📘 For learning purposes only — these calculators use standard financial formulas to show how the math works, but they aren't personalized financial advice. Real budgets, savings accounts, and loans involve fees, taxes, and terms that vary by provider — always read the fine print or talk to a trusted adult / financial professional before making real financial decisions.
