TallyBench is a set of everyday calculators built to answer one question at a time — no account, no app download, no data stored anywhere but your own browser tab.
Multiply the bill by the tip percentage, then divide the total by the number of people. TallyBench does this live as you type.
BMI is a screening estimate based on height and weight only — it doesn't account for muscle mass, age, or frame size, so treat the category as a starting point, not a diagnosis.
