Missed work
Hours that never make it into the final invoice.
Free calculator
How much revenue is leaking out of late logging and invoice cleanup?
If billing day still means remembering what happened, rebuilding line items, and chasing follow-up in separate places, this calculator shows the cost in dollars and hours.
Invoice reconstruction
Admin time spent rebuilding what the work already should have said.
Reminder drag
Follow-up and payment-checking time that stays scattered.
Calculator inputs
Run your real billing leak.
If you bill day rates or retainers, use your effective hourly rate.
$/hr
This estimate assumes 4.33 weeks per month and values lost admin time at your billable rate. It is directional by design: useful for sizing the leak, not for pretending your week is perfectly linear.
Where the leak usually starts
The missing money usually is not in one big miss. It is in the handoffs.
Most freelancers and consultants do not lose revenue because they forgot to work. They lose it because the record gets weaker as the week goes on.
Late logging
A half hour here and forty minutes there disappear when the timer is reconstructed later.
Missing context
You remember the time, but not always the exact client, task, or why the work mattered.
Invoice rebuilds
Billing becomes a second documentation job when the invoice does not start from the work record.
Scattered follow-up
Reminder timing, view status, and payment tracking get pushed into inboxes and notes instead of staying near the bill.
A cleaner path
The goal is not to obsess over time. It is to keep the billing trail intact.
1. Track it with context
Start from the client, project, and task you are actually working on so the session is usable later.
2. Review it before you bill
Use recent, track, and calendar views to catch weak spots before the invoice becomes client-facing.
3. Invoice from the record
Turn tracked work into the draft, then keep reminders and payment status attached after send.
FAQ
Questions people usually ask before they try it
What does this calculator count as forgotten revenue?
It estimates two things: billable work that slips through late logging and the value of time spent rebuilding invoices or chasing payment status later.
Why does it value admin time at my billable rate?
Because that time usually crowds out client work. It is a directional estimate, but it gives a more honest picture of the cost than treating cleanup work as free.
How does Clockout help reduce this leak?
Clockout keeps time tracking, review, invoice drafting, reminders, and payment status in one workflow so the record stays strong from live work to final invoice.
