The rate you see isn\u2019t always the rate you pay. <strong>CostCurve<\/strong> is an interactive graph that shows your effective electricity rate (what you&#8217;ll actually pay) at every usage level.<\/p>\n\n\n\n<h2 id=\"how-costcurve-works\" class=\"wp-block-heading\">How CostCurve Works<\/h2>\n\n\n\n<p>Over the years, our PlanScan\u2122 algorithm has calculated the true cost of thousands of Texas electricity plans. We account for usage tiers, fees, and bill credits that the advertised rate doesn&#8217;t easily reveal. CostCurve puts that same calculation into a single interactive graph. With CostCurve, simply slide along the graph to see your effective rate. The video below shows this feature in action. <\/p>\n\n\n\n<figure class=\"wp-block-video\"><video height=\"1080\" style=\"aspect-ratio: 1920 \/ 1080;\" width=\"1920\" controls src=\"https:\/\/electricityplans.com\/texas\/wp-content\/uploads\/sites\/2\/2026\/04\/Costcurve-demo.mp4\"><\/video><\/figure>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-ep-blue-light-background-color has-background\"><strong>\ud83d\udd0cPro Shopping Tip: <\/strong>Have at least one bill?
