Vinted Pricing Calculator

A smart calculator to help Vinted sellers optimize their pricing strategy based on storage capacity, seasonality, and market dynamics.

Features

• Dynamic Pricing Analysis: Calculates optimal price points based on probability of sale and expected value
• Seasonal Adjustments: Automatically adjusts pricing recommendations based on item type and current season
• Storage Management: Factors in your storage capacity to help balance inventory turnover
• Visual Analytics:
  • Real-time probability curves
  • Sale probability vs. expected value visualization
  • Storage pressure indicators
• Offer Evaluation: Helps decide whether to accept, counter, or hold firm on received offers

Live Demo

Usage

1. Enter your storage capacity and current inventory
2. Select the type of item you're selling (summer, winter, spring, fall, or all-season)
3. Input the listed price and days listed
4. If you receive an offer, enter it to get a recommendation
5. Use the advanced settings to fine-tune seasonal multipliers and thresholds

Advanced Settings

• Peak/Off-season multipliers: Adjust how much seasonality affects pricing
• Storage pressure thresholds: Configure when to start reducing prices due to storage constraints
• Days listed thresholds: Set the point at which items are considered slow-moving

How It Works

The calculator uses several factors to optimize pricing:

1. Base Probability Calculation: Starts with a base probability of sale that increases as price decreases, following a modified inverse relationship.

2. Time Adjustment: Items listed for longer periods receive a probability boost, reflecting the reality that some items may need price adjustments if they don't sell quickly.

3. Seasonal Multiplier: Applies a seasonal modifier based on item type and current month:

   • Peak season: Increased sale probability
   • Shoulder season: Normal probability
   • Off season: Decreased probability

4. Storage Pressure: Considers your current storage utilization:

   • High pressure: Suggests more aggressive pricing
   • Medium pressure: Balanced approach
   • Low pressure: Can be more patient for better prices

5. Expected Value: For each potential price point, calculates an expected value (price × probability) to find the optimal balance.
