Burn Rate Calculator
Summarize cash consumption for a small business or project budget. A positive net result means cash was consumed.
How the result changes
Only monthly cash outflows changes; all other inputs stay at your current values. The line illustrates the formula across the shown range. This is not a forecast of real-world outcomes.
About this calculation
Burn Rate Calculator calculates net monthly cash burn from monthly cash outflows, monthly cash receipts. Summarize cash consumption for a small business or project budget. The main answer uses currency units and follows the specific assumptions explained below.
Formula
Net burn = monthly cash outflows − monthly cash receipts; gross burn = monthly cash outflows.
Worked example
With Monthly cash outflows: 50000 currency units, Monthly cash receipts: 30000 currency units, net monthly cash burn is 20,000.00 currency units.
Inputs and calculation
Total cash paid during a representative month and subtract cash received during that same month. Keeping gross and net values separate shows whether receipts materially offset operating cash use. The displayed relationship is Net burn = monthly cash outflows − monthly cash receipts; gross burn = monthly cash outflows. Keep the fields' displayed units attached when reproducing this relationship by hand.
Worked numerical example
For example, enter monthly cash outflows 50,000 currency units, monthly cash receipts 30,000 currency units. Those inputs produce net monthly cash burn of 20,000 currency units. The same values also give gross monthly cash burn 50,000 currency units.
Holding the other example values fixed, change monthly cash outflows from 50,000 to 55,000 currency units. The main output becomes 25,000 currency units. This comparison isolates the effect of that one input.
How to read and use the result
A positive net result means cash was consumed. A negative result means receipts exceeded outflows in this simple monthly comparison; neither number by itself is a runway forecast. Summarize cash consumption for a small business or project budget.
Practical context
A business spending 50,000 cash and collecting 30,000 in one month burns 20,000 net that month. If it has 200,000 of available cash, dividing by the same 20,000 would suggest ten months of simple runway, but only if receipts and outflows stay unchanged.
Assumptions and scope
Both inputs are cash flows, not accrual revenue or booked expenses, and cover equal-length months. New financing proceeds are not ordinary operating receipts for this interpretation. Replace the example defaults with measured inputs for your situation and account separately for factors outside these fields.
Checks and common mistakes
A one-off equipment purchase can distort a single month's burn. Review several months and separate recurring operations from unusual cash events before making staffing decisions.
Common questions
What should I verify before using the Burn Rate Calculator result?
This calculator intentionally reports burn rather than assuming that forecast. A growth campaign, annual insurance payment or delayed customer collection can make one month atypical. Review a rolling cash schedule when planning payroll.
