What Is a Burn Rate? And Why Pricing Is the Fastest Way to Fix It

Burn rate is the speed at which a company spends its cash reserves, normally expressed per month. If you hold $2 million and your bank balance falls by $150,000 a month, your burn rate is $150,000 and you have roughly 13 months before the money is gone.

It is the most watched number in any company that is not yet profitable, because it converts every other decision into a deadline. What most teams underestimate is how much of it is determined by pricing rather than by spending.

Gross burn and net burn

Gross burn = total cash operating expenses in the month. Payroll, hosting, tooling, rent, marketing. Everything going out, with no credit for revenue.

Net burn = cash out minus cash in. This is the number that actually depletes the bank account, and the one investors mean when they ask about burn.

The gap between them matters. A company with $400,000 gross burn and $360,000 of monthly cash collections is burning $40,000. Cutting gross burn by 10 percent saves $40,000 a month. Raising collections by 11 percent does the same thing, and unlike the cost cut it compounds and does not damage the business.

Runway

Runway in months = cash on hand / net monthly burn

Two refinements make it honest:

• Use a three-month average of net burn. One quiet month is not a trend.
• Model runway forward, not backward. Hiring plans, annual contract renewals and rising inference costs all change the number. If burn grows as you grow, a flat calculation overstates your runway.

The practical rule: below 6 months of runway you are in crisis and every decision is defensive. Twelve to eighteen months is where you can still make strategic choices, including repricing. Repricing takes weeks to design and a quarter or two to show up in cash, so it has to be started while you still have room.

Why cost cutting is the slower lever

Cutting costs is popular because it is immediate and fully under your control. It is also capped and self-limiting. You can only cut the same dollar once, most of your cost is people, and cutting people reduces the capacity you need to grow out of the problem.

Revenue-side changes are harder to start and much more powerful once running:

• A price increase reaches the bank account almost intact. An extra $20,000 a month of recurring revenue at 75 percent gross margin adds about $15,000 to cash, with no new headcount and no new acquisition spend.
• Gross margin multiplies everything. If margin sits at 50 percent because inference and tool costs scale with usage, every dollar of revenue only buys 50 cents of runway. Fixing the value metric so revenue tracks delivery cost raises margin on all revenue, existing and future.
• Expansion revenue is the cheapest cash in the business. A model that grows with customer value produces new revenue with no acquisition cost attached, which improves net burn twice over.
• Payback period is a burn decision. A 24-month CAC payback means each new customer deepens your burn for two years before helping. Halve payback and you can grow at the same rate on materially less cash.

The pricing signals that show up as burn

• Revenue grows and burn grows with it. Delivery cost is rising in step with usage while price is fixed per seat. Structural margin problem.
• Heavy discounting to close. Every discount is a direct transfer from your runway. Usually a sign that list price is not backed by willingness-to-pay evidence.
• Flat net revenue retention. All growth must be bought, so growth and burn are locked together. See churn rate analysis.
• Monthly billing on annual value. Annual prepay pulls twelve months of cash forward per customer. Nothing else changes runway that fast without touching costs.

Five ways to extend runway without cutting the team

1. Move to annual prepay with a modest discount. Immediate cash timing improvement.
2. Fix the value metric so revenue rises with usage instead of margin falling with it. Start with the pricing models guide.
3. Raise price on new customers first. No churn risk on the existing base, and it gives you evidence before a wider change. Test points with Gabor-Granger.
4. Unbundle the expensive parts. Features that carry real delivery cost should be add-ons rather than included in every plan.
5. Cut the acquisition spend with the worst payback before you cut anything else. It is the largest controllable line and the easiest to measure.

The short version

Burn rate is cash out minus cash in, and runway is what is left divided by that. Most teams treat it as a cost problem because costs feel controllable. In subscription and AI businesses it is usually a pricing problem: the wrong unit, an unsupported price, or a margin that erodes as customers succeed. Fix the model and the burn improves on every customer you already have.
