What the result means

Tip amount is the number to carry forward from this tip calculation. Bill amount multiplied by tip percent. Read the main estimate first, then compare it with the assumptions and secondary outputs before using it in a decision. Use total with tip, tip per person, and total per person to explain why tip amount moved when an input changed. Compare the result with the source document or quote that will actually govern the decision. Check rates, dates, fees, taxes, local rules, compounding, and omitted real-world charges before treating the result as final.
