US Loan & Debt Calculators

Personal loans, auto loans, credit cards — US credit products use the same amortisation maths as everywhere else, but APRs vary enormously by lender type and credit score. Federal student loans use their own income-driven repayment formulas; private student loans behave like personal loans. The calculators in this hub run amortisation on any fixed-rate loan, compare offers like-for-like on APR (capturing fees as well as the headline rate), build a multi-balance debt-payoff plan via the snowball or avalanche method, and project the cost of carrying credit-card debt at typical 18–25% APRs versus an aggressive payoff schedule.
