What is UPS’s on-time delivery rate for ground shipments? (2025 data)
UPS Ground achieved a 96.5% on-time delivery rate in December 2024, according to ShipMatrix’s independent audit—marking the seventh consecutive year UPS led the industry during peak season. This performance represents a slight decline from UPS’s 2023 rate of 98.7% but still positions UPS Ground as the most reliable ground shipping service, outperforming both FedEx Ground (91.8%) and USPS Ground Advantage (90.4%) during the same period.
Understanding how carriers measure and report on-time delivery helps merchants make informed shipping decisions and set realistic customer expectations.

Why on-time performance matters
Late deliveries directly impact customer satisfaction and repeat purchase rates. Studies show that 69% of consumers are less likely to shop with a retailer again after a poor delivery experience, while 38% will abandon their cart if delivery options don’t meet expectations.
For merchants, missed delivery promises create a cascade of operational costs: customer service inquiries increase by 40%, return rates climb, and negative reviews accumulate. Understanding carrier reliability helps businesses set accurate delivery expectations and choose the right shipping mix.
How UPS defines “on-time”
UPS measures on-time delivery against the committed delivery date shown at checkout and on tracking pages. For UPS Ground, this calculation follows specific business-day logic that excludes weekends and holidays from transit time.
Business-day vs. calendar-day logic
UPS Ground operates Monday through Friday, with weekend delivery available only in select metro areas or during peak season for an additional fee. When calculating transit time, UPS counts only business days—meaning a package shipped on Friday with 3-day Ground service would be due Wednesday, not Monday.
Exceptions and exclusions
UPS excludes certain scenarios from on-time calculations, including:
- Weather delays beyond carrier control
- Incorrect or incomplete addresses requiring correction
- Packages requiring adult signature when recipient unavailable
- Customs delays for international shipments
- Force majeure events (natural disasters, strikes, etc.)
These exceptions protect UPS from service guarantee claims on Express and Air services, though UPS Ground carries no guarantee regardless.
Weekend delivery nuances
While UPS Ground traditionally delivers Monday-Friday, the carrier has expanded Saturday delivery to residential addresses in many markets. However, Saturday delivery isn’t automatically included in standard Ground service—it requires specific selection and additional fees in most cases.
Latest publicly available figures (year-round & peak)
ShipMatrix’s December 2024 audit provides the most recent comprehensive carrier comparison, showing UPS Ground’s continued leadership in reliability.
Peak season snapshot (December 2024)
During the critical holiday shipping period, ground service performance ranked:
Ground Service On-Time Performance (December 2024)
Peak season performance: UPS Ground maintains industry leadership with nearly 5 percentage points higher reliability than FedEx Ground during December 2024’s critical holiday shipping period.
- UPS Ground: 96.5% on-time
- FedEx Ground: 91.8% on-time
- USPS Ground Advantage: 90.4% on-time
These figures reflect the intense operational pressure of peak season, when daily package volumes can increase 40-50% above normal levels.
Year-round average trends
While comprehensive 2024 annual data isn’t yet available, historical patterns suggest year-round performance typically runs 1-2 percentage points higher than peak season rates. This would put UPS Ground’s estimated annual average around 97-98% for 2024.
Ground vs. Air comparison
UPS Express and Air services maintain higher on-time rates (typically 98-99%) due to guaranteed service levels and priority handling. However, these services cost 2-4x more than Ground, making reliability the key differentiator for cost-conscious shippers.
How to verify your own UPS Ground OTD
Merchants shouldn’t rely solely on industry averages—tracking your specific performance reveals opportunities for improvement and helps validate carrier selection.
Pulling data from UPS Billing Center
The UPS Billing Center provides detailed shipment history including tracking numbers, ship dates, delivery dates, and service types. To extract on-time data:
- Log into your UPS Billing Center account
- Navigate to “Reporting & Search”
- Select date range and filter for Ground shipments
- Export results to CSV format
- Calculate days between ship date and delivery date
- Compare against UPS’s committed delivery date
Building a simple OTD dashboard (CSV + pivot)
Once you’ve exported UPS data, create a basic dashboard using spreadsheet pivot tables:
Key metrics to track:
- Overall on-time percentage by month
- Performance by destination zone (1-8)
- On-time rate by package weight/size
- Seasonal performance variations
- Late delivery patterns (which days/routes struggle)
Sample pivot table structure:
- Rows: Month, Destination Zone
- Columns: On-Time (Yes/No)
- Values: Count of shipments, percentage
Setting tolerance thresholds
Establish clear performance thresholds that trigger action:
- Green (95%+): Acceptable performance
- Yellow (90-94%): Monitor closely, investigate patterns
- Red (<90%): Immediate action required—consider alternative carriers or service levels
Factors that influence Ground performance
Multiple variables affect UPS Ground reliability, many outside direct carrier control.
