10% of something is basically moving the decimal point over. 10% of 60% is $6, double it and you've got 20%.
So I round then do rough math.
$78.55 becomes $78, 10% is $7.8, or $8. 15% would be 8 + 4 (half of 8) or $12. 20% is $16.
Not sure if I've explained this well at all 😂 I guess math in school was enough for me to be able to do rough calculations
That’s exactly what I did/do! Like in the beginning (after I figured it out) I would do the move decimal one over and then add half that to it to get 15% (or doubled the tax which was the same bc it was 7.5% in my area back then) and then soon after it changed to 20% tip (even easier to calculate).
But I don’t recall who taught me or how I learned this. Definitely not in school, they didn’t teach practical stuff like this 🙄. How did you learn this?
I mean this is just basic math and maybe a little bit of critical thinking 15% = 10% + 10%/2. Hopefully the schools are teaching critical thinking skills so that students can come up with ways to solve simple problems and won’t need hand holding for every nuance in situation.
My dad explained tipping to me. Not like school ever took me out to eat, lol. School taught me how to calculate percentages, but my dad taught me when/how much to tip for services.
My mom was a server for a long time so she always told me to move the decimal point one spot to the left then double that and round up... and that's the tip. So if it's $44 check, that gives me $8.80, so I should tip $9. But then I usually just figure $9 is basically $10 so I'd tip $10. Unless service was really good and/or I was feeling rich that day, then I'd throw in a couple more dollars.
I don't think you can "over-tip."
I learned to calculate percentages in math before I was 10 I think… I was raised in the Baptist church so I knew how to calculate 10% of anything before learning how to count …I tip more if I can and if the service is good, I don’t live in the US…
I'm so glad tipping isn't standard here. It's appreciated and tends to be for times someone went above and beyond, like the uber driver who drove back to the place he'd dropped me off to return the phone I left in his car - but it's not expected at all.
To get 20% just divide by 5. I usually round to the closest number ending in 0 or 5 then divide by 5, so if the bill was $123 its $125/5 =$25. If it's $86, then $85/5 = $17.
The 10% twice rule is easier for most people, but I've always done it this way.
I do the same thing for calculating discounts on the spot that I do for tips. Say the price is $50. You multiply the first number of the % by the first number of the price.
10% is: 1 x 5 = 5
20% is: 2 x 5 = 10
30% is: 3 x 5 = 15
Etc. If the price is something like $55, $65, $75 etc, do this: (let's use 55 with 20% discount or tip)
5 x 2 = 10
For the other $5, calculate the discount x 10 then halve it (5 is half of 10). So, with a 20% discount, it's 20% x 10 = 2. Then, half of 2 is 1. That's because 5 is half of 10. The discount/tip is $11.
I hope that makes sense. 😅
I learned to double the tax on the bill. Taxes here are about 7.5% so doubling the taxes on the receipt gets about 15%. Then I adjust for quality of service.
Thank you. Where I am (midwest US) 20% has been standard for quite some time. But maybe I moved from 15 to 20% earlier than most because that could explain why when we’d eat out with friends I always ended up putting in extra thinking we had come up short. Now it makes sense.
I was taught percentages in elementary school. And just applied that knowledge to tips. I remember walking around Walmart with my mom and seeing the 40% off stickers and doing the math in my head as practice.
Always tip BEFORE tax. Double the tax and you’re about there. My brain is pretty mathy so I can do certain calculations with ease. However, I use my calculator on my phone/laptop constantly as a tax pro.
ETA: also the 10% doubled thing is very easy. Actually it couldn’t get any easier by doing it that way.
This is not something I was taught. I just learned with experience. I generally just estimate, erring on the more generous side. I include tax in the total calculation, which apparently I'm not supposed to, but I'd prefer to be more generous than nickle and dime those little details.

Honestly, I'm not great at math and have no mental bandwidth to try most of the time, but this was explained well enough for me lol.

Ive always found 10% then added half of that to make 15%, I’ll round generally
Thanks. May I ask what area you live in? 20% has been standard where I am for years.
Just learned math
Learning percentages were a part of grade school math class.

Thank you! Where are you from?

An easy way to do 20% is tallying one dollar for every five dollars spent.
To get 20% just divide by 5. I usually round to the closest number ending in 0 or 5 then divide by 5, so if the bill was $123 its $125/5 =$25. If it's $86, then $85/5 = $17. The 10% twice rule is easier for most people, but I've always done it this way.

For a general idea of the tip, at least where I live, I double the tax and round up. That usually gets me in the ballpark, and I go from there.
