Cross-check when the decision matters. Run a second scenario with rounded inputs or a different path to the same quantity so you do not rely on a single fragile chain of arithmetic.
Write down units and rounding rules next to the answer. Half of spreadsheet mistakes are inconsistent units or silent rounding; noting assumptions makes the number usable a month later.
