The total electricity cost is determined by multiplying the number of units consumed by the applicable rate per unit.<\/span><\/p>

Formula:<\/b> Total Units Used \u00d7 Rate per Unit = Total Cost<\/span><\/p>

Example:<\/span><\/i> If you consume <\/span>500 units<\/b> at a rate of <\/span>3.99 THB per unit<\/b>, your estimated cost would be <\/span>1,995 THB<\/b>.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
