How the Burn Rate Gauge Works
Your emergency fund's longevity depends on how much you spend each month. A higher burn rate means your savings run out faster. This calculator shows how many months your savings will last at three different spending levels: essential only, frugal, and normal. Each tier gives you a different perspective on your financial runway. Enter total emergency savings and three monthly spend tiers. Essential covers housing, food, utilities, and insurance. Frugal adds modest discretionary. Normal reflects full lifestyle. Eighteen thousand savings divided by three thousand normal monthly burn shows six month runway on gauge. Stress burn adds COBRA six hundred monthly or removes partner income for conservative job loss plan.
The essential tier uses the bare minimum for survival: housing, food, utilities, and insurance. The frugal tier adds some modest discretionary spending. The normal tier reflects your current monthly spending. Comparing all three helps you understand your range of options during a financial emergency. Runway months equal savings divided by each tier burn rate. Milestone markers at 3, 6, 12, and 24 months show savings targets for each tier on the gauge. Stress burn adds COBRA six hundred monthly or removes partner income for conservative job loss plan. Lean burn cuts discretionary categories; normal burn reflects typical unemployed frugality not vacation mode.
Adjust each spending tier independently to model different scenarios. Run a lean scenario with only essential expenses to see the maximum runway, then layer in frugal and normal tiers to understand the trade off between comfort and longevity. Eighteen thousand savings divided by three thousand normal monthly burn shows six month runway on the gauge.
