One In Sixty Rule Calculator

One In Sixty Rule Calculator calculator can be used to estimate the time required to complete a task based on the time it took to complete a smaller portion of the task.

Calculation Formula

Total Task Time (T) = (Small Task Time (S) / Small Task Completion Rate (R)) / 60

Where:
T = Total Task Time (minutes)
S = Time taken to complete small task (minutes)
R = Completion rate of small task (%)

Learn how to use the One In Sixty Rule Calculator calculator and its working principles

Overview

The One In Sixty Rule is a simple estimation technique used to estimate the total time required to complete a large task based on the time it took to complete a smaller portion of the task. This rule assumes that the rate of work remains constant throughout the task.

How to Use

  1. Enter the time it took to complete a small, known portion of the task in the "Time taken to complete small task (minutes)" field.
  2. Enter the percentage completion rate of the small task in the "Completion rate of small task (%)" field.
  3. Click the "Calculate" button to compute the estimated total time required to complete the entire task.
  4. The result will be displayed in the "Total Task Time" field.

Example

If it took you 30 minutes to complete 20% of a task, the estimated total time to complete the entire task would be calculated as follows:

Total Task Time = (30 minutes / 20%) / 60 = 7.5 hours

Principle

The One In Sixty Rule is based on the assumption that the time required to complete each subsequent 1% of the task is proportional to the time taken to complete the initial small task. This makes it a quick and easy way to estimate the total time required without complex calculations.
