Measure how quickly operating cash outflows consume available cash and translate that relationship into an estimated cash runway expressed in months.
This Excel workbook is designed for founders, business owners, controllers, and finance teams that need a focused view of cash sustainability. Enter annual cash outflow components and average cash balances across five periods, then review the calculated operating cash totals, average monthly cash outflow, cash burn ratio, and year-by-year chart.
Quantify runway
Convert the relationship between average cash on hand and average monthly operating cash outflow into a cash burn ratio measured in months.
Track the direction of change
Compare five annual periods to see whether the company is extending or shortening the time its cash position can support operations.
Support spending decisions
Use the calculated view to discuss cost reductions, cash preservation, financing timing, and the pace of planned operating commitments.
What does the cash burn analysis help you evaluate?
The workbook brings the main cash burn inputs and outputs into one structured calculation so users can assess liquidity pressure without mixing the metric with broader profitability or valuation analysis.
Operating cash consumption: organize cash payments, interest paid, and corporate tax paid for each annual period.
Total operating cash out: consolidate the entered cash outflow components into a period total.
Average monthly operating cash out: translate annual operating cash usage into a comparable monthly amount.
Cash coverage in months: relate the average annual cash balance to average monthly operating cash outflow through the cash burn ratio.
Multi-period trend: compare the ratio across five years and identify whether liquidity coverage is improving or deteriorating.
What is inside the workbook?
The visible worksheet combines editable assumptions, calculated rows, and a presentation chart. Yellow cells identify the values entered for each financial year, while the summary rows calculate operating cash usage and the resulting cash burn ratio.
Editable cash inputs
Populate cash payments, interest paid, corporate tax paid, and average annual cash balance for each of the five displayed periods.
Calculated cash metrics
Review total operating cash out, average monthly operating cash out, and the cash burn ratio generated from the entered values.
Annual comparison chart
Use the column chart to communicate how the cash burn ratio changes from one year to the next.
The worksheet shows five financial years, highlighted input cells, calculated operating cash outflows, average cash balances, cash burn ratios, and a chart for period-to-period comparison.
See the calculation and trend together
The table keeps the assumptions and derived metrics visible in the same view. This makes it easier to trace a change in the ratio back to its underlying cash outflow or cash balance input, while the chart provides a concise visual summary for management discussions. Because the ratio is expressed in months, a higher result represents more cash coverage at the displayed spending level, while a lower result indicates less coverage. This helps teams judge whether cash-preservation actions are meaningfully extending runway.
How do you use the template?
Set the five periods
Use the annual columns to represent the historical or forecast years you want to compare.
Enter cash outflows
Fill in cash payments, interest paid, and corporate tax paid for each period using a consistent unit of measure.
Add average cash balances
Enter the average annual cash balance that corresponds to each period so the coverage calculation is based on comparable data.
Review the outputs
Check total operating cash out, average monthly cash out, and the cash burn ratio, then use the chart to discuss trends and timing decisions.
Who is this template for?
The workbook is appropriate for startup founders monitoring runway, business owners managing liquidity, controllers preparing internal cash reviews, and finance teams comparing cash sustainability across annual periods. It is especially useful when the immediate question is how long current cash resources can support the observed level of operating cash use. Because the worksheet focuses on a specific cash burn ratio, it works best as part of a broader cash-planning process rather than as a replacement for a complete cash flow forecast.
