# Use exact times in SLA calculations

# Use exact times in SLA calculations {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
When business percentages are used for SLA calculations, they are rounded up to two
decimal places.

## Before you begin

Role required: admin

## About this task

As a result, breaches can occur when SLA calculations are rounded up to 100%. You can enable SLA calculations to instead use the business time or actual time left.

For
example, a business percentage of 99.951% is rounded up to 100%, which causes a
breach.

For more accurate SLA calculations, enable the SLA engine property for
using the exact value of the business time left if a schedule is specified or the
actual time left if the SLA has no schedule specified.

## Procedure

1. Go to Service Level ManagementPropertiesSLA Engine.
2. For the Use field "business_time_left" to calculate breach time instead of "business_percentage" field property, select the Yes check box.
3. Click Save.
