It is especially useful for startups, project-based businesses, and companies investing ahead of revenue. This calculator converts the difference between a beginning cash balance and an ending cash balance into a monthly rate, annualizes that rate, and estimates how long the ending balance could last if the same pace continued.\u003c\/p\u003e\n    \u003cp\u003eThe calculation is a planning indicator, not a complete cash-flow statement. A single burn-rate figure compresses many movements—customer receipts, payroll, marketing, capital expenditure, financing, and one-time payments—into one net change. For operating decisions, reconcile it with a detailed cash-flow forecast and current bank balances. The U.S. Small Business Administration’s guidance on \u003ca href=\"https:\/\/www.sba.gov\/business-guide\/manage-your-business\/manage-your-finances\" target=\"_blank\" rel=\"noopener noreferrer\"\u003emanaging business finances\u003c\/a\u003e provides useful context for cash controls and financial recordkeeping.\u003c\/p\u003e\n\n    \u003ch2\u003eHow to enter the inputs\u003c\/h2\u003e\n    \u003ch3\u003eInitial balance\u003c\/h3\u003e\n    \u003cp\u003eEnter the cash and cash equivalents available at the beginning of the measurement window. Use the same account scope at both dates. For example, do not include a restricted deposit in the initial balance and exclude it from the final balance. A higher initial balance does not change the monthly burn rate by itself unless the final balance or duration also changes, but it increases the runway available at the start of the period.\u003c\/p\u003e\n    \u003ch3\u003eFinal balance\u003c\/h3\u003e\n    \u003cp\u003eEnter the comparable cash balance at the end of the period. A lower final balance produces a larger positive burn rate. A final balance equal to the initial balance produces zero net burn. A final balance above the initial balance produces a negative burn rate, which means cash increased during the period. In that case, a finite “cash-out” runway is not meaningful because the observed trend is cash-flow positive.\u003c\/p\u003e\n    \u003ch3\u003eDuration and duration unit\u003c\/h3\u003e\n    \u003cp\u003eEnter the time between the two balance dates and choose months or years. The duration must be greater than zero. A longer duration spreads the same cash reduction across more months and therefore lowers the monthly burn rate. When you switch between months and years, the calculator converts the entered duration rather than merely changing the label. Use exact months where possible; an observation window that is too short can be distorted by payroll timing, annual insurance, tax payments, or a large customer receipt.\u003c\/p\u003e\n\n    \u003ch2\u003eFormula and result interpretation\u003c\/h2\u003e\n    \u003cdiv class=\"br-formula\"\u003eMonthly burn rate = (initial balance − final balance) ÷ duration in months\u003c\/div\u003e\n    \u003cp\u003e\u003cstrong\u003eMonthly burn rate\u003c\/strong\u003e is the average net cash reduction per month. A high positive value means cash is being consumed quickly. A value near zero means the two balances were similar. A negative value means cash increased. The \u003cstrong\u003eannualized burn\u003c\/strong\u003e multiplies the monthly rate by 12; it is a run-rate comparison, not a prediction that every month will be identical.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eCurrent cash runway\u003c\/strong\u003e divides the final balance by the positive monthly burn rate. It estimates the number of months the current balance could support under a constant-rate assumption. A short runway can signal the need to reduce spending, accelerate collections, revise hiring plans, or begin financing discussions. A long runway gives more time, but it should still be stress-tested because costs and revenue rarely stay flat.

It is the numerator of the burn-rate formula. \u003cstrong\u003eRunway at period start\u003c\/strong\u003e applies the measured monthly rate to the initial balance, showing how much total runway existed before the observed period elapsed. With a stable positive burn rate, starting runway should approximately equal the observed duration plus current runway.\u003c\/p\u003e\n\n    \u003ch2\u003eHow to read the chart and table\u003c\/h2\u003e\n    \u003cp\u003eThe allocation chart divides the initial balance into two real components: cash used during the observation period and the final cash balance. It appears only when those categories are valid and positive. If the business added cash rather than burned it, the calculator replaces the donut with a concise explanation instead of drawing a misleading breakdown.\u003c\/p\u003e\n    \u003cp\u003eThe balance projection chart shows the observed movement from initial to final balance and, when burn is positive, a projected extension toward zero. This is a straight-line scenario, not a probability forecast. The monthly table uses the same model data and shows opening balance, cash change, and closing balance for each period. The final row is capped at zero so the schedule does not create an artificial negative cash balance.\u003c\/p\u003e\n\n    \u003ch2\u003ePractical use, tradeoffs, and common mistakes\u003c\/h2\u003e\n    \u003cp\u003eTrack burn rate consistently—often monthly and on a rolling three- or six-month basis—to separate trend from timing noise. Compare gross cash outflow, net burn after receipts, budget, and actual results. The calculator uses net balance change, so a financing inflow or asset purchase can materially alter the result.
