This free calculator shows how many hours your recurring admin chores take each month and what that time is worth in dollars. It is built for small-business owners who handle their own bookkeeping, invoices, and filing without dedicated back-office staff.
Free version: it runs in your browser — nothing you type leaves your device.
How to use the free calculator
- Enter the hours per week you spend on recurring admin tasks such as bookkeeping, invoices, and filing.
- Enter your average hourly value for that work, in dollars.
- Set how many weeks per month you want to count.
- Set the share of that time you think you could systematize, as a percentage.
- Read the monthly hours and dollar cost, then copy or print the result.
How the calculation works
The calculator multiplies your weekly admin hours by the number of weeks you count per month to get monthly hours. It then multiplies that by your hourly value to get the monthly dollar cost of the work. Finally, it applies the share you could systematize to show the hours and dollars that share represents.
In plain words: monthly hours = weekly hours x weeks per month. Monthly cost = monthly hours x hourly value. Freed-up hours = monthly hours x share systematized. Freed-up cost = monthly cost x share systematized.
Worked example with round numbers: 5 hours per week, 4 weeks per month, and a value of 30 dollars per hour gives 20 hours per month and 600 dollars in time value. If you could systematize 50 percent of it, that is about 10 hours and 300 dollars per month.
Common mistakes: counting only the big tasks and forgetting small recurring chores, using a wage figure that does not reflect what your own hour is worth to the business, and setting the systematize share at 100 percent when some tasks will always need a person. Treat every result as an estimate, not a precise accounting figure.
Frequently asked questions
How do I calculate the monthly cost of admin work?
Multiply your weekly admin hours by the weeks you count per month, then multiply by your hourly value. The calculator does this for you and also shows the effect of systematizing part of that time.
What hourly value should I enter?
Use a figure that reflects what an hour of your working time is worth to the business, such as what you would pay someone to do the same tasks. The result is only as realistic as the number you enter.
What does the systematize share mean?
It is the portion of your recurring admin time you believe could be handled by a defined routine, template, or schedule instead of ad hoc work. A share between 0 and 100 percent is accepted.
Does the calculator store my numbers?
No. It runs in your browser and works offline, so nothing is sent anywhere. You can copy or print the result if you want to keep it.
Is this a substitute for bookkeeping advice?
No. It is an educational tool that produces estimates. For tax, legal, or accounting decisions, consult a qualified professional.
