Calculators built to teach the formula, not hide it
Each tool shows the equation it uses and explains how to interpret the answer. Change one input at a time and watch which variable actually matters.
These calculators are learning aids. Assumed rates are hypothetical inputs chosen by you, not expected or promised returns.
CAGR Calculator
CAGR = (Final / Initial)^(1/n) − 1
CAGR smooths an actual, uneven journey into one constant annual rate. It tells you the average pace, never the path — a 15% CAGR can hide a 40% drawdown along the way.
SIP Calculator
FV = P × [((1+r)^n − 1) / r] × (1+r)
Assumes a constant monthly contribution and a constant assumed return. Real markets deliver neither, so treat the output as a planning illustration and not a forecast of returns.
Risk / Reward Calculator
R:R = (Target − Entry) / (Entry − Stop)
The break-even hit rate is the win percentage needed just to avoid losing money at this ratio, before costs and taxes. It is why a 1:3 setup tolerates being wrong most of the time.
Position Size Calculator
Qty = (Capital × Risk%) / (Entry − Stop)
Size is an output of your risk rule, never an input based on conviction. Note how a tighter stop allows more quantity for the same rupee risk — and also gets hit more often.
P/E Valuation Learning Calculator
P/E = Price / EPS • PEG = P/E / Growth%
A P/E is only meaningful against peers and against growth. PEG is a rough sanity check, not a valuation method — it assumes growth is durable and comparable, which it often is not.
Compound Interest Calculator
A = P × (1 + r/f)^(f × n)
Increase the years input and watch the curve steepen late — most of compounding's visible effect arrives at the end, which is exactly when people tend to interrupt it.
