Finance Calculators

Our finance calculators help you make informed decisions about loans, investments, savings, and salary planning. Whether you are buying a home, financing a car, planning for retirement, or negotiating a salary, these tools give you clear answers without the complexity of spreadsheet models.

Loan Calculators

Understanding the true cost of borrowing is essential for financial health. Our loan calculators cover every major scenario: - Loan Calculator: compute monthly payments, total interest, and total cost for amortized, deferred, and bond loans - Auto Loan Calculator: factor in down payment, trade-in value, sales tax, and registration fees - Payment Calculator: determine monthly payment or time needed to pay off a loan - Amortization Calculator: generate complete amortization schedules with extra payment support - Interest Rate Calculator: find the effective interest rate given loan amount, term, and monthly payment

Example: A buyer looking at a $350,000 mortgage at 5.5% over 30 years enters the numbers and sees a monthly payment of $1,987, total interest of $365,000, and a complete amortization table showing principal vs. interest over time.

Investment & Savings Tools

Plan your financial future with confidence: - Investment Calculator: solve for any variable — end amount, contribution, return rate, or duration - Interest Calculator: project compound interest growth with contributions, tax adjustments, and inflation - Compound Interest Calculator: compare APY across different compounding frequencies

Example: A 30-year-old starts saving $500/month earning 7% annual return. The calculator projects over $610,000 by age 65. Adjusting to $750/month shows over $915,000 — a clear demonstration of the power of consistent saving.

Salary Converter

Whether you are comparing job offers, negotiating a raise, or budgeting as a freelancer, our Salary Converter converts between hourly, daily, weekly, monthly, and annual figures. Adjust for paid time off to see accurate comparisons.

Example: A contractor offered $75/hour wants to compare with a $140,000 salary. The converter shows $75/hour equals about $156,000 annually (assuming 40 hours/week, 52 weeks), helping them evaluate which option is better.
