fx Formula & Mathematical Methodology

Calculates Net Monthly Burn Rate = Monthly Burn Rate - Guaranteed Side Income. Financial Runway in Months = Current Liquid Savings / Net Monthly Burn Rate. Multiplies by 30.4 days for exact calendar days.

\text{Runway (Months)} = \frac{\text{Current Savings}}{\text{Monthly Burn} - \text{Passive Income}}

Real Numerical Example: $12,000 Savings with $2,800 Net Burn

Scenario Parameters:
Savings: $12,000 | Monthly Burn: $3,000 | Guaranteed Side Income: $200
Net Monthly Burn = $3,000 - $200 = $2,800. Runway = $12,000 / $2,800 = 4.29 Months (approx. 130 Days).

Your savings provide approximately 4 months and 9 days of complete living security before running out.
