Lot Calculator
Separate each item's cost and calculate profit or loss from the lot
What is the Lot Calculator?
The Lot Calculator is a tool designed to help you separate the cost of each item you purchased in a lot and determine the profit or loss you have when buying that lot. You can add one unit of each item or multiple units, and additionally you can calculate shipping/tax costs separately.
✨ What it does
- Make a quick calculation to know if the lot is worth buying
- Quickly calculate real value and profit/loss of the lot
- Identify the most important items
- Visualize data in multiple charts
📊 Common use cases
- Analyze a lot before bidding at auctions
- Buy a lot with a friend and divide the real cost equitably so each person knows how much they paid for their items
- Analyze purchased items to quickly see profit and sell those you don't want
📋 Step-by-step guide
We explain exactly how the calculator works and how you should use it.
1. Enter the price you paid for the lot
- Select your currency
- You can include shipping costs here or separate them with the "include shipping/customs costs" checkbox
2. Enter the number of different items in the lot
- Most lots have duplicate items
- If there are 10 items but 6 are the same and 4 different, you should select 5 distinct items
3. Choose if you want to separate shipping/tax costs This allows you to distribute extra costs in two ways:
- Per unit: Distributes shipping/customs costs among items equally regardless of their value
- By value: Distributes shipping/tax costs proportionally to item values in the lot. If an item represents 60% of the lot's value, it will get 60% of shipping/customs costs
4. Click generate items
- A row will be generated for each item
- If you make a mistake, you can add new rows or delete them
5. Enter your lot items' data
- Select number of units (default is 1)
- Enter a name to identify the item
- Enter the item's real value
- Recommendation: Always calculate a conservative price and check sold listings on platforms like eBay to know what buyers actually pay for the items
6. Click calculate and get the results
- Overall profit/loss result for the lot
- Individual results of what each item really cost you and what percentage of the cost that item represents
Frequently Asked Questions
No, you can add as many items as you need in the lot calculator. The system is optimized to handle lots of any size.
Currently the calculator works with a single currency per calculation. You must select your currency at the beginning and all values must be in that same currency.
At the moment the calculator doesn't save calculations automatically. We recommend taking screenshots or noting down important results before closing the page.
