How It Works
The calculator uses your store's actual data to model three threshold strategies:
Conservative (15% above AOV)
Lower risk, lower reward. Customers reach the threshold more easily, which means:
- Higher redemption rate
- Smaller increase in average order value
- Best for stores with tight margins or high shipping costs
Moderate (25% above AOV)
The balanced approach. This is the recommended starting point for most stores:
- Good balance of reach and lift
- Meaningful AOV increase without feeling unattainable
- Works well across most product categories
Aggressive (35% above AOV)
Higher risk, higher reward. Fewer customers reach it, but those who do spend significantly more:
- Lower redemption rate
- Larger AOV increase per qualifying order
- Best for stores with healthy margins and lower shipping costs
Best Practices
Start with the data
Before setting your threshold, know your numbers:
- Average Order Value — Your baseline for comparison
- Shipping costs — What you actually pay per order
- Profit margins — Can you afford to absorb shipping?
Test and iterate
Start with the moderate threshold and measure results over 2-4 weeks:
- Track changes in AOV
- Monitor free shipping redemption rate
- Calculate actual profit impact
Communicate clearly
A free shipping threshold only works if customers know about it:
- Display progress toward free shipping prominently
- Show the threshold on product pages, cart, and checkout
- Use urgency messaging when customers are close
Consider alternatives
Free shipping isn't your only option:
- Tiered discounts (spend more, save more)
- Free gift with purchase above threshold
- Loyalty program with free shipping perk
