Investing
SIP Calculator
Project what a monthly SIP could grow to over time, and see how much of the total is your own contribution versus assumed returns.
Lumpsum Calculator
See how a one-time investment could grow at an assumed annual rate, and compare it against investing the same amount monthly.
Step-Up SIP Calculator
Model a SIP that increases every year, which is what usually happens as income grows, and see the difference against a flat SIP.
CAGR Calculator
Work out the compound annual growth rate between a starting value and an ending value over a given period.
XIRR Calculator
Calculate the annualised return on irregular cashflows — the right measure when money went in and out on different dates.
Compound Interest Calculator
See how compounding frequency and time change an outcome, and why the last few years contribute the most.
FD Calculator
Work out what a fixed deposit pays at maturity, and see how much more you get by reinvesting the interest instead of having it paid out.
RD Calculator
Calculate the maturity value of a recurring deposit, compounded quarterly the way banks do it, and see why the interest is smaller than it sounds.
Loans
EMI Calculator
Calculate the monthly instalment on a loan, with a full amortisation schedule showing how much of each payment is interest.
Valuation
DCF Calculator
Discount projected future cashflows back to a present value — the core of intrinsic valuation, with its assumptions made explicit.
Planning
