Each billable entry is rounded on its own, which is how most firms bill increments. Check your engagement letter for the rule you agreed.
How to calculate billable hours
Add each time entry in minutes and tick whether it’s billable.
Choose your billing increment. Law and accounting firms often bill in 6-minute units (0.1 hour); agencies often use 15 minutes.
Choose the rounding rule you agreed with the client: up, to the nearest increment, or down.
Enter your hourly rate to see the amount to bill.
The tool runs entirely in your browser. Nothing you type is sent to Angelwood or saved on a server.

Each billable entry is rounded on its own. Rounding a whole day’s total instead gives a different answer, so follow the rule in your engagement letter.
Worked example
A 7-minute call rounds up to 12 minutes (0.2 hours) and 50 minutes of drafting rounds up to 54 minutes (0.9 hours). That’s 1.1 billable hours; at £150 an hour, £165. Thirty minutes of internal admin isn’t billed.
