A calculator should make assumptions visible, not hide them
Everyday calculators are useful because they reduce arithmetic friction, but the result still depends on choosing the right relationship and entering the right units. A percentage calculation can use the wrong denominator; a loan estimate can omit fees; an age calculation can depend on calendar rules.
We use the surrounding explanations to make those assumptions easier to see. For decisions involving contracts, finance, medicine or other high-stakes contexts, use the tool for orientation and verify the result against an authoritative source.
Choose the next step by the problem you have
- Percent problem? Identify whether it is percent-of, what-percent or percentage change.
- Converting units? Estimate the direction before trusting the decimal.
- Comparing loans? Use scenarios, then verify against lender disclosures.
- Calculating age? Use calendar dates, not days divided by 365.
