Small business owners face one of the biggest challenges in managing cash flow.

Many focus only on revenues, but in reality, the sustainability of a business is determined not only by revenues but also by the period during which the company can operate until the funds run out. This period is called financial runway.

What is financial runway

Financial runway means how long your business can continue to operate with the current cash reserves if nothing changes in revenues or expenses.
Think of it like a fuel tank: the more fuel there is, the longer the car will run.

For example, if your business spends $10,000 a month and you have $50,000 in the bank, then your runway is only five months. During that time, you need to either increase revenues, cut expenses, or secure new funding.

How to calculate your business's runway

The calculation is very simple:
Runway = cash reserves ÷ monthly net expenses

• Cash reserves. The amount of money available in your business accounts, including savings.
• Monthly net expenses. Monthly expenses minus revenues.

If your expenses exceed your revenues, you are quickly depleting your reserves.

The role of fixed and variable costs

To understand your runway, it is important to distinguish between fixed and variable costs.

• Fixed costs. Do not change regardless of your revenues. For example, rent, salaries, software subscriptions.
• Variable costs. Increase or decrease with the level of business activity. For example, the cost of purchasing goods, shipping, freelance services.

During a downturn, fixed costs can pose the greatest risk as they remain unchanged even when revenues decline. Meanwhile, variable costs provide flexibility. The best option is to have at least 30% variable costs to allow for quick adjustments.

5 ways to extend your financial runway

1. Cut fixed costs

   • Cancel unused subscriptions.

   • Replace salaried positions with hourly contractors.

   • Review rental and supplier contracts.

2. Stabilize revenues

   • Invest in a membership or subscription model.

   • Encourage customers to pay in advance with discounts.

3. Improve payment terms

   • Negotiate longer payment terms with suppliers.

   • For example, agree on 30 days instead of 10 days.

4. Consider short-term financing

   • Credit lines, bridge loans, or invoice factoring.

   • This can help buy time until revenues stabilize.

5. Focus on profitable areas

   • Invest more in areas that generate high revenue.

   • Stop ineffective programs.

Why this is especially important now

In an uncertain economic environment, only those who control their cash flows and understand their financial runway succeed.
A proper assessment of the runway allows you to:

• make confident decisions,
• invest at the right time,
• and say "no" to unnecessary customers or projects when needed.

The financial runway is a reality check. When you see it clearly, you can take steps to extend it, ensuring the survival and growth of your business.
