The only number you actually want to know is how low you can score and still walk away with a pass. That worry is common, because \"passing\" turns out to mean different things depending on the class, the major behind it and the school you attend. This guide walks through the real thresholds and shows you how to find the exact score you need.\u003C\u002Fp>\n\u003Ch2 id=\"the-short-answer-on-what-passes-a-college-class\">The short answer on what passes a college class\u003C\u002Fh2>\n\u003Cp>At the vast majority of US colleges, the lowest grade that still passes a class is a \u003Cstrong>D\u003C\u002Fstrong>, which sits at \u003Cstrong>60 to 69 percent\u003C\u002Fstrong> on a standard scale.

Some schools push the floor slightly lower and treat a \u003Cstrong>D-minus\u003C\u002Fstrong>, worth around 0.7 grade points, as the last passing mark, so a score in the high 50s can still scrape a pass there.\u003C\u002Fp>\n\u003Cp>Other schools round the D band differently and start it at \u003Cstrong>65 percent\u003C\u002Fstrong>, which means a 60 percent would land you a failing grade instead.

Take a student sitting at 78 percent going into a final that counts for 30 percent of the course grade: the other 70 percent of the grade is already locked in at 78. That locked portion contributes 0.78 times 0.70, which equals 0.546 and works out to \u003Cstrong>54.6 percentage points\u003C\u002Fstrong> toward the final total.\u003C\u002Fp>\n\u003Cp>To land at a \u003Cstrong>60 percent\u003C\u002Fstrong> pass, the final has to supply the remaining 5.4 points out of its 30 percent weight, so you divide 0.054 by 0.30 and get 0.18. In plain terms, a score of just \u003Cstrong>18 percent\u003C\u002Fstrong> on the final drags you across the 60 percent line, which is why a solid grade going in gives you so much room.\u003C\u002Fp>\n\u003Cp>Aiming for a C instead changes the picture.

Percentage change is the umbrella term: (new - old) ÷ old × 100, with a sign that tells the story. A positive result is a percentage increase, a negative one a percentage decrease. In practice you compute the same division either way, which is why one formula covers a raise, a discount and a stock drop.

Lose 50% of 200 and you hold 100; the missing 100 now equals 100% of what you have left. The percentages refuse to cancel since each references a different starting point. The rule scales in both directions: a 20% loss needs a 25% gain and a 90% loss needs a 900% gain.

The answer sits in labor law. Under federal rules, employers may pay tipped workers a cash wage of just \u003Ca href=\"https:\u002F\u002Fwww.dol.gov\u002Fagencies\u002Fwhd\u002Fstate\u002Fminimum-wage\u002Ftipped\">2.13 dollars per hour\u003C\u002Fa>, as long as tips bring them up to the regular 7.25 dollar federal minimum. The employer claims the difference, up to 5.12 dollars per hour, as a tip credit. Seven states, among them California, Nevada, Oregon and Washington, have scrapped the credit and require the \u003Cstrong>full state minimum wage before tips\u003C\u002Fstrong>. Across much of the rest of the country, the tip makes up most of the paycheck: over a 40 hour week of the kind detailed in our guide to \u003Ca href=\"\u002Fblog\u002Fhow-to-calculate-hours-worked\">calculating hours worked\u003C\u002Fa>, the guaranteed cash wage comes to 85.20 dollars.\u003C\u002Fp>\u003Cp>Seen through that lens, a 20 percent tip at a US restaurant works like a service charge that never got printed on the menu. Skipping it over slow kitchen service punishes the wrong person: the kitchen was slow while the server refilled your water. Tip the service you received, and raise food problems with the manager instead of the tip line.\u003C\u002Fp>\u003Cdiv class=\"callout\">\u003Cp>\u003Cstrong>💡 Frozen since 1991.\u003C\u002Fstrong> The 2.13 dollar federal cash wage for tipped workers has not increased in over three decades. The Pew survey above found that \u003Cstrong>72 percent of Americans\u003C\u002Fstrong> say tipping is now expected in more places than five years ago, so the custom keeps spreading while the wage floor under it stands still.\u003C\u002Fp>\u003C\u002Fdiv>\u003Ch2 id=\"splitting-the-bill\">Splitting the bill without the spreadsheet\u003C\u002Fh2>\u003Cp>Group dinners are where good tipping intentions go to die.

