How to read these results

These values are calculated from your current inputs. Check the input units and this calculator’s stated assumptions or included scope alongside the results.

Primary result: Estimated runway

Supporting value: Monthly net burn

Use the result for your next decision

Compare the primary result with your target or another option, then change only the conditions you want to test and recalculate. Before acting, also check the calculator-specific guidance and applicable conditions.

Keep up to three calculated result snapshots only for this page session and compare them with the current result. Inputs, URLs, and browser storage are not used.

Another calculator

Enter every monetary value in the same currency, such as KRW or USD. This calculator performs no FX conversion and keeps the currency unit you entered.

Calculation basis and checks

How it works

The calculator subtracts monthly inflow from monthly outflow to get net burn, then divides starting cash by net burn to estimate runway months. If net burn is zero or negative, it reports a non-consuming state instead of dividing by zero.

Worked example

For example, entering 120 of starting cash, 30 of monthly inflow, and 50 of monthly outflow in the same currency unit produces a monthly net burn of 20 and an estimated runway of 6 months.

Key assumptions

The estimate assumes the entered monthly cash inflow and outflow continue at the same level during the comparison period.
All monetary inputs are assumed to use the same currency unit; no foreign-exchange conversion is performed.

Limits and checks

Taxes, one-off expenses, financing, or investment proceeds affect the result only when you include them in the monthly inflow or outflow inputs.
The projected cash-out date uses an average month length, so the actual bank-balance depletion date can differ.
