What this calculadora actually does

Most Business tools bury the calculation. Burn Rate calculadora shows it. Punch in your figures, read the working, share the URL if you need a second opinion.

Rules of thumb lie at scale — the arithmetic holds up to a whiteboard argument. Decide whether you want gross or net, and commit — then model the numbers and the rest of this page explains what the answer means.

Break down gross and net burn rate from expenses and revenue, and translate into default-alive vs default-dead status.

Scenarios where Burn Rate calculadora pays off

"Burn rate formula"
"Gross vs net burn"
"Default alive"
"What is burn rate"
"How to calculate burn rate"
"Burn rate example"

When it isn't the right tool

Every tool has an edge where it stops being the right answer. Burn Rate calculadora is no exception:

For legally binding tax or medical decisions — cross-check with HMRC, NHS or a qualified professional.
For very large or very small extremes the rounding error outgrows the useful precision.
When the underlying rate or threshold has changed since the page was last reviewed — always verify with the primary source.
When the input you have is already a derived figure (net of something) — feeding it in as "gross" will double-subtract.

Mistakes we see over and over

Every time you model the numbers for a new scenario, one of these creeps in — it's worth knowing them ahead of time.

Mixing up units — grams in one field, ounces in another, then wondering why the answer is off.
Treating a percentage as a whole number. 20% means 0.20 in the maths, not 20.
Rounding at every step. Keep four decimals internally and only round the final number.
Using last year's thresholds. If the page isn't dated, assume it's stale and check GOV.UK.
Reading a tool like this as advice. It is maths, not a decision — the decision is still yours.

The sources behind the numbers

Where the maths needs an external authority, we cross-check against:

Y Combinator
