How good was your investment really — regardless of timing?

TTWROR (True Time-Weighted Rate of Return) measures how well an investment has performed, independent of when and how much you deposited or withdrew. The timeline is split into periods at each cash flow, and the individual period returns are then chain-linked.

Many apps only show the simple difference between what you paid in and your current portfolio value. That naive figure is distorted by the timing of your deposits — a sum paid in shortly before a price rise makes it look too good. TTWROR backs that effect out.

TTWROR judges the quality of the investment itself, independent of deposit timing — the right figure for comparing against a benchmark index. XIRR judges your personal result including your timing on deposits and withdrawals. Both numbers are correct — they just answer different questions. You can work out the money-weighted figure in the XIRR calculator.

A new period starts at every deposit or withdrawal. A period's end value is the portfolio value right before the next cash flow, and the following period's start value is that same figure — the cash flow itself goes into the deposit or withdrawal field of the new period.

Yes. After importing your portfolio via CSV, PDF or automatic sync, Planafolio calculates TTWROR directly from your actual transactions — no need to enter periods by hand.
