Glossary
APR (Annual Percentage Rate)
The yearly cost of borrowing, expressed as a percentage that includes interest plus certain required fees.Cost Basis
The total you paid for a holding, including commissions and fees, and the figure every gain or loss on it is measured against.Debt Avalanche
A payoff order that sends every extra dollar to the highest-interest debt first, minimizing total interest paid.Debt Snowball
A payoff order that targets the smallest balance first, trading some extra interest for an early, visible win.Emergency Fund
Cash set aside strictly for unplanned expenses, kept liquid and separate so a bad month does not become new debt.Envelope Budgeting
A budgeting method that assigns every dollar to a named category up front, so spending is checked against a plan rather than a balance.Expense Ratio
The annual percentage a fund charges to run itself, taken out of the fund's value rather than billed to you.Money-Weighted Return
The annualized rate your own contributions actually earned, counting when each one went in — the return you got, as distinct from the return the investment got.Net Worth
Everything you own minus everything you owe, measured on a fixed cadence so the trend rather than the number carries the information.Time-Weighted Return
The return an investment earned with the timing and size of deposits divided out — the figure that can fairly be compared against an index.Unrealized Gain
The difference between what a holding is worth today and what it cost, while you still own it and before any sale locks it in.Yield on Cost
The income a position paid over the last year measured against what you originally paid for it, rather than against what it is worth today.
