Cost Slope Solution

STEP 0: Pre-Calculation Summary
Formula Used
Cost Slope = (Crash Cost-Normal Cost)/(Normal Time-Crash Time)
CS = (CC-NC)/(NT-CT)
This formula uses 5 Variables
Variables Used
Cost Slope - The Cost Slope is defined as the in­crease in the cost of the activity per unit decrease in the time.
Crash Cost - Crash Cost is the cost associated when the project is completed with the crash time of the project.
Normal Cost - Normal Cost is the cost associated when the project is completed within the normal time.
Normal Time - (Measured in Day) - Normal Time is the amount of time initially planned to complete the activity.
Crash Time - (Measured in Day) - Crash Time is the amount of time that activity will take if the additional resources are expended.
STEP 1: Convert Input(s) to Base Unit
Crash Cost: 400 --> No Conversion Required
Normal Cost: 300 --> No Conversion Required
Normal Time: 7 Day --> 7 Day No Conversion Required
Crash Time: 6 Day --> 6 Day No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
CS = (CC-NC)/(NT-CT) --> (400-300)/(7-6)
Evaluating ... ...
CS = 100
STEP 3: Convert Result to Output's Unit
100 --> No Conversion Required
FINAL ANSWER
100 <-- Cost Slope
(Calculation completed in 00.004 seconds)

5 Time Cost Relation Calculators

Crash Time given Slope
Go Crash Time = -(((Crash Cost-Normal Cost)/Cost Slope)-Normal Time)
Crash Cost given Cost Slope
Go Crash Cost = (Cost Slope*(Normal Time-Crash Time))+Normal Cost
Normal Cost given Slope
Go Normal Cost = Crash Cost-(Cost Slope*(Normal Time-Crash Time))
Normal Time given Slope
Go Normal Time = ((Crash Cost-Normal Cost)/Cost Slope)+Crash Time
Cost Slope
Go Cost Slope = (Crash Cost-Normal Cost)/(Normal Time-Crash Time)

Cost Slope Formula

Cost Slope = (Crash Cost-Normal Cost)/(Normal Time-Crash Time)
CS = (CC-NC)/(NT-CT)

What is Cost Optimization?

The Cost Optimization is a process that should be carried out throughout the construction period to ensure that the cost of the building is kept within the estimated cost limits. Cost optimization of a project involves the collecting and measuring the cost record of a project and the work progress.

How to Calculate Cost Slope?

Cost Slope calculator uses Cost Slope = (Crash Cost-Normal Cost)/(Normal Time-Crash Time) to calculate the Cost Slope, The Cost Slope formula is defined as the ratio of an increase in cost to a decrease in time. It is useful for project analysis. Cost Slope is denoted by CS symbol.

How to calculate Cost Slope using this online calculator? To use this online calculator for Cost Slope, enter Crash Cost (CC), Normal Cost (NC), Normal Time (NT) & Crash Time (CT) and hit the calculate button. Here is how the Cost Slope calculation can be explained with given input values -> 100 = (400-300)/(604800-518400).

FAQ

What is Cost Slope?
The Cost Slope formula is defined as the ratio of an increase in cost to a decrease in time. It is useful for project analysis and is represented as CS = (CC-NC)/(NT-CT) or Cost Slope = (Crash Cost-Normal Cost)/(Normal Time-Crash Time). Crash Cost is the cost associated when the project is completed with the crash time of the project, Normal Cost is the cost associated when the project is completed within the normal time, Normal Time is the amount of time initially planned to complete the activity & Crash Time is the amount of time that activity will take if the additional resources are expended.
