If you are one of those persons who work with statistical data or analyze data a lot, then this formula might be useful for you in so many ways. Here we will learn to round a number to the nearest 1000, 100, and 10.
Round a Number to the Nearest 1000, 100, 10 with the ROUND Function
In Excel, there’s a function called ROUND that you can use to round a number to the nearest 1000.
The round function is useful when you want to round large numbers for simplification, especially when useful in financial summaries, dashboards, or inventory reports.
Here I have the number “123456789”, and I want to round this number.
You can use the following steps.
- First, edit cell B1, and start entering the ROUND function “=ROUND(“.
- Now, refer to cell A1, where we have the number that you want to round.
- Next, in the second argument, enter -3.
- In the end, enter the closing parenthesis and hit Enter to get the result.
=ROUND(123456789, -3) → 123457000 (rounded to the nearest 1000)
The moment you hit enter it returns 123457000 which is then rounded to the 1000 version of 123456789. As you have the last four numbers 6789, it has rounded to 7000.
But if you change that number to 123456489, where you have 6489 in the end, the same function rounds it downwards to 123456000.
The ROUND function is quite smart to identify on which side the number needs to be rounded. But there might be a situation where you need to ROUND down or up a number to the nearest 1000.
In the same way, you can use the ROUND function to round a number to the nearest 100. For this, you just need to use the -2 in the num_digit argument.
=ROUND(A1,-2)
=ROUND(123456489, -2) → 123456800
And if you want to round a number to the nearest 10, then you use the ROUND function in the following way.
=ROUND(123456, -2) → 123500 (rounded to the nearest 100)Note – When you are using the Round function in Excel, you need to remember one thing that in the num_digits argument, the negative values always round to the left of the decimal (number part), while positive values are rounded to the right (decimal parts). When you are rounding a number to the nearest 1000, 100, or 10, you always need to specify a minus number as -3, 2, or -1.
=ROUNDDOWN(123456789,-3) = 123456000 =ROUNDUP(123456489,-3) = 123457000
Round a Number to Nearest Nth Value
Let me ask if you want to write a formula that allows you to round to the nearest Nth value. Isn’t this great?
Here’s a formula that rounds a number to the nearest specified multiple using Excel’s MROUND function.
For example, if you want to round 123456789 to the nearest 100, you would enter the following formula in a cell:
=MROUND(123456789, 100)
This returns 23456800. And to round to the nearest 1000, you would use:
=MROUND(123456789, 1000)
Different Approach with ROUND and Basic Formula
You can also use basic arithmetic with the MROUND to write a formula that allows you to use any multiple to get the number.
=ROUND(number / multiple, 0) * multiple =ROUND(123456789 / 100, 0) * 100
This formula is perfect if MROUND isn’t suitable (e.g., it’s not available in your version of Excel).
Other Methods to Round a Number to the Nearest 1000
There are a few more ways that you can use it:
- FLOOR Function: FLOOR(123456789,1000) = 123457000
- In this function, you need to use a positive 1000 to round a positive number and a negative -1000 to round a negative number.
- CEILING Function: CEILING(C1,1000) = 123457000
- In this function, you need to use a positive 1000 to round a positive number and a negative -1000 to round a negative number.
