What can you do with these calculators?
The FD / Growth calculator turns interest, amount, and time into a clear maturity figure, while the Advanced calculator handles everything from quick arithmetic to trigonometry and logarithms.
Plan savings goals
Work backwards from a target — a house down-payment, a wedding, a car — and see how much a lump sum grows before you need it.
Fixed deposits & PPF
Model bank FDs, PPF, or any lump-sum instrument. The 6.8% default mirrors typical small-savings rates; adjust it to your bank’s offer.
Compare rate & tenure
Drag the sliders to instantly compare what a higher rate or a longer horizon does to your maturity value and total interest earned.
Understand compounding
Switch the compounding frequency to see why quarterly or monthly compounding beats annual — the year-by-year table makes it concrete.
Growth is compound interest:
A = P × (1 + r/n)n·t
where P is your amount, r the annual rate, n the compounding periods per year, and t the number of years.
A full expression calculator that evaluates as you type. It supports parentheses, powers, roots, factorials, π and e, trigonometry (with a DEG/RAD toggle), and natural & base-10 logarithms. Every result is kept in a reusable history, and your physical keyboard works too.
