% of Prime-promise (1-day / 2-day) shipments delivered late. Amazon’s SFP eligibility hinges on this; >1% triggers warning.

At a glance

Inverse of amazon_prime_sfp_otd_sla on a 7-day window: percent of Prime-promised (1-Day or 2-Day) shipments delivered late. Used as a fast-cadence early-warning. The 7-day window is what Amazon often uses internally for trending; this card lets ops act before the 30-day SFP eligibility card slips. Above 1% = within Amazon’s SFP-warning trigger zone.

Calculation

Calculated automatically from your Amazon Prime Shipping (SFP) data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A US merchant on SFP. Reading at 09:00 ET on 18 Mar 26 for the trailing 7 days (11 Mar 26 to 17 Mar 26).
MetricValue
Prime-promised shipments (7D)1,725
Delivered on time1,691
Missed34
Promise miss rate2.0%
The card reads 2.0%, double the 1% alert and well above the SFP eligibility threshold (1% miss = 99% on-time = the Amazon-published floor). Five things to notice:
  1. Tripped at 2.0% means 2 of every 100 Prime customers got a broken promise. This week is materially below the Prime-badge floor.
  2. At sustained 2.0%, the 30-day SFP card will trip in ~3 weeks if the trend continues. Amazon’s warning notification often arrives ~7 days after a sustained 2%+ pattern. Treat this card as the leading indicator that buys you 1 to 2 weeks before the existential SFP card alerts.
  3. 34 misses × 5to5 to 10 Amazon Concession cost = ~170to170 to 340 of Concession charges this week alone. That is direct out-of-pocket cost to the seller as Amazon credits Prime customers.
  4. Investigate by carrier and ZIP via ama_route_otd. Almost always one or two underperforming cohorts (USPS Priority rural, OnTrac specific zone) account for >50% of weekly misses.
  5. Compare against last week. If 7-day miss rate jumped from 1.2% to 2.0% week-on-week, the 67% rise is the pattern signal. Most likely cause: volume rise straining a carrier’s pickup capacity, weather event in the period, or a packaging change creating damage exceptions.

Known limitations / merchant FAQs

Why 7 days when SFP eligibility is 30 days? Speed. The 30-day card lags by definition; you cannot intervene until you can see the trend forming. The 7-day window is what most ops teams use for daily standup-and-action; the card alerts you 1 to 2 weeks before the 30-day SFP card slips below 99%. Above 1% is “warning”; what is “critical”? The card uses a single >1% threshold. In Amazon’s eligibility scoring, the practical critical threshold is sustained 2.5%+ over 30 days; that is when badge revocation begins. The 7-day card surfaces well before that. Treat 1.5% as the conversation, 2.5% as the emergency. A single bad day pushes us above 1%; should we react? Investigate but do not over-react. Single-day spikes happen for legitimate reasons (weather, depot strike, holiday-adjacent volume crunches). Look at the 7-day window context: is this single day or sustained 3+ days? Sustained patterns are real signals; single days are noise to investigate but not panic over. Concession cost vs lost revenue: which dominates? At 1 to 2% miss rate the Concession cost dominates (5to5 to 10 × misses = direct out-of-pocket). At sustained 2.5%+ the eligibility risk dominates: badge loss = 30 to 50% Buy Box drop = revenue impact dwarfs Concession cost. Can we exclude weather days? File Seller Central case for weather events. Card includes all unless tagged. Multi-warehouse SFP: this card pools all? Yes. The card aggregates across all SFP-connected warehouses. Per-warehouse view requires per-warehouse filter; available in ama_route_otd. Buy with Prime: same threshold? Yes 1% miss rate triggers warning. Buy with Prime program team monitors with similar cadence to Amazon SFP. Q4 peak realistic miss rate? 2 to 4%. Most SFP merchants run 0.8 to 1.5% steady-state and 2.5 to 4% Q4 peak. Pre-plan: aggressive ZIP opt-outs in October, capacity-locked carrier agreements, possible seasonal SFP suspension. The card flags but the SFP card is in spec; trust this one? Yes. This card is the leading indicator. SFP card lags by 30-day window. When this card sustains above 1% for 3+ weeks the SFP card will dip below 99%; act on this card before that happens.