Zone-to-zone distance
UPS divides the continental US into 8 shipping zones based on distance from origin. Longer distances (zones 6-8) typically show 1-2% lower on-time rates due to increased handling and transit time. Cross-country shipments face higher risk of weather delays and sorting facility bottlenecks.
Pickup cut-off times
Late-day pickups often miss the evening sort, effectively adding one business day to transit time. UPS Ground pickups after 5 PM typically don’t enter the network until the following business day, impacting delivery commitments.
Seasonal network adjustments
During peak season (November-January), UPS temporarily adjusts service commitments and adds Saturday delivery to manage increased volume. These adjustments help maintain on-time performance but may extend standard transit times by one day.
Labor and weather variables
Regional weather events, labor shortages, and facility capacity constraints create localized performance variations. The 2024 holiday season saw minimal weather disruption, contributing to UPS’s strong 96.5% performance.
UPS Ground vs. competing services
Understanding competitive performance helps merchants optimize their carrier mix and set customer expectations.
FedEx Ground comparison
FedEx Ground’s 91.8% December 2024 on-time rate trails UPS by nearly 5 percentage points. FedEx Ground typically costs 5-10% less than UPS Ground but offers lower reliability. For price-sensitive, non-urgent shipments, this trade-off may be acceptable.
USPS Ground Advantage comparison
USPS Ground Advantage achieved 90.4% on-time performance in December 2024, though this drops to 84.7% when excluding Parcel Select last-mile deliveries. USPS offers the lowest rates but significantly lower reliability, making it suitable only for non-time-sensitive shipments.
When multi-carrier routing wins
Smart merchants use multiple carriers strategically:
- UPS Ground: Time-sensitive shipments, premium customers
- FedEx Ground: Cost-sensitive shipments with flexible timing
- USPS Ground Advantage: Low-value items where cost trumps speed
Multi-carrier shipping software can automatically route each package to the optimal carrier based on destination, urgency, and cost parameters.
Action plan for merchants
Transform on-time delivery data into operational improvements with these concrete steps.
Establish KPIs & SLAs
Set clear performance standards:
- Minimum acceptable OTD: 95% for UPS Ground
- Review frequency: Monthly performance analysis
- Escalation triggers: Two consecutive months below 93%
- Customer communication: Proactive updates for late shipments
Merchant Performance Thresholds
Automate late-shipment alerts
Implement tracking notifications that alert your team when shipments exceed expected delivery dates. Many shipping platforms offer automated alerts when packages show “exception” status or miss delivery commitments.
Negotiate refunds/credits
While UPS Ground offers no service guarantee, high-volume shippers can often negotiate performance credits or rate adjustments based on actual delivery performance. Document your on-time data to support these discussions during contract renewals.
Continuous improvement loop
Monthly performance reviews should identify:
- Problematic shipping lanes or zones
- Seasonal performance patterns
- Opportunities to upgrade service levels for critical shipments
- Alternative carrier testing for underperforming routes
Third-party audits & methodologies
Independent auditing firms provide the most reliable on-time delivery data, as they track actual shipment performance rather than carrier-reported statistics.
ShipMatrix approach
ShipMatrix calculates on-time percentage by comparing actual delivery dates against the committed delivery window for each service level. Their methodology:
On-Time Percentage = (Total On-Time Deliveries ÷ Total Deliveries) × 100
ShipMatrix tracks millions of shipments across all major carriers, providing industry-standard benchmarks. They exclude carrier-reported exceptions in their “raw” OTP calculations but also publish adjusted figures that account for legitimate delays.
Convey by project44 approach
Project44’s Convey platform uses predictive analytics to forecast delivery dates and measure carrier performance against those predictions. Their approach factors in historical performance, current network conditions, and seasonal adjustments to provide dynamic on-time calculations.
Internal merchant data vs. public reports
Merchant-specific performance often differs from published industry averages due to factors like shipping zones, package characteristics, and pickup timing. A retailer shipping primarily within 1-2 zones may see 98%+ on-time rates, while those shipping coast-to-coast might experience lower performance.
Interpreting “high 90s” marketing language
When carriers tout “high 90s” on-time performance, the actual figures typically range from 94-98% depending on measurement methodology and time period. Peak season performance usually drops 2-4 percentage points from annual averages due to increased volume and weather challenges.
