Which Financial Calculator Should You Use?
Start with what you are trying to decide. If you are buying a home, use How Much House Can I Afford first — it shows your maximum price using the 28/36 debt-to-income rule before you start browsing listings. Then use the Mortgage Calculator for the specific property to see full amortization, total interest, and monthly PITI breakdown. If you already have a mortgage and are considering refinancing, the Refinance Breakeven Calculator finds the exact month your closing costs are recovered through lower payments.
Understanding Compound Growth
The Compound Interest Calculator is suitable for savings accounts and fixed-return instruments. The Investment Calculator adds inflation adjustment, annual fee drag, and capital gains tax drag to model a real investment portfolio more accurately. It also includes best/base/worst-case scenarios using ±3% around your base return rate, and solves for the required monthly contribution or required return to hit a savings goal.
Paycheck vs. Salary Calculations
The Salary to Hourly Calculator converts an annual salary to a true hourly equivalent, accounting for overtime, unpaid leave, and benefits value. The Paycheck Calculator goes further: it estimates your actual take-home pay by applying 2024 federal income tax brackets, state income tax flat rates, FICA (Social Security and Medicare), and any pre-tax or post-tax deductions you enter. Neither tool replaces your employer's payroll system, but both give you an educated estimate of what to expect.
Credit Card Payoff Strategies
The Credit Card Payoff Calculator compares five strategies — minimum payment, fixed payment, avalanche (highest interest first), snowball (lowest balance first), and a custom approach — with exact debt-free dates and total interest for each. For most people with multiple cards, the avalanche method saves the most money, while the snowball method can be more motivating. Seeing both numbers side by side makes the trade-off concrete.
