Calc tip quickly in your head

if 15% tip:

take 10% of bill
add 50% to that figure

ie:
$45 bill (b4 taxes)

10% of 45 = 4.50
50% of 4.50 = 2.25
thus 15% tip = $6.75

Mind blown
 
just use indian tip scale, its easier:

if it starts with 1, leave $1. (e.g., $10 - $19)
if it starts with 2, leave $2. (e.g., $20 - $29)
continue this pattern. $30s = $3, $40s = $4, $50s = $5.
for $60 - $100, its still $5.

I knew a girl in college who always said "tax times 3" which I thought was a stupid way of doing it, but once you mentioned percentage, she was lost. It worked for her. Also, she was a service manager at a restaurant.
 
cheap tip.

why make things that complicated when it is so much easier?

take the tax.
double the tax.
there is your tip.

that will generally work out to about 17-18% in most states.

You must have high taxes.

Only recently did we break 7% sales tax here in Ohio, which I'm a tad bit miffed about.
 
That's a good method.

I prefer the (3 * 10%) / 2 method. Take 10%, multiply by 3, divide that by 2. It doesn't have any adding which makes it a bit easier for me.

Alternatively, I just leave a 20% tip.
 
20% is my standard tip, and I adjust from there. Round to the nearest dollar, move the decimal one place left. multiply by two. I add or deduct from that depending on the service I got.

this is atot. you really think a bunch of nerds dont know basic math?

also thats a cheap tip. we are all ballers here after all.
 
Don't worry, there's an app for figuring tip out anyways. Who needs basic math?

And yes, I know of the OP's method and use it all the time.
 
I don't know why people overcomplicate tips. I just round it off so that I give them 3-5 bucks. (less or more depending what it is)

Ex: order pizza, comes up to $21.24 at the door. I can try to figure out a percentage tip on the spot while the guy is waiting for the money, or I can give him 25 bucks and say keep the change. Much simpler. Sometimes I'll throw in a toonie especially if it's a really crappy day outside.
 
daemn..talk about cheap.....
I divide everything by 2 and that's the tip!
$35.00 +tip = $52.50
$40.00 = $60.00


etc....
 
How about multiply by .2 and go up or down a little based on how good you thought the service was? Pretty much what I do, and I rarely move down. I can only think of once in the recent past, and we were on a 9 day trip eating out every day.
 
I learned to do it the 10% way. It's easy...

@Tweak155, doing it using .1 instead of .2 means you just have to move a decimal in your head, then you can multiply by 2 to get the .2
