In the US, a “salary” is something paid less frequently and is higher. A “wage” would be used for less skilled and lower paid workers, typically expressed per hour. “Wage” is also the termed used in business and economics. A “paycheck” was the physical check that businesses gave to their employees to pay them. Now payment is often done electronically, in which case the employees receive a “paystub”, by paper or email. She’ll have a salary of $1500 per week. (Typically wouldn’t track the hours worked) The minimum wage in Seattle is $15 per hour. Wages fluctuate less quickly than prices. Here’s your paycheck for last week. Colloquially people would be more likely to talk about “getting paid” than use these words. I get paid every Tuesday. We pay her $23.50 per hour with medical, vacation and retirement.

It is the same scenario and usage in the UK as per the other two answers. we use pay slip and recently pay chit has come into use or possibly been reinvented from the past, which happens to words.

Same scenario in the US as in New Zealand. A salary is paid for the job, regardless of the hours worked, and would be quoted per year. It is generally for higher level positions such as management. A wage is paid to those who earn per hour worked. A paycheck is the income you receive per pay period, for example, you are paid fortnightly on a Wednesday the payment would be the paycheck. In New Zealand we don't really use this word. You may also know of 'pay slip' which these days usually comes by email and details the pay period, hours worked, amount per hour, gross total, taxes deducted, net total, holidays owing, sick leave owing, etc. I can't tell you what's on a salary payslip though as I've never had one of those hehehe!
