“YTD” gets used for at least three different calculations. The YTD calculator handles all of them, but knowing which one you are looking at is what stops the numbers being misread.

The three questions

YTD price return — how far the market value moved.

((Current Value − Start-of-Year Value) ÷ Start-of-Year Value) × 100

YTD total return — how far the value moved, plus what was paid out to you.

((Current Value + Dividends − Start-of-Year Value) ÷ Start-of-Year Value) × 100

YTD earnings — a running sum of pay received since January 1. A dollar amount, not a percentage.

The first two answer “how did this investment do?” and disagree with each other. The third answers a completely different question. The gap between price and total return is the subject of comparing your YTD return to a benchmark, where mixing them reverses conclusions.

Definitions

Start-of-year value. The prior December 31 closing value — equivalently, the value at the first trading day of January, since markets are shut over the New Year. Not the price you paid, and not the value on some other date you happen to remember.

Dividends and distributions. Cash paid out to holders during the period. Stocks and ETFs pay dividends; funds and REITs pay distributions. Either way, total return adds them back before dividing.

Rate of return. Gain or loss expressed as a percentage of what was invested. Every percentage figure here is a rate of return over a partial year.

Annualized projection. A full-year estimate extrapolated from a partial year:

Days-elapsed:    YTD Total ÷ Days Elapsed × 365   (366 in a leap year)
Pay-frequency:   (YTD Total ÷ Periods Received) × Periods per Year

This is a forecast built from a YTD figure, not a YTD figure. It assumes the rest of the year resembles the part so far — which is exactly the assumption seasonal or commission income breaks, covered in tracking YTD income with irregular pay.

Gross vs net. A YTD earnings total is gross pay as entered. Withholding, retirement contributions and other deductions are not subtracted.

Pay periods per year

Bi-weekly (every two weeks) and semi-monthly (twice a month) are not the same thing, and confusing them changes an annualized projection by roughly 8%.

Terms this calculator does not use

Time-weighted return (TWR). Strips out the effect of money moving in and out, so the figure reflects investment performance rather than the timing of your deposits. What fund managers are measured on.

Money-weighted return (MWR), or IRR. Includes the effect of your contribution timing. What you personally experienced.

The simple YTD formula is neither. It works when nothing was added or withdrawn during the year — and misreports badly when something was. How badly is worked through in why deposits break your YTD return calculation: a mid-year deposit can turn a genuine 7% into a reported 28%.

Modified Dietz. A practical approximation of time-weighted return that weights each cash flow by the fraction of the period it was invested. Close enough for most personal use, and much simpler than full daily valuation.

Which number to use when

If you only remember one thing: an index quoted in the press is almost always price return, and a fund fact sheet is almost always total return. Comparing the two directly flatters whichever side includes its dividends.
