Compound interest methodology
Compound growth applies interest to principal and previously credited interest. The periodic rate and number of periods must use the same frequency. A nominal annual rate compounded monthly is not entered in exactly the same way as an effective annual rate.
Contributions and timing
Recurring deposits made at the beginning of a period receive one additional period of growth compared with end-of-period deposits. Fees, taxes, withdrawals and variable rates are outside a simple fixed-rate projection unless explicitly included.
Use CAGR to annualise growth between two values, or XIRR for irregular dated cash flows.
