About Our Calculators

Every calculator on LifeStarter is free, requires no account signup, and is designed to give you a realistic picture of your financial situation. We use conservative estimates and current data to ensure results are meaningful — not optimistic projections that set you up for a surprise.

Mortgage Affordability Calculator

Most banks will approve you for far more than you should actually spend. Our mortgage calculator helps you find a payment that fits your lifestyle, not just your maximum debt-to-income ratio. Enter your gross income, existing debts, and down payment to see a realistic purchase price range.

Emergency Fund Calculator

The standard advice is "save 3-6 months of expenses," but the right number depends on your job stability, family size, and risk tolerance. Our calculator gives you a personalized target and shows how long it will take to get there based on your current savings rate.

Student Loan Payoff Calculator

See exactly when you'll be debt-free and how much interest you'll pay in total. More importantly, see how adding even $50-$100 extra per month can shave years off your payoff timeline and save thousands in interest.

Buy vs. Lease Car Calculator

The lease vs. buy decision is more nuanced than most people think. It depends on how much you drive, how long you keep cars, and what you do with cash flow. Our calculator shows the true total cost of each option over your ownership horizon.

All calculations are estimates for planning purposes. Consult a qualified financial advisor for personalized advice.
