Round to the Nearest Dollar Formula

The formula for rounding to the nearest dollar can be expressed as:

Rounded Amount = round(Amount)

Where the round() function rounds to the nearest integer. In most programming languages and spreadsheet applications, this function follows these rules:

• The decimal part is exactly 0.5, it rounds up to the next whole number.
• The decimal part is less than 0.5, it rounds down.
• The decimal part is greater than 0.5, it rounds up.

For the amount $67.89:

1. The decimal part (0.89) is greater than 0.5.
2. Therefore, we round up to the next whole dollar.

Rounded Amount = round(67.89) = $68

How do I round to the nearest dollar?

To round to the nearest dollar manually, follow these steps:

1. Look at the cents (the two digits after the decimal point).
2. If the cents are 50 or more, round up to the next dollar.
3. If the cents are less than 50, keep the dollar amount the same and drop the cents.

Let’s walk through an example with the amount $123.67:

The cents are 67.

Since 67 is greater than 50, we round up.

The rounded amount is $124.
