HAD2KNOW FEATURED ARTICLES:


MARGINAL COST CALCULATOR

You can use this useful marginal cost calculator to compute the cost incurred
when producing additional units of a given product. Marginal cost is the
additional cost of producing further units of a product or service. You can
compute marginal cost by dividing the total expenses incurred when producing
additional units by the variation in the number of products manufactured.



INCOME ELASTICITY OF DEMAND CALCULATOR

Income elasticity of demand measures the extent to which a given good or service
is sensitive to a change in income if all other factors remain constant. Income
elasticity of demand can be computed by dividing percentage change in quantity
by the percentage change in income. It represents a useful measure because it
provides an insight into whether a given good or service is a luxury or a
necessity.



TRUE SHOOTING PERCENTAGE (TS%) CALCULATOR

The true shooting percentage statistic was first introduced by the Association
for Professional Basketball Research Metrics (APBRmetrics), and it is now very
commonly used in basketball leagues because it provides a very good indication
of a basketball player's skill. This True Shooting Percentage calculator can
help you quickly and easily compute the TS% of a given player.
