Industry benchmark inventory turnover rates: small (1-10 units), mid-size (11-50), large (50+) dealerships. Calculate your ideal turnover ratio.
Inventory turnover measures how many times per year you sell and replace your entire inventory. High turnover (12+ times/year = 30-day average time to sale) means fast-moving inventory, lower carrying costs, and higher cash flow. Low turnover (6 times/year = 60-day average) means slow sales, high floor plan interest, and capital tied up in aging vehicles.
This guide provides turnover ratio benchmarks by dealership size, explains how to calculate your current turnover, identifies optimal targets based on business model (volume vs margin), and offers actionable strategies to improve turnover speed without sacrificing profitability.
Method 1 - Annual Units Sold:
Turnover Ratio = Annual Unit Sales ÷ Average Inventory Count
Example: You sell 300 vehicles per year with an average inventory of 25 vehicles.
300 ÷ 25 = 12 turns per year
Method 2 - Days in Stock:
Turnover Ratio = 365 days ÷ Average Days in Stock
Example: Your average vehicle sells in 32 days.
365 ÷ 32 = 11.4 turns per year
Both methods should produce similar results. Use Method 1 for annual planning, Method 2 for real-time monitoring.
| Average Days in Stock | Turnover Ratio (per year) | Performance Level |
|---|---|---|
| 15 days | 24 turns | Exceptional (high-volume, low-margin) |
| 24 days | 15 turns | Excellent (fast turnover) |
| 30 days | 12 turns | Very Good (target for most dealers) |
| 45 days | 8 turns | Good (balanced approach) |
| 60 days | 6 turns | Acceptable (specialty/higher margin) |
| 90 days | 4 turns | Poor (carrying costs eating profit) |
| 120+ days | 3 or fewer turns | Critical (immediate intervention needed) |
| Metric | Target Range | Notes |
|---|---|---|
| Turnover Ratio | 8-12 turns/year | 30-45 days average time to sale |
| Annual Sales | 80-180 units/year | 7-15 units/month |
| Gross per Unit | $2,500-$3,500 | Higher margin compensates for lower volume |
| Inventory Investment | $100,000-$400,000 | $10,000-$20,000 average per vehicle |
Strategy: Focus on high-demand vehicles (Honda, Toyota, Ford) with proven local demand. Avoid specialty vehicles requiring 60+ days to sell. Price competitively for 30-day turnover rather than holding for maximum gross.
| Metric | Target Range | Notes |
|---|---|---|
| Turnover Ratio | 10-15 turns/year | 24-36 days average time to sale |
| Annual Sales | 300-600 units/year | 25-50 units/month |
| Gross per Unit | $2,000-$3,000 | Volume + margin balance |
| Inventory Investment | $400,000-$1,000,000 | $15,000-$25,000 average per vehicle |
Strategy: Mix 70% high-turnover vehicles (30-day target) with 30% higher-margin specialty vehicles (45-60 day target). Use aged inventory reports to identify slow movers and reprice aggressively at 45-day mark.
| Metric | Target Range | Notes |
|---|---|---|
| Turnover Ratio | 12-18 turns/year | 20-30 days average time to sale |
| Annual Sales | 900-2,000 units/year | 75-165 units/month |
| Gross per Unit | $1,800-$2,500 | Volume-focused, thinner margins |
| Inventory Investment | $1,500,000-$4,000,000 | $18,000-$30,000 average per vehicle |
Strategy: High-volume, fast-turn model with aggressive pricing. Use data analytics to identify top 20 fastest-selling models in your market and stock heavily. Reprice at 21-day mark if no leads. Wholesale or auction vehicles at 60 days to free capital for fresh inventory.
| Metric | Target Range | Notes |
|---|---|---|
| Turnover Ratio | 4-8 turns/year | 45-90 days average time to sale |
| Annual Sales | 40-120 units/year | 3-10 units/month |
| Gross per Unit | $5,000-$15,000+ | High margin compensates for slow turnover |
| Inventory Investment | $500,000-$3,000,000 | $40,000-$150,000+ average per vehicle |
Strategy: Slower turnover acceptable due to higher margins and limited buyer pool. Focus on vehicle condition, provenance, and unique features rather than price competitiveness. Use national marketing (Bring a Trailer, Cars & Bids, Hemmings) to expand buyer reach.
