Supplier Quality Trend Calculator: Run Rate and Real Comparisons
Put a supplier's quality-cost trend on numbers that survive review. Enter this period, prior period and same-period-last-year costs plus periods per year; the annualized run rate and both changes come back.
What this calculator does
- Compare three actual quality-cost readings: run rate, change versus prior and versus last year.
Formula used
- Annualized run rate = cost this period × periods per year
- Change vs prior = (this period − prior) ÷ prior × 100
- Change vs last year = (this period − last year) ÷ last year × 100
- Dollar change vs prior = this period − prior
Inputs explained
- Quality Failure Cost This Period: This period's measured failure cost on one definition.
- Quality Failure Cost Prior Period: The immediately preceding period's cost, same definition.
- Cost in the Same Period Last Year: The same calendar period one year ago.
- Periods per Year: Periods per year: 12 monthly, 4 quarterly.
How to use the result
- Best suited to ranking suppliers by annualized failure cost, testing a worsening month against seasonality, verifying a corrective action against both baselines.
- Three readings distinguish better or worse; a fitted slope needs the full series. The run rate extrapolates one period, so a spike month annualizes into an alarming number.
Current U.S. benchmarks
- U.S. manufacturing runs at 75.7% of capacity (Federal Reserve, Aug 2026). New factory orders are up 8.5% year over year (Census).
Common questions
- How is the supplier quality trend computed here? From three actual readings. The run rate multiplies this period's cost by periods per year: $3,400 a month runs at $40,800 a year. The two change rows compare this period against the prior period and the same period last year.
- Why compare against the same period last year? Because seasonality is the standard false trend. Volume cycles, shutdowns and seasonal mix move quality cost with them, so a rise against the same period last year is about the supplier.
- Is the annualized run rate a forecast? No: it is this period's reading multiplied by the periods in a year, the current bleed in annual terms. It prices the do-nothing option and says nothing about direction, which the two change rows carry.
- When do these numbers justify escalation? When both comparisons are up and stay up across successive periods. One lumpy month argues for a look at the lots behind it; worse than both baselines, repeated, is deterioration no seasonal story covers.
