It's not bad - promise! Here's an example below:
Your home is valued at $150,000. Your current CITY tax portion is: $782.55. Increasing the tax rate by three pennies will change that to $827.55, or $45 more per year. Breaking that down weekly, is 0.87 cents in increase.
Of course, that example is only for a $150,00 home. You'd have to calculate for any other value.
