Investing
Project growth, understand returns, and get the mechanics of compounding straight.
Compound Interest & Future Value
Project how a lump sum and monthly contributions grow over time.
Present Value
What a future amount of money is worth today, discounted back by a rate of return.
CAGR
The single steady annual growth rate that would take a starting value to an ending value over a period.
Intrinsic Value (DCF)
A two-stage discounted cash flow estimate of what an investment is actually worth, based on projected future cash flows.
Real Return
Your investment return after subtracting inflation, what your money actually gained in purchasing power.
Rule of 72
A quick mental-math estimate for how many years an investment takes to double.
Dollar-Cost Averaging
Investing a fixed amount on a regular schedule, regardless of price, to smooth out market timing.
PnL Multiplier
Turn a profit/loss percentage into the "times your money" multiple — 100% gain is 2x, a 50% loss is 0.5x.