Every dealer must balance turnover speed against gross profit per unit. Faster turnover requires competitive pricing (lower margins), while higher margins require longer time to sale (slower turnover).
Scenario: 20-vehicle inventory capacity. Which strategy generates more annual profit?
| Strategy | Avg Days to Sale | Turnover Ratio | Gross per Unit | Annual Profit per Slot |
|---|---|---|---|---|
| High Volume | 24 days | 15 turns/year | $1,800 | $27,000 |
| Balanced | 36 days | 10 turns/year | $2,500 | $25,000 |
| High Margin | 60 days | 6 turns/year | $3,500 | $21,000 |
| Slow Turn | 90 days | 4 turns/year | $4,000 | $16,000 |
Winner: High volume strategy ($27,000 per inventory slot) beats high margin strategy ($21,000) by 29% due to faster capital recycling.
Floor plan financing (typical 5-8% APR) heavily penalizes slow turnover. Interest expense reduces effective gross profit.
| Vehicle Cost | Days in Stock | Interest Rate | Interest Expense | % of $2,500 Gross |
|---|---|---|---|---|
| $18,000 | 30 days | 6% APR | $89 | 3.6% |
| $18,000 | 60 days | 6% APR | $178 | 7.1% |
| $18,000 | 90 days | 6% APR | $267 | 10.7% |
| $18,000 | 120 days | 6% APR | $356 | 14.2% |
Lesson: Every extra 30 days in stock costs ~$89 in floor plan interest. A vehicle sitting 120 days eats 14% of your gross profit before any other expenses.
| Aging Milestone | Action | Price Adjustment |
|---|---|---|
| 0-21 days | Monitor impressions and leads | No change (test market response) |
| 21-30 days | If no leads, review price vs competition | Reduce 3-5% if priced above market median |
| 30-45 days | Reprice to market median or below | Reduce 5-8% to stimulate activity |
| 45-60 days | Aggressive reduction to move quickly | Reduce 8-12% (accept lower gross to free capital) |
| 60-90 days | Wholesale or auction consideration | Price to sell this week or send to auction |
| 90+ days | Immediate liquidation required | Wholesale, auction, or at-cost sale to recover investment |
Target 8-12 turns per year (30-45 days average time to sale) for independent used car dealers. High-volume dealers (50+ sales/month) target 12-15 turns (24-30 days). Low-volume specialty dealers (10-20 sales/month) may operate at 6-8 turns (45-60 days) with higher margins per unit.
Formula: (Annual Unit Sales ÷ Average Inventory) = Turnover Ratio. Example: 240 vehicles sold annually ÷ 20 average inventory = 12 turns/year. Alternative: 365 days ÷ Average Days in Stock = Turnover Ratio. Example: 365 ÷ 30 average days in stock = 12.2 turns/year. Both methods should produce similar results.
Common causes: (1) Overpricing (vehicles sit due to uncompetitive pricing), (2) Poor merchandising (bad photos, incomplete descriptions reduce clicks), (3) Wrong vehicle mix (buying vehicles with limited demand), (4) Slow reconditioning (vehicles stuck in prep for weeks), (5) Inadequate marketing (no one sees your listings). Fix by auditing aged inventory (60+ days) and identifying patterns.
Balance both based on cash position and floor plan costs. High turnover (low days in stock) = lower per-unit gross but higher annual profit due to volume. Example: $2,000 gross × 12 turns = $24,000/year per slot. Slow turnover (high days in stock) = higher per-unit gross but fewer annual transactions. Example: $3,500 gross × 6 turns = $21,000/year per slot. High turnover usually wins due to carrying cost savings.
Floor plan interest (typically 5-8% APR) penalizes slow turnover heavily. Example: $20,000 vehicle at 6% APR costs $100/month in interest. At 90 days in stock = $300 interest expense (15% of a $2,000 gross profit). Target faster turnover (30-45 days) to minimize interest costs. Some dealers use floor plan free days (30-90 days interest-free) strategically for aged inventory.
