how do you calculate in your head your restaurant bill/check all the total + tip + tax?

Answer 1

I start by dividing by 10 and go from there. Since you can easily divide by 10 by moving the decimal over one place, this can be done quickly.

Nowadays, a 10% tip is not considered much. If you want a 20% tip (most fancy restaurants), you take your 10% and double it. If you want 15%, you add half of your 10%.

For example, say I have a bill of $37.88. Moving the decimal over, gives me 3.788. I often round this up to $4. So, 15% adds half of that to give me $6, and 20% gives me $8.

You probably don't want to round up to the nearest dollar. For example, the above method would give your meal of $41.04 a whopping $10 tip if you calculate for 20%. For that reason, I suggest rounding up to what you feel comfortable. So, I take my 4.104, and round up to $4.25. Thus, my 20% gives me $8.50.

Personally, I tip as I see fit based on the server's performance. I don't go off of a base 10/15/20. As a result, I often tip more than 20% for excellent service and less than 10% for poor service.

For tax, it depends on where you are. You may want to add another 10%, though I don't know if any state actually goes that high. It's a very conservative estimate.

Answer 2

A lot of bills presented at table already have tax calculated...however...ease of calculation is directly related to you tip percentage. Example: bill is 27.95...round off to 30 times 10%= $3 + 30 = $33 $30 times 20%...2 times 3 = 6 or $6 + $30 =36. Figuring non round %'s is much harder in your head...to get 15% do: $30 times 10% = 3 and add 1/2 or $1.50 +$3 = $4.50 + 30 = $34.50...jeeze that still looks complicated...ok...do what a very rich friend of mine does...he uses a calculator watch...also try punching in tip calculator on yahoo search.

Answer 3

Well, the total bill + tax is shown on your bill. So, to easily figure out the tip (15%), take the meal total (without tax) and figure out 10%, then add it to half of 10% to get the tip.

For example, if your meal total is $25.00, 10% is 2.50, half of that is 1.25, so the tip would be 2.50+1.25=3.75. This should be the only part you have to calculate in your head. If I'm trying to figure out a hard tip, I write on the back side of the receipt.

Answer 4

Take the total (including tax), slide the decimal one digit to the left, and multiply by 2. That's a 20% tip, which is what you should be leaving anyway.
Example: $35.00 bill. Move the decimal over to the left, 3.5, then multiply by 2: $7.00 tip, grand total of $42.00.

If the waiter/waitress did a great job, add a little more. If they sucked, take a little away.

Answer 5

Take the bill+tax+drinks+liquor tax as your base amount. Move the decimal one place to the left to get 10%, divide that mount by 2 to get 5%. Decide how much you want to tip. For 10%, add that to the base amount. For 15%, add the 10% and the 5% amounts to the base amount. For 20%, double the 10% amount and add that to the base amount. Rounding your chosen tip amount up or down to nearest dollar will mean you only have to add this to the dollar portion of the base amount.

Answer 6

For some reason, I find it easier to divide the amount of the check by 6. This gives an approximately 17% tip. Then I can round up or down as I wish.

Answer 7

Most places include the tax in the total. Figure out 10% by moving the decimal point over one position. Then double it. If the service was bad, round down a bit. If it was good, round up.

Answer 8

If you want a 15% tip. Figure out 10% of the total and then take half of that 10%. Or if you want a real simple rule for dinners of one or two people merele double the sales tax and that'll be the tip.

Answer 9

know you're state tax... know how much you are going to tip (15-20% for a good waiter) then calculate... you can get a good idea by rounding...

If you're state has 6% sales tax and you are going to tip 15% round to 20 %... or just find out what 1% of your bill is (which usually already has tax in it) and then multiply by the number percent you want to tip...

say y our bill is 34.56 with tax... 1% or .01 of that is .35 cents with rounding (just move the decimal to spaces to the left)... now tip 15% by multiplying .35*15... not too difficult... its $5.25

Answer 10

i usually tip 20% bc i worked in resturants so thats easy math...
take the total (before or after tip whateve you feel like) and move the decimal point over 2 and then multiply by 2.

if the bill is $20.36 i just say ok 2.00*2= $4.

another method that my friend uses, is to multiply the tax by 2. i like my way better. easy.
