Payback Period Calculator (for single Windows PC only)

(0)
Payback Period Calculator models when an initial investment in a business will be repaid within a five-year period, if at all. Sales for each of the five years can be input, as can the initial investment, cost price, desired profit, and whether that profit will be a mark-up or a margin. The payback period is displayed as years and weeks as well as years and months. Revenue, costs, net return and outstanding repayment are calculated for each of the five years. Payback Period Calculator is fully supported by a comprehensive help file which includes an explanation of the difference between mark-up and margin when determining profit and also how to use the system to set a sale price.
