done all you can to affect your incoming and outgoing cash (your cash flow), but your burn rate is still too high—and, crucially, you are confident that your business can be successful—you may need to do more fundraising. Be sure to do this as early in the process as possible, since a business running low on cash may strike potential lenders as too risky.
