The lessons teach the concepts. These four tools let you run your own numbers: no sign-up, nothing stored, just answers.
Each calculator pairs with a track: Savings Goal with Saving, Compound Interest and Loan Payoff with Interest and Debt, Inflation Impact with Inflation.
Planning rent, a laptop, or japa savings? Enter your target and what you can put aside monthly, and see exactly how many months it takes. Add an interest rate if the money sits in a locked plan, interest shortens the wait.
This is the "interest earning interest" effect from the Interest track, in action. Watch how a starting amount plus steady monthly contributions snowballs over years. Try 5 vs 15 years and see why starting early beats starting big.
Cash sitting idle quietly loses buying power every year. Enter an amount and today's inflation rate to see what it will really be worth in a few years. Fair warning: this one stings, and it is meant to.
Before taking any loan, or while repaying one, see the true picture: how many months it takes to clear at your payment level, and the total interest you will hand over. Try increasing the monthly payment and watch the interest cost drop.
