Cost is a major concern when tackling a decking project.  To help make the process of price comparison easier, here’s a handy chart listing several types of material and their associated price in lineal feet (1×6 standard profiles).  Keep in mind that prices can vary depending on supplier and region:

Keep in mind that this is only a price comparison.  In many ways, you get what you pay for when it comes to decking material.  For instance, you’ll never have to replace an Ipe deck, so that $2100 price tag is a one-time purchase, whereas you may have to replace a Pressure-Treated deck a couple times, which will boost that measly $600 to a more daunting $1800.
