Separate gross burn from net burn so the runway answer reflects the actual cash draw.
Startup Finance
Burn-rate and runway analysis that avoids spreadsheet panic.
Use current cash, recurring monthly inflows and outflows, and one-time cash demands to calculate gross burn, net burn, runway, and buffer requirements quickly.
Direct answerA burn-rate and runway calculator shows gross burn, net burn, and how many months of cash remain at the current operating pace, then adds a buffer view for planning.
Browser-first workflowFunctional tool on topBuilt for finance operators
1. Build the scenario
CalculatorUse current unrestricted cash and recurring monthly inflows and outflows. One-time planned cash demands reduce available runway.
Enter assumptions or load a sample scenario to see the results.

What this tool is built to solve
A burn-rate and runway calculator shows gross burn, net burn, and how many months of cash remain at the current operating pace, then adds a buffer view for planning.
Reduce available cash for near-term one-time uses before calculating months remaining.
Use the buffer view to show the gap between current cash and the desired runway threshold.

How to use burn rate & runway calculator well
This section is written for searchers, answer engines, and busy finance teams: direct definitions, practical steps, and concrete follow-up guidance.
A burn-rate and runway calculator shows gross burn, net burn, and how many months of cash remain at the current operating pace, then adds a buffer view for planning.
Founders, startup finance teams, operators, and investors.
Current cash, monthly inflows, monthly outflows, one-time demands, and target runway buffer determine the answer.
Workflow
Four practical steps
Use the tool as a fast decision layer. The goal is to move from raw assumptions to a usable finance answer before you open a larger model.
1
Enter current cash.Start with the inputs or row data that define the current scenario.
2
Add recurring monthly flows.Add the comparison layer or second driver that changes the answer most.
3
Subtract one-time planned uses.Review the output and isolate the signal that matters most.
4
Review the buffer gap.Use the result in the next planning, review, or finance discussion.

Why This Page Exists
Built to close the gap between a formula and a usable finance decision
Most search results either define the metric or sell a larger platform. This page solves the immediate job first: use the tool, see the answer, and understand what it means before you move into a deeper workflow.
The functional tool stays on top so users can solve the immediate problem before reading a guide.
The result cards explain what the output means instead of leaving users with a raw number.
Ledger Summit can build richer finance tooling later, but this page delivers value now.
