HTD (Half Year to Date)

Amazon & D2C glossary · Harpy Media

HTD (Half Year to Date) measures cumulative performance from the start of a six-month period to today — so mid-March’s HTD is everything since January 1; mid-October’s is everything since July 1. It’s the medium-sized lens between monthly noise and annual hindsight.

What is HTD?

HTD (Half Year to Date) measures cumulative performance from the start of a six-month period to today — so mid-March’s HTD is everything since January 1; mid-October’s is everything since July 1. It’s the medium-sized lens between monthly noise and annual hindsight.

On Amazon, HTD earns its keep as a trajectory instrument: monthly numbers are too jumpy to steer by, annual numbers arrive too late to change anything — but half-year cumulative totals against the same point in prior periods show whether the business is genuinely on plan while there’s still most of a season left to act.

What HTD reveals that other lenses miss

Three uses. Trajectory detection: comparing HTD this year against HTD last year (same calendar points) strips out month-to-month variance and shows net direction — is the growth real or was it one good month? Budget anchoring: mid-year reviews against HTD-to-target tell you whether the second half needs course-correction while course-correcting is still cheap. Seasonal honesty for Amazon: because cash and demand are so seasonal (H2 carries the revenue weight, H1 carries the reset), raw cumulative totals can mislead if read without context — the professional read compares like windows to like windows (HTD January–June against January–June), never a half against a different half.

Running the review (so it pays)

The rhythm: at each half-year midpoint (end of June, end of December), assemble the standard pack — HTD revenue and units against plan and against prior-year HTD, HTD contribution margin (not just revenue), advertising efficiency (TACoS HTD), inventory health (aging buckets, DIO), and cash position. Then the decision layer, which is what separates a report from a review: two or three named adjustments for the coming half — each with an owner and a number attached (“cut TACoS on line B to X by September”) — and a stated check-in date. The habit that compounds: keep the prior reviews on file and open each new one by scoring the last — the accountability loop is the whole value, because HTD’s superpower isn’t the number, it’s arriving early enough to matter.

HTD = cumulative metric from period start (Jan 1 or Jul 1) to today  ·  compare like-window to like-window — never half against halfMid-point reviews are cheap course corrections; year-end reviews are autopsies.

In practice

A brand’s June HTD review shows revenue essentially flat against last year — but underneath: contribution margin down two points (freight increases absorbed, not passed through), and subscription revenue up sharply. The adjustments the meeting names: a targeted repricing of three SKUs to restore contribution, and a redirection of launch budget toward the subscription line that’s pulling ahead of plan. By December, HTD revenue is +9% with margin recovered — because the halfway review had converted a soft-looking story into two actionable numbers while the back half was still unspent.

⚠️ Watch out. A seller does annual reviews — and by February, when the real numbers land, every fix is retrospective. The stock that didn’t sell was ordered in August; the margin drift started in April. The information to act arrived in January; January had nothing left to act on.
💡 Harpy tip. Put two dates in the calendar now: end of June and end of December. Ninety minutes, the standard pack, and two named adjustments. The discipline is the entire ROI.

How Harpy Media helps

Half-year checkpoints with scored actions are part of our client rhythm — mid-year is when the second half is still shaped like a plan instead of a post-mortem.

HTD FAQ

What is HTD?

Half Year to Date — cumulative performance since the start of a six-month period (January or July) up to the current date.

How is HTD different from YTD?

YTD accumulates from the year’s start; HTD from the start of the current half — a medium lens between monthly noise and annual totals.

Why review at HTD midpoints?

Because halfway through a half, corrective action is still cheap: budget, pricing, and inventory decisions made then shape the remaining months; made at year-end they shape nothing.
