Common Mistakes and How to Avoid Them When Using the Loss Calculator

Calculators mostly help us with quick solutions. For calculating complex financial metrics, users must know the intricate features of a calculator. Given below are some common mistakes and solutions to tackle these mistakes.

Mistake 1

Rounding off too soon

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Rounding numbers too soon can lead to incorrect results. For example, if the loss is $15.67, don’t round it to $16 right away. Finish the calculation first.

Mistake 2

Entering the wrong number as the original or current value

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Make sure to double-check the numbers you enter for both the original and current values. If you enter the original value as ‘600’ instead of ‘700’, the result will be incorrect.

Mistake 3

Confusing net loss with gross loss

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Net loss considers all expenses, while gross loss is more straightforward. Using the wrong calculation method can give incorrect results. Understand which loss you are calculating.

Mistake 4

Relying too much on the calculator

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

The calculator provides an estimate. Real financial situations can be more complex, so the answer might be slightly different. Keep in mind that it's an approximation.

Mistake 5

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Mixing up positive and negative signs

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Always check that you’ve entered the correct positive (+) or negative (–) signs. A small mistake, like using the wrong sign for values, can completely change the result. Make sure the signs are correct before finishing your calculation. For example, if the original value is +$2900, entering -$2900 instead of +$2900 could give you an incorrect loss.

Problem 1

Help Emily find the financial loss if her stock originally valued at $900 is now valued at $750.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"
Okay, lets begin

We find the financial loss to be $150.

Explanation

To find the financial loss, we use the formula: Loss = Original Value - Current Value

 

Here, the original value is $900 and the current value is $750. Loss = $900 - $750 = $150.

Problem 2

The original value of a machine was $1200, but its current resale value is $800. What is the loss?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"
Okay, lets begin

The loss is $400.

Explanation

To find the loss, we use the formula: Loss = Original Value - Current Value Since the original value is $1200 and the current value is $800, Loss = $1200 - $800 = $400.

Problem 3

Find the loss of an investment that was initially $6000 but is now worth $5400. After finding the loss, calculate the percentage decrease.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"
Okay, lets begin

We find the loss to be $600 and the percentage decrease to be 10%.

Explanation

For finding the loss: Loss = Original Value - Current Value

 

Loss = $6000 - $5400 = $600.

 

Percentage Decrease = (Loss / Original Value) × 100%

 

Percentage Decrease = ($600 / $6000) × 100% = 10%.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"
Okay, lets begin

We find the financial loss to be $3000.

Explanation

Loss = Original Value - Current Value Loss = $15,000 - $12,000 = $3000.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"
Okay, lets begin

The loss on the antique is $300.

Explanation

Loss = Original Value - Current Value Loss = $3000 - $2700 = $300.
