ROUND Formula Generator

Round a number to a set number of decimal places, or left of the decimal to tens, hundreds, and thousands.

ROUND

Round a number to a set number of decimal places, or left of the decimal to tens, hundreds, and thousands.

Math

The value to round. Can be a cell like A2, a number, or a calculation such as A2*1.0825.

2 keeps cents, 0 gives whole numbers, and negatives round left of the decimal point (-3 is the nearest thousand). Excel requires this argument, so leave a value here.

=ROUND(A2, 2)

Worked Example

A supplier quote of 18,432 needs to be rounded to the nearest thousand for a summary slide.

=ROUND(18432, -3)

Returns: Returns 18000. The negative num_digits rounds left of the decimal point, and -3 means the nearest thousand.

Checks Before You Paste

  • num_digits is a position, not a count of significant figures: 2 rounds to cents, 0 to whole numbers, and negative values round left of the decimal point, so -1 is the nearest ten, -2 the nearest hundred, and -3 the nearest thousand.
  • ROUND breaks ties away from zero, so ROUND(2.5, 0) is 3 and ROUND(-2.5, 0) is -3. ROUNDUP always moves away from zero, ROUNDDOWN always moves toward it, and MROUND(number, multiple) snaps to a step like 0.05 or 25 instead of a power of ten.
  • Changing a cell's number format only changes what you see: the stored value keeps every decimal, so a column that displays 10.00 + 10.00 can total 20.01. ROUND changes the value itself, which is why totals should be built from rounded cells rather than rounded displays.
