The computation is using the function ErlangCsrv which takes 4 arguments: first m the number of agents, second u the traffic intensity, third t the average call duration and fourth tt the target time. Practical staffing with Excel In the previous sections, we have seen how to compute useful...
There is no federal law that tells states the rate to charge. Each state and local government can set the rate at a percentage within their state guidelines. For example, the rate on a sale in Massachusetts is 6.25% across the state, but if you shop in Texas, the rate can range from...
But while calculating duration, only a change in the last factor that is the increase or decrease in benchmark rate is considered. All other factors are assumed to be constant for the sake of calculation. Further, the increase or decrease in rate is assumed to be constant in both the direc...
The function f(x)=e^-x can be used to generate the following table of unequally spaced data: Evaluate the integral from a=0 to b=0.6 using: (a) analytical means, (b) the trapezoidal rule, (c) a com Plot the forward rate coefficient k(T) for the...
Inflation Premium = (Expected Rate of Return + Inflation Rate) – Risk-Free Rate By following these steps and using the appropriate formula, investors can determine the inflation premium for their investments. This information allows them to make more informed decisions and accurately account for inf...
Using Microsoft Excel, I created a calculator to calculate local gravity using the equation above including theestimate of uncertaintyassociated with the value of gravity. If you want a copy of this calculator, click the link below and enter your email address to download it. ...
r = rate of return IRR of $200,000 investment = $20,000 *[(1-(1+r)^-30)/r] In this case, the IRR is 9.31. Excel has an IRR functionthat can be used to calculate the IRR quickly, and some calculators have this function too. ...
pandemic, the 10-year bond yield has declined to under 1%. Therefore, the value of your pension has gone way up. You want to hold onto your cash cows for as long as possible. Your reasonable return of return divisor should be lowered to 1% – 2% in this low interest rate environment....
This is the simplest formula to assign a monetary value to conversions: Event Monetary Value = Customer Lifetime Value x Lead Conversion Rate We've already covered customer LTV; lead conversion rate is the percentage of leads that convert into paying customers. Let's say you have a customer ...
calls. If there are fewer agents than the traffic intensity, then mechanically, calls will be dropped. The traffic intensity is nameduand be computed as the product of the call arrival rate λ multiplied by the average call durationt. In the spreadsheet, the traffic intensity is computed inB...
