The formula is already in B2, filled down to B6. Change any input and the result updates, or edit the formula to experiment.

How it works

ROUND's second argument counts decimal places. Positive numbers round to the right of the decimal point; negative numbers round to the left: -1 to tens, -2 to hundreds, -3 to thousands. Halves round away from zero, so 12,450 becomes 12,500.

=ROUND(A2,-2)

Result12400

  1. A212,449

    The value in A2.

  2. -2-2

    Makes the value negative.

  3. ROUND(A2,-2)12400

    ROUND: Rounds to a number of digits; negative digits round left of the decimal.

In Google Sheets

The same formula works in Google Sheets: =ROUND(A2,-2). We ran it in Google Sheets mode on the same data and it returns the same results.

Other ways to do it

Each one was run on the same example sheet.

FormulaResultWhen to use it
=MROUND(A2,100)12,400, 12,500, 8,800…MROUND rounds to any multiple, like 25 or 0.05, not only powers of ten.
=ROUNDUP(A2,-2)12,500, 12,500, 8,800…Different resultAlways rounds up to the next hundred, for budgets and capacity. Rounds up: 12,449 becomes 12,500.

Common mistakes

  • Formatting a cell to show no decimals only changes how it looks; the full value is still used in sums. ROUND changes the value.
  • Rounding each line and then summing can differ from rounding the total. Decide which one your report needs.

Try it yourself

Same data, empty answer cell. Your formula is graded instantly, then re-checked on changed data, so a typed-in number won't pass.

Round to the nearest 100 or 1000

In B2, round the forecast to the nearest hundred and fill down to B6.
