What is Burn Rate?
Burn Rate is the rate at which a company spends its cash reserves, typically measured on a monthly basis. For startups and pre-profitable SaaS companies, burn rate is a critical survival metric. Gross burn rate is the total cash spent per month, while net burn rate accounts for incoming revenue. Tracking burn rate alongside your cash runway helps founders and investors understand how long the business can operate before it needs to reach profitability or raise additional funding.

The Formula
Monthly Burn Rate = (Cash Balance at Start − Cash Balance at End) / Number of Months
Worked Examples
3-Month Burn Rate
A startup had $800K in January. By end of March, it had $560K.
- Cash decrease: $800K − $560K = $240K
- Period: 3 months
- Monthly burn = $240K / 3
Gross vs Net Burn
A company spends $120K/month total expenses and generates $40K/month in revenue.
- Gross Burn = $120,000/month (total cash out)
- Net Burn = $120,000 − $40,000 = $80,000/month
What Is a Good Burn Rate? Industry Benchmarks
| Stage / Context | Typical Value | What It Means |
|---|---|---|
| Pre-Revenue Seed | $20K – $80K/month | Team of 3–8, product in development. |
| Early Revenue ($0–$1M ARR) | $50K – $200K/month | Building sales and marketing functions. |
| Series A ($1M–$5M ARR) | $200K – $600K/month | Scaling GTM and engineering teams. |
| Efficiency Benchmark | Burn Multiple < 2x | Burn Multiple = Net Burn / Net New ARR. Below 2x is considered efficient. |
How to Improve Burn Rate
Track Burn Multiple
Burn Multiple = Net Burn / Net New ARR. A Burn Multiple below 1.5x is excellent — meaning for every $1 of new ARR, you burn less than $1.50. This metric, popularized by David Sacks, is a better efficiency signal than raw burn rate.
Audit Headcount-Related Costs
Salaries, benefits, and recruiting typically represent 60–80% of SaaS burn. Ensure every role has a clear ROI tied to revenue or product milestones. Headcount additions should be preceded by a clear demand signal.
Negotiate Annual Contracts for Critical Vendors
SaaS tools, cloud infrastructure, and office space often have annual prepay discounts of 10–20%. Consolidating vendor payments can reduce monthly cash outflow meaningfully.
Improve Revenue Mix Toward Annual Plans
Annual contracts front-load cash — reducing effective net burn. Offering annual discounts to monthly subscribers improves both cash position and burn rate in the short term.
Burn Rate vs. Related Metrics
Burn Rate vs. Runway
Burn rate is the speed; runway is the distance. Runway (months) = Cash Balance / Monthly Burn Rate. Reducing burn rate directly extends runway without raising additional capital.
Burn Rate vs. Burn Multiple
Burn Multiple (Net Burn / Net New ARR) adds the revenue efficiency dimension that raw burn rate lacks. A $200K/month burn generating $300K in new ARR is far more efficient than a $200K/month burn generating $50K in new ARR.
Common Mistakes When Calculating Burn Rate
Confusing Gross Burn with Net Burn
Gross burn is total cash spent. Net burn is cash spent minus revenue received. Use net burn to measure actual cash consumption and runway. Use gross burn to understand total operating cost.
Calculating Burn on Too Short a Window
Single-month burn rates are noisy due to one-time payments (annual SaaS contracts, quarterly bonuses). Use a 3-month rolling average to get a smoother, more representative burn rate figure.
Not Updating Burn Projections as Revenue Grows
Burn rate models that assume flat revenue will overestimate future cash needs. As MRR grows, net burn shrinks. Update burn projections monthly to incorporate actual revenue performance.
