Is "doubling the tax" a good way to calculate tip in Manhattan?

I'm terrible at math, and would rather not whip out my cellphone to calculate a tip at a fine dining establishment.

Can someone give me guidelines of calculating an appropriate tip based on the amount of tax I see on the bill?

  1. Can't you figure 10% of the bill in your head? Then just double it?

    Simple matter of moving the decimal point and then times 2.

    1. If you round the tax up to the next dollar and then double it, you will be at about 20%, which has become pretty much customary these days, assuming the service was good.

      1. Yes, you could double the tax, which is 8.375%. But you'd be tipping a little less than the standard 20%. To tip 20% on a bill of $23.00, move the decimal point one space left and multiply by two, for a tip of $4.60. I think that's as easy (if not easier) than doubling the tax. I'm not so hot at math myself, but this, I can handle.

          duh! sorry, don't know why that didn't occur to me earlier. *blush* thank you all

        2. For the record, NYC sales tax is now 8.875%, not 8.375%. Many people, myself included, consider doubling it a perfectly reasonable if perhaps not "generous" tip.

              Yeah..I'm pretty much double tip rounded up. On occasions where the wait staff was exceptional or if we were a big group then i'm at 20%

                I agree. I don't think 20% is standard now. Only for really good service and unfortunately, that's the exception, not the rule.
