Understanding Burn Rate and Cash Runway

Burn Rate: Burn rate is the rate at which a company spends its cash reserves over time. It is usually expressed as the amount of money lost per month. Burn rate helps businesses and investors understand how quickly funds are being used.

Formula:
Burn Rate = (Initial Balance − Final Balance) ÷ Duration (in months)

Cash Runway: Cash runway is the estimated time (in months) that a company can continue operating before running out of funds, based on the current burn rate.

Formula:
Cash Runway = Current Cash Balance ÷ Burn Rate per month

👉 Key Insight: Lowering your burn rate increases your runway, giving your business more time to become profitable or raise additional funding.

Formula to Calculate Burn Rate and Cash Runway

Burn Rate = (Initial Balance − Final Balance) ÷ Duration (months)

Cash Runway = Current Cash Balance ÷ Burn Rate (per month)

Examples of Burn Rate Calculation Using the Calculator

Example 1

Initial Balance = $50,000 | Final Balance = $4,200 | Duration = 61 months

Burn Rate = (50,000 − 4,200) ÷ 61 = $750.82 per month

Cash Runway = 4,200 ÷ 750.82 = 5.59 months


✅ Final Results:
Burn Rate = $750.82 per month
Cash Runway = 5.59 months

Example 2

Initial Balance = $120,000 | Final Balance = $60,000 | Duration = 12 months

Burn Rate = (120,000 − 60,000) ÷ 12 = $5,000 per month

Cash Runway = 60,000 ÷ 5,000 = 12 months


✅ Final Results:
Burn Rate = $5,000 per month
Cash Runway = 12 months

Example 3

Initial Balance = $80,000 | Final Balance = $20,000 | Duration = 10 months

Burn Rate = (80,000 − 20,000) ÷ 10 = $6,000 per month

Cash Runway = 20,000 ÷ 6,000 ≈ 3.33 months


✅ Final Results:
Burn Rate = $6,000 per month
Cash Runway = 3.33 months
