Rounding options

When you configure a percent tax rate, you select a rounding option for the tax rate. A rounding option determines how tax amounts that have three or more decimal places are rounded to two decimal places. This type of rounding is often called penny rounding, because each fractional penny is rounded to a whole penny.

For example, a tax rate of 6.25%, when applied to a $50.75 check, results in a tax amount of $3.171875. Depending on which rounding option you select, the sales tax would be rounded down to $3.17 or rounded up to $3.18.

Note

If you also create a takeout tax rate, the rounding option applies to both the basic percent tax rate and the secondary takeout tax rate.

The following table describes the four Toast rounding options.

Rounding Option Rounding Behavior Rounding Examples

Half Even Rounding

Except for half-way values, always round fractional pennies to the nearest whole number (either up or down). For example, $1.234 rounds down to $1.23 and $1.236 rounds up to $1.24.

For half-way values (where the number-to-round is exactly between two numbers, such as the 5 in $1.235), round to the nearest even number. For example, $1.235 rounds to $1.24.

$0.112 -> $0.11

$0.115 -> $0.12

$0.125 -> $0.12

$0.135 -> $0.14

Half Up Rounding

Except for half-way values, always round fractional pennies to the nearest number (either up or down). For example, $1.234 rounds down to $1.23 and $1.236 rounds up to $1.24.

For half-way values (where the number-to-round is exactly between two numbers, such as the 5 in 1.235), always round up. For example, $1.235 rounds up to $1.24 and $1.345 rounds up to $1.35.

$0.112 -> $0.11

$0.115 -> $0.12

$0.125 -> $0.13

$0.135 -> $0.14

Always Round Down

Always round down every fractional penny, including half-way values.

For example, $1.234, $1.235, and $1.236 all round down to $1.23.

$0.112 -> $0.11

$0.115 -> $0.11

$0.125 -> $0.12

$0.135 -> $0.13

Always Round Up

Always round up every fractional penny, including half-way values.

For example, $1.234, $1.235, and $1.236 all round up to 1.24.

$0.112 -> $0.12

$0.115 -> $0.12

$0.125 -> $0.13

$0.135 -> $0.14
