Frequently Asked Questions

Are the formulas transparent?

Each tool lists the formula and assumptions so you can audit the math.

Can I use decimals and different currencies?

Yes, inputs support decimals and we format results based on your locale.

Do you store my results?

No, everything stays in your browser unless you choose to copy it elsewhere.

Can I export a breakdown for stakeholders?

Copy the narrative summary or download the JSON block to paste into docs, tickets, or planning decks.

Do calculators handle scenario comparisons?

Use the side-by-side mode to duplicate inputs and tweak assumptions without rebuilding every field.

Are there guardrails for invalid inputs?

Inline validation flags out-of-range values and clarifies how each field affects the math.