In most of Western Europe, a service charge is built into the menu price or added by law, so locals round up or leave 5 to 10 percent for standout service; nobody computes 20 percent of anything. In Japan, tipping is not practiced at all and can cause real confusion, with staff chasing you down to return money you forgot. The safe rule when traveling: look up the local custom before the first meal, and when in doubt, round up modestly rather than importing US percentages.\u003C\u002Fp>\u003Ch2 id=\"faq-is-15-percent-ok\">Is 15 percent still an acceptable tip?\u003C\u002Fh2>\u003Cp>Yes, at the bottom of the acceptable range. The \u003Ca href=\"https:\u002F\u002Femilypost.com\u002Fadvice\u002Fgeneral-tipping-guide\">Emily Post Institute\u003C\u002Fa> still lists \u003Cstrong>15 to 20 percent pre-tax\u003C\u002Fstrong> as the standard for table service, and Pew found a majority of Americans say they would tip 15 percent or less. In larger cities the working baseline has moved to 18 or 20, so 15 percent for ordinary service reads as slightly cool without being rude. Reserve anything below 15 for service with a real problem, and pair it with a word to the manager so the message lands where it should.\u003C\u002Fp>\u003Ch2 id=\"faq-pre-tax-or-total\">Do you tip on the bill before or after tax?\u003C\u002Fh2>\u003Cp>Etiquette says \u003Cstrong>before tax\u003C\u002Fstrong>: the tip rewards service, and the tax is not a service. On a 100.00 bill with 8 percent tax, 20 percent pre-tax is 20.00 while 20 percent of the 108.00 total is 21.60. The difference stays small on everyday checks, which is why so many people tip on the total without thinking about it, and that habit is fine. Where it becomes worth the attention is a large group bill, where tipping on the taxed total of several hundred dollars adds real money.\u003C\u002Fp>\u003Ch2 id=\"faq-takeout\">Should you tip on takeout?\u003C\u002Fh2>\u003Cp>No tip is owed for walking in and picking up a bagged order; counter staff are paid the standard minimum wage rather than the tipped wage. A tip becomes a kind gesture rather than an obligation in two cases: a \u003Cstrong>large or complicated order\u003C\u002Fstrong> that someone had to pack carefully, and a place where the same staff cook and hand you the food. Around \u003Cstrong>10 percent\u003C\u002Fstrong> covers either case. The checkout screen suggesting 25 percent for handing you a coffee is a prompt, and you may tap No tip without guilt.\u003C\u002Fp>\u003Ch2 id=\"faq-service-charge\">Do you tip when a service charge is already on the bill?\u003C\u002Fh2>\u003Cp>No. A \u003Cstrong>service charge or automatic gratuity of 18 to 20 percent\u003C\u002Fstrong> replaces the tip, so adding a full tip on top pays twice for the same service. Read the bill line by line first; the charge usually appears for parties of six or more or at restaurants that have moved to service-included pricing. If the automatic charge covered mediocre math on your share of a big table, check it: the \u003Ca href=\"\u002Ffinance\u002Ftip-calculator\">tip calculator\u003C\u002Fa> shows in seconds what each person owes with the charge counted as the tip.\u003C\u002Fp>\u003Ch2 id=\"faq-bad-service\">What if the service was bad?\u003C\u002Fh2>\u003Cp>Tip at the low end of the range rather than zero, and separate the kitchen from the server. Cold food and a 45 minute wait for a table are kitchen and management failures; the server controls attentiveness, accuracy and refills. Given that the tipped cash wage can be \u003Cstrong>2.13 dollars an hour\u003C\u002Fstrong>, a zeroed tip lands on the one person at the table who probably did not cause the problem. For service that was rude or absent, 10 percent plus a calm word to the manager communicates more than an empty tip line, which reads as forgetfulness as often as protest.\u003C\u002Fp>",[314,246],"finance\u002Ftip-calculator","2026-07-17T11:46:49.610Z","2026-07-17T12:01:35.587Z",[318,322,326,330],{"id":319,"question":320,"answer":321},300,"How much should I tip on a 50 dollar dinner bill?","\u003Cp>At the standard 18 to 20 percent, a 50 dollar check means a tip of 9 to 10 dollars, for a total around 60.
