How to compare startup burn-rate reductions
Compare expense cuts and faster collections without confusing one-time cash improvements with recurring burn savings.

Which change reduces burn the most?
Compare the recurring cash effect of each change using the same month and starting assumptions. An expense reduction lowers gross and net burn; faster payment may improve this month’s cash without permanently changing the recurring economics.
A practical comparison
An illustrative startup spends $90,000 and collects $40,000 monthly, leaving $50,000 net burn. It considers three changes:
| Change | Expenses | Receipts | Net burn |
|---|---|---|---|
| Baseline | $90,000 | $40,000 | $50,000 |
| Remove $8,000 recurring expense | $82,000 | $40,000 | $42,000 |
| Add $8,000 recurring collections | $90,000 | $48,000 | $42,000 |
| Collect $8,000 overdue invoice once | $90,000 | $48,000 this month | $42,000 this month |
The last two rows have the same immediate result but different implications for next month. Do not carry a one-time collection forward as though every future month will benefit.
Account for the cost of a change
If cancelling a service saves $8,000 monthly but requires a $12,000 termination payment, the first month has $94,000 of expenses: $90,000 − $8,000 + $12,000. Net burn rises temporarily to $54,000. The simple cash payback on the termination cost is 12,000 ÷ 8,000 = 1.5 months, assuming the savings persist.
Enter the transition month and steady-state month separately. This prevents a useful longer-term reduction from being mistaken for an immediate cash rescue. It also exposes whether there is enough cash to pay for the transition.
Questions before changing the plan
Should I average the last three months?
An average is useful only if you explain unusual payments and collection timing. Keep the raw monthly numbers available and compare them with the next month’s actual commitments.
Does lower burn prove a better business?
No. This calculator does not measure the effect on retention, delivery capacity, or future revenue. Pair the cash saving with the operational change required to achieve it, and check the resulting runway separately.
