Finance Tools

Money decisions are decided by arithmetic that is easy to get wrong in your head: what a mortgage actually costs over twenty-five years, how much of an early loan payment is interest, what a monthly investment becomes at compound growth. The seven calculators here run the numbers precisely, show the breakdown, and never send a figure anywhere — every calculation happens in your browser.

Mortgage Calculator breaks a home loan into principal and interest per period and shows the total cost over the term — the tool for comparing a 20-year against a 30-year loan, or the effect of a rate change. Loan Calculator does the same for personal and car loans, and makes the true cost of long tenors visible. Installment Calculator handles buy-now-pay-later and installment plans, showing the effective burden per month.

Growth and returns: Compound Interest Calculator projects savings with regular contributions — the clearest demonstration of why starting early beats starting big. Investment Return Calculator computes total and annualized returns so you can compare investments honestly across different holding periods.

Daily money: Tax Calculator estimates income tax from brackets so a salary offer can be compared after tax, and Tip Calculator splits restaurant bills and tips across any number of people without mental math.

How to choose: match the calculator to the decision — comparing loan offers needs the loan calculator's total-interest view, not the monthly payment alone; deciding whether to invest a lump sum or monthly needs the compound view. Practical tips: change one variable at a time so you know what caused the difference; remember calculators show estimates — taxes and fees vary by jurisdiction; and for big decisions, bring the printed breakdown to a professional advisor rather than a single number.
