Finance Calculators

To calculate your freelance hourly rate, start with your target annual take-home income and add self-employment tax (roughly 15.3% on net earnings), health insurance, retirement contributions, and business expenses. Divide that total by your realistic billable hours, which for most freelancers is 900 to 1,300 hours per year rather than 2,080. Adding a 20 to 25% overhead multiplier accounts for non-billable admin time, client acquisition, and gaps between projects. Use the freelance rate calculator above to run this math with your specific numbers.

PITI stands for Principal, Interest, Taxes, and Insurance. It represents your full monthly mortgage payment obligation rather than just the loan payment. Principal and interest cover the loan repayment. Property taxes are collected monthly and held in escrow by the lender. Homeowners insurance is also usually escrowed. If your down payment is below 20%, PMI (private mortgage insurance) is added on top. PITI is typically 20 to 30% higher than the principal-and-interest figure lenders quote in advertisements.

The debt snowball method pays off debts from smallest balance to largest, delivering quick wins that build motivation. The debt avalanche method pays off debts from highest interest rate to lowest, minimizing total interest paid. The avalanche method almost always saves more money in total interest. The snowball method can be more effective for people who need early psychological wins to stay on track. The debt snowball calculator above shows the exact difference in total interest and payoff timeline for your specific debts.

Most financial advisors recommend 3 to 6 months of essential living expenses in your emergency fund. Essential expenses include rent or mortgage, utilities, groceries, insurance premiums, minimum debt payments, and transportation. Freelancers, self-employed workers, single-income households, and anyone with dependents should aim for 6 months minimum. The emergency fund calculator above personalizes the recommendation based on your job security, income type, and monthly expenses.

The Rule of 72 is a mental math shortcut for estimating how long it takes money to double at a given interest rate. Divide 72 by the annual return to get the approximate years to double. At 6% annual return, money doubles in roughly 12 years (72 divided by 6 equals 12). At 8%, it doubles in 9 years. At 4%, it doubles in 18 years. The rule is slightly less accurate at very high rates but works well for typical savings and investment return ranges.

Net worth is the total value of everything you own minus everything you owe. Assets include cash, checking and savings balances, investment accounts, real estate, vehicles, and valuable personal property. Liabilities include mortgages, car loans, student loans, credit card balances, and any other debts. Subtract total liabilities from total assets to get your net worth. Tracking net worth over time is more meaningful than income alone because it reflects actual wealth accumulation and financial progress.

Divide the annual salary by the number of working hours per year to get the gross hourly rate. The standard calculation uses 2,080 hours (52 weeks at 40 hours). A $60,000 salary equals approximately $28.85 per hour. This gross figure does not account for taxes or benefits. To compare a salaried offer to freelance work, factor in the value of employer-provided health insurance, retirement contributions, and paid time off, which typically add 20 to 30% to total compensation value.

Inflation reduces the real purchasing power of savings over time. If your savings account earns 1% annual interest while inflation runs at 3%, your purchasing power decreases by approximately 2% per year. Over 20 years, this compounds significantly. A $50,000 balance growing at 1% while 3% inflation runs would have roughly $61,000 in nominal terms but only about $38,000 in real purchasing power. This is why financial planners recommend investing surplus savings in assets that historically outpace inflation.
