Is this really much easier than shifting the decimal place and then adding half the number? (Rounding at the start if you want, which you probably do.)
Haha, that's what I do.
If my cost is $14.32, I know $1.43 is 10%, and half of that is about $0.71, so the tip's $2.14 (though I tip 20%, which is even easier).

To expand on this method.
Take a number like 1230 10% of that number is 123.0 (found by shifting a decimal place) half of that is 61.5 add that to 123.0 =184.5 = 15%
