Part 1: Introduce the RANDBETWEEN Function in Microsoft Excel
🌟 Definition: The RANDBETWEEN function in Microsoft Excel is designed to return a random integer number between two specified numbers.
🌟 Purpose: The primary purpose of the RANDBETWEEN function is to generate a random integer within a given range. This random integer is recalculated every time the worksheet undergoes a calculation.
🌟 Syntax & Arguments:
RANDBETWEEN(bottom, top)
🌟 Explain the Arguments in the function:
- Bottom: This is the smallest integer that RANDBETWEEN will return. It is a required argument.
- Top: This is the largest integer that RANDBETWEEN will return. It is also a required argument.
🌟 Return value: The function returns a random integer number between the specified bottom and top numbers.
🌟 Remarks: Every time a worksheet is recalculated, whether by entering a formula or data in a different cell or by manually recalculating (press F9), a new random number is generated for any formula that uses the RANDBETWEEN function.
Part 2: Examples of RANDBETWEEN Function in Microsoft Excel
📌 Example 1: Generating Random Sales Figures

📌 Example 3: Random Stock Quantity
Purpose: To simulate random stock quantities for products between 50 and 200.
A B (Formula) C (Result) 1 Product Stock Stock 2 Apples =RANDBETWEEN(50,200) 120 3 Bananas =RANDBETWEEN(50,200) 80 4 Cherries =RANDBETWEEN(50,200) 160 Explanation: This can help businesses understand potential stock scenarios.
📌 Example 4: Random Profit Margin
Purpose: Calculate random profit margins between 10% and 50% for products.
A B (Formula) C (Result) 1 Product Profit Margin Profit Margin 2 Shirt =RANDBETWEEN(10,50) 25% 3 Pants =RANDBETWEEN(10,50) 40% 4 Hat =RANDBETWEEN(10,50) 15% Explanation: This helps businesses in simulating different profit scenarios.
📌 Example 5: Random Delivery Days
Purpose: To simulate random delivery days between 1 and 7 for orders.
| A | B (Formula) | C (Result) | |
|---|---|---|---|
| 1 | Order | Delivery Days | Delivery Days |
| 2 | Order 1 | =RANDBETWEEN(1,7) | 3 days |
| 3 | Order 2 | =RANDBETWEEN(1,7) | 5 days |
| 4 | Order 3 | =RANDBETWEEN(1,7) | 2 days |
Explanation: This can help businesses understand potential delivery scenarios.
📌 Example 6: Conditional Bonus Allocation
Purpose: To allocate a bonus to employees based on their performance rating. If the rating is “Excellent”, a random bonus between $1000 and $2000 is given.
A B C D 1 Employee Rating Bonus Bonus Amount 2 Alice Good =IF(B2=”Excellent”, RANDBETWEEN(1000,2000), 0) $0 3 Bob Excellent =IF(B3=”Excellent”, RANDBETWEEN(1000,2000), 0) $1500 4 Charlie Average =IF(B4=”Excellent”, RANDBETWEEN(1000,2000), 0) $0 Explanation: This setup allows businesses to incentivize top-performing employees by offering them a random bonus amount when their performance is rated “Excellent”.
📌 Example 7: Sales Target Achievement
Purpose: To determine if a salesperson has achieved their random sales target.
A B C D 1 Salesperson Actual Sales Target (Random between 5000 and 10000) Achievement 2 David $6000 =RANDBETWEEN(5000,10000) =IF(B2>C2,”Yes”,”No”) 3 Eva $7500 =RANDBETWEEN(5000,10000) =IF(B3>C3,”Yes”,”No”) 4 Frank $4800 =RANDBETWEEN(5000,10000) =IF(B4>C4,”Yes”,”No”) Explanation: This method helps businesses set random sales targets for their salespeople and determine if they’ve achieved them.
📌 Example 8: Product Price with Tax
Purpose: To calculate the total price of a product after adding a random tax percentage between 5% and 10%.
A B C D 1 Product Base Price Tax % (Random between 5% and 10%) Total Price 2 Laptop $1000 =RANDBETWEEN(5,10) =B2+(B2*C2/100) 3 Phone $500 =RANDBETWEEN(5,10) =B3+(B3*C3/100) 4 Tablet $300 =RANDBETWEEN(5,10) =B4+(B4*C4/100) Explanation: This setup allows businesses to simulate the effect of different tax rates on the final price of their products.
📌 Example 9: Conditional Product Discount
Purpose: To offer a discount on a product if its stock is above a random threshold between 50 and 100.
A B C D 1 Product Stock Threshold (Random between 50 and 100) Discount 2 Jeans 80 =RANDBETWEEN(50,100) =IF(B2>C2,”10%”,”0%”) 3 Shirt 45 =RANDBETWEEN(50,100) =IF(B3>C3,”10%”,”0%”) 4 Shoes 110 =RANDBETWEEN(50,100) =IF(B4>C4,”10%”,”0%”) Explanation: This method helps businesses offer discounts on products with stock levels above a certain random threshold.
📌 Example 10: Employee Shift Allocation
Purpose: To allocate shifts to employees based on a random criterion.
A B C D 1 Employee Preference Random Number (1 or 2) Shift 2 Gina Morning =RANDBETWEEN(1,2) =VLOOKUP(C2,{{1,”Morning”},{2,”Evening”}},2,FALSE) 3 Harry Evening =RANDBETWEEN(1,2) =VLOOKUP(C3,{{1,”Morning”},{2,”Evening”}},2,FALSE) 4 Irene Morning =RANDBETWEEN(1,2) =VLOOKUP(C4,{{1,”Morning”},{2,”Evening”}},2,FALSE) Explanation: This setup allows businesses to allocate shifts to employees based on a random criterion, ensuring fairness in shift distribution.
📌 Example 11: Product Price Adjustment
Purpose: To adjust the price of a product based on a random factor.
A B C D 1 Product Base Price Adjustment Factor (Random between -5 and 5) Adjusted Price 2 Watch $200 =RANDBETWEEN(-5,5) =B2+(B2*C2/100) 3 Bag $150 =RANDBETWEEN(-5,5) =B3+(B3*C3/100) 4 Belt $50 =RANDBETWEEN(-5,5) =B4+(B4*C4/100) Explanation: This method helps businesses simulate the effect of price adjustments on their products based on random factors.
Part 3: Tips and Tricks
- Remember that the RANDBETWEEN function will recalculate every time the worksheet is recalculated. If you want to keep the generated number static, copy the cell and paste it as a value.
- Use the RANDBETWEEN function and other functions to create more complex random scenarios.
- To generate random decimal numbers, consider using the RAND function and adjusting the result to fit within your desired range.
