The running total is the easy part. Where irregular income breaks the tool is the projection — because annualizing assumes a flat year, and a flat year is precisely what freelance, commission and seasonal work is not.

The projection is arithmetic, not a forecast

You have earned $9,600 by April 15 — day 105 of the year. The days-elapsed method gives:

$9,600 ÷ 105 × 365 = $33,371

That is not a prediction. It is the answer to “what would a perfectly even year look like from here?” Now put shape on it:

A 2× spread from the same YTD figure. The projection is not wrong — it is answering a different question from the one you meant.

When each method applies

Days-elapsed works for any income pattern, because it only needs a date. Use it for freelance, commission and mixed income.

Pay-frequency — dividing by periods received and multiplying by periods per year — is more accurate for a fixed salary, since it is unaffected by where pay dates fall in the calendar. It requires a fixed schedule, so it does not apply to irregular work at all.

Both are available in the YTD calculator, and the terms reference has the pay-period counts if you are on a salary.

Better tools for a lumpy year

Compare to the same point last year. If you were at $9,600 by mid-April last year and finished at $28,000, that ratio is a far better guide than a straight line. It has your seasonality baked in.

Use a rolling twelve months. Total the last twelve months rather than the calendar year to date. It always contains one full seasonal cycle, so it does not lurch every January.

Project by known work, not by pace. Contracted work plus a realistic estimate of what is likely to close beats extrapolating from a partial year.

Track a floor and a ceiling. Instead of one projected number, keep a pessimistic and an optimistic figure. That is an honest representation of what you actually know.

Why this matters beyond curiosity

Irregular income usually means quarterly estimated tax payments, and those are sized from an expected annual figure. Overestimate and you hand over cash you needed for working capital; underestimate and you can face an underpayment penalty. The IRS publishes the rules and safe-harbour provisions for estimated taxes, and they are worth reading once rather than guessing.

The practical consequence: if a straight-line projection is driving your tax set-aside, and your income is seasonal, the set-aside is wrong in a predictable direction. Front-loaded earners over-reserve early and under-reserve late; back-loaded earners do the reverse and are the ones who get caught.

A workable routine

1. Log every payment as it lands. The running total is the part that is always accurate.
2. Check the projection monthly, not daily. It swings hard early in the year when the denominator is small — in January a single invoice can move it by thousands.
3. Compare against the same date last year as the primary sanity check.
4. Keep the set-aside percentage fixed, based on the annual figure you actually expect, not the projected one.
5. Re-forecast quarterly with what you now know about the pipeline.

The running total is a fact and the projection is a hypothesis. Treating the second as reliably as the first is one of the errors in 6 YTD mistakes that distort your numbers — and on irregular income it is the most expensive one.
