Loan & Mortgage Calculators
Our loan and mortgage calculators cover every scenario from basic monthly payment calculations to complex amortization schedules showing principal vs interest breakdown over time. Need to compare multiple loan offers side-by-side? Our loan comparison calculator shows total interest paid, monthly payments, and break-even points. Planning an early repayment strategy? Calculate exact savings from extra principal payments each month. Mortgage tools include refinancing analysis, balloon payment scenarios, and adjustable-rate mortgage projections—all using your specific rates and terms.
Business Pricing & Unit Economics
For entrepreneurs and e-commerce owners, our business calculators handle markup percentages, gross margin analysis, break-even points, and complete unit economics breakdowns. Enter your cost of goods, desired profit margins, and fixed overheads to instantly see optimal pricing strategies. The pricing calculator works backward from target margins to determine minimum selling prices, while cost breakdown tools separate fixed vs variable expenses for better profitability analysis.
Investing Math (No Market Data)
Pure compound interest calculations with flexible compounding frequencies (daily, monthly, quarterly), regular contribution scenarios, and future value projections.
