Determine the exact hourly rate you need to charge to meet your income goals while covering business expenses and accounting for non-billable time.
Take-home pay you want *after* expenses (before taxes).
Software, hardware, insurance, accounting fees, etc.
Hours actually invoiced to clients (exclude admin/marketing).
Vacation, sick days, and holidays.
Why Generic Hourly Rates Fail Freelancers
One of the most common mistakes new freelancers make is setting their hourly rate based on their previous salary or vague industry averages. They often think, "I used to make $40 an hour at my job, so I'll charge $50 now." This approach almost always leads to undercharging and financial stress.
As an employee, your employer covers overhead costs like office space, software licenses, hardware, health insurance, and the employer half of self-employment taxes. Furthermore, as an employee, you are generally paid for every hour you are at work, whether you are actively coding/designing or sitting in a team meeting.
As a freelancer, you must cover all of these costs yourself. More importantly, you cannot bill for every hour you work. You have "non-billable" time spent on marketing, invoicing, answering emails, and learning new skills. If you don't factor this unbillable time into your rate, you will essentially be working those hours for free.
Understanding the Calculator Inputs
To calculate a sustainable rate, you need to work backward from your financial goals and realistic working capacity.
Desired Annual Net Income: This is the "take-home" pay you want *before* personal income taxes, but *after* business expenses. Think of this as your salary replacement goal.
Estimated Annual Business Expenses: Sum up everything you spend to run your business. This includes website hosting, subscriptions (Adobe CC, Jira, etc.), new laptops, accountant fees, professional liability insurance, and internet costs.
Realistic Billable Hours Per Week: Be honest here. You rarely bill 40 hours a week. A healthy freelance practice often only manages 25-35 billable hours weekly, with the remaining time dedicated to administration and business development.
Weeks Off Per Year: Freelancers need breaks too. Account for national holidays, planned vacations, and a buffer for sick days. If you don't plan for time off, you won't be able to afford to take it.
A Realistic Example
Let's look at a hypothetical freelance graphic designer named Alex.
Alex wants a desired net income of $80,000 per year.
They estimate their annual business expenses (software, new computer, home office portion) at $15,000.
They know they spend about 10 hours a week on admin, so they can realistically bill 30 hours per week.
They want to take 3 weeks of vacation plus 1 week for sick time/holidays, totaling 4 weeks off.
Using the calculator above, Alex needs to generate a total gross revenue of $95,000 ($80k + $15k). With 4 weeks off, they are working 48 weeks a year. At 30 billable hours per week, that's 1,440 total billable hours per year.
The calculation is: $95,000 total needed / 1,440 billable hours = $65.97 per hour.
This is Alex's minimum required rate just to hit their baseline goal. Most experts recommend adding a profit margin on top of this base rate so the business can grow.

Understanding Mortgage Affordability
Determining how much house you can afford is a crucial step in the home-buying process. A mortgage affordability calculator helps you estimate the maximum home price you can realistically purchase based on your financial situation. It takes into account your income, existing debts, down payment, and the estimated terms of the loan.
Key Factors in Mortgage Affordability
Annual Gross Income: This is your total income before taxes and other deductions. Lenders use this as a primary indicator of your ability to repay a loan.
Monthly Debt Payments: This includes payments for other loans such as car loans, student loans, and credit card minimum payments. Lenders sum these up to understand your existing financial obligations.
Down Payment: The amount of cash you pay upfront towards the purchase price of the home. A larger down payment reduces the loan amount needed and can improve your chances of approval and secure better loan terms.
Interest Rate: The annual interest rate charged by the lender on the loan. This significantly impacts your monthly payment and the total cost of the loan over time.
Loan Term: The number of years you have to repay the mortgage (commonly 15 or 30 years). A shorter term means higher monthly payments but less interest paid overall, while a longer term means lower monthly payments but more interest paid.
How Affordability is Calculated (The 28/36 Rule)
A common guideline used by lenders is the 28/36 rule:
28% Rule (Front-End Ratio): Your total monthly housing expenses (including Principal, Interest, Property Taxes, and Homeowner's Insurance – often referred to as PITI) should not exceed 28% of your gross monthly income.
36% Rule (Back-End Ratio): Your total monthly debt obligations (including PITI and all other recurring debts like car payments, student loans, and credit card payments) should not exceed 36% of your gross monthly income.
Our calculator uses these principles to estimate your maximum affordable monthly payment and, subsequently, the maximum loan amount and home price you can consider. It's important to remember that these are general guidelines. Lenders will also consider your credit score, employment history, assets, and other financial factors. Property taxes and homeowner's insurance, which vary by location and the specific property, are estimated in the PITI calculation and can significantly affect your actual monthly payment.
Maximum Affordable Monthly Housing Payment (28% of $7,500) = $2,100
Maximum Total Monthly Debt Obligations (36% of $7,500) = $2,700
Remaining for Housing Payment after other debts ($2,700 - $600) = $2,100
The affordable monthly payment is capped at $2,100.
Using the mortgage payment formula, a $2,100 monthly payment at 7.0% interest over 30 years supports a loan amount of approximately $314,000.
Estimated Maximum Home Purchase Price = $314,000 (Loan Amount) + $30,000 (Down Payment) = $344,000
This example suggests that with these financial details, a person could potentially afford a home priced around $344,000, assuming the monthly PITI does not exceed $2,100.
