This tool calculates the running total or cumulative sum of a series of numbers. It also computes the average of the series.
Simply enter the sequence of numbers (positive or negative) in the first row. Each number should be separate by a comma.
Example calculations
For the sequence of numbers 1, 2, 3, 4, 5 the total is 15 and the average is 15/5 = 3.
What is a Running Total?
A running total refers to the cumulative sum of a series of data values. It is a technique used to display the total accumulation of a particular variable as new data points are added. In essence, it calculates the sum of values from the beginning of a sequence up until a given point.
It is updated every time a new number is added to the sequence. Essentially the total doesn’t have to be recalculated every time a new number is added and so it’s very efficient.
For example, in an Excel spreadsheet, a running total can be computed by using a formula to continuously update the sum as new data is recorded in each row. This is particularly useful when dealing with scores or any numerical values that you want to keep track of in a progressive manner.
By using the running total technique, it becomes easier to monitor the progression and growth of a sequence of numbers over time.
Whether you need to analyze the growth of sales figures or track the scores of a sports team, a running total allows you to record and visualize the cumulative sum of your data.
The average is the running total divided by the length of the sequence.
How a Running Total Works
- Each time a new number is entered, the calculator adds that number to the previous total to get the new running total.
- It’s often used in accounting, inventory management, data analysis, and other fields where ongoing additions or changes to data need to be tracked.
Example of a Running Total
Imagine you are keeping track of daily sales:
- On day 1, you sell items worth $100. The running total is $100.
- On day 2, you sell items worth $200. The running total becomes $300 ($100 + $200).
- On day 3, you sell items worth $150. The running total is updated to $450 ($300 + $150).
Applications for a Running Total Calculator
- Financial Tracking: To calculate cumulative income or expenses over time.
- Inventory Control: Tracking stock levels as items are added or removed.
- Fitness Apps: Counting cumulative steps or calories over time.
- Data Summarization: Summing values in datasets for reports or analyses.
