Age Calculator
Age Calculator can accurately calculate your exact age based on your birthday. Years, months, and days will be presented as the determined age.
Stop guessing your freelance rate. Enter your income goal, billable hours, expenses, and overhead to see the exact hourly rate you need to charge.
An Hourly Rate Calculator works backwards from the income you want to the rate you actually need to charge for it.
Most freelancers guess a number and hope it adds up; this tool starts from your goal, your real billable hours, and your costs, then tells you the rate that makes the year work.
The classic mistake is taking a target salary and dividing by a full-time year of hours.
As a freelancer you do not bill every hour you work โ admin, sales, invoicing, and downtime all eat into the day โ and you carry business expenses an employer would normally cover.
This calculator accounts for both, so the rate it returns reflects the hours you can genuinely invoice.
First it adds your desired income to your annual business expenses to get the total you must bring in.
Then it multiplies your billable hours per week by your working weeks and trims that by your non-billable overhead to find your effective billable hours.
Dividing the total you must earn by those effective hours gives your rate, and you can sanity-check any ratio along the way with a Percentage Calculator.
The figure it returns is a floor that covers costs but adds no profit, so most freelancers mark it up.
A Gross Margin Calculator helps you layer a margin on top, and when you quote a client a Sales Tax Calculator makes it easy to add or separate any tax on the final invoice.
The tool adds your desired income and business expenses, then divides that total by your effective billable hours. Effective hours are your billable hours per week times your working weeks, reduced by the non-billable overhead percentage you enter.
It is the share of your working time you cannot invoice: marketing, admin, proposals, email, bookkeeping, and unpaid revisions. Setting it to 15 to 30 percent is common, and raising it pushes your rate up because fewer hours actually earn money.
Yes. The result covers income and expenses only, so it is a minimum rate. Add a margin for profit and set aside money for taxes separately, since the calculator does not deduct them.
No. Every calculation happens locally in your browser with JavaScript. Nothing you type is uploaded, logged, or stored, and the tool keeps working offline once the page has loaded.
