How to Calculate Your Freelance Pay Rate (Beginner Guide)
To calculate your freelance pay rate as a beginner, add your desired annual income to your business expenses, then divide by your realistic billable hours per year — not the total hours in a work year. Most new freelancers can only bill 1,000–1,400 hours annually once admin, marketing, and unpaid time are factored in, so the resulting hourly rate is almost always higher than an equivalent salaried wage.

Loan amortization is the process of paying off a loan through fixed regular payments, where each payment covers that period's interest first and puts the rest toward the principal. Early payments are mostly interest; later payments are mostly principal.
