Are you working for free on leap day?

By Jeff Hoyt/MoneyTips

What strange event happens every four years? No, it's not the presidential race. We are thinking more about Leap Year.

February 29 falls on a Monday this year, making it just another workday for most people. Do you get paid for that extra day? That depends on your status and the pay policies at your workplace. If you are an hourly employee on the clock, it represents an extra workday and an extra salary for that workday, so your income for the year increases by one day's pay. If you are a salaried employee, things get a bit more interesting.

Typically, salaried employees are paid on an annualized salary basis. Your pay is spread out based on the number of increments in that year. For example, if you are paid biweekly, your salary is 14/366ths of your salary in 2016 instead of 14/365ths. You can look at it as working for free that day if you want, but it is not uncommon for salaried employees to work longer hours than the forty-day workweek -- so it is really just a matter of semantics.

The uneven division of both 365 and 366 into weekly increments, however, leads to other payroll-related leaps. For example, if you are paid weekly on a Monday, you receive an extra paycheck in years with 53 Mondays instead of the usual 52.

For workers who were paid biweekly (a typical arrangement), 2015 was a "payroll leap year" since it had 27 pay periods instead of the usual 26. Whether this resulted in actual extra pay for you depended on whether your company chose to divide your salary over 26 or 27 pay periods. (From a payroll perspective, both 2015 and 2016 can be considered back-to-back leap years.)

If an extra day's worth of wages and benefits were actually passed on to all employees in America, the cost to businesses would be approximately $33.37 per hour (average employer costs for employees as of September 2015) times almost 151 million workers, or approximately $5 billion dollars. No wonder many businesses have salaried employees working for free.

Leap years have other unusual money effects. With some banks, interest calculations can include that extra day in the basis for calculations, effectively cutting your interest rate by a tiny bit. How tiny? For reference, the difference in $100,000 earning 1 percent interest for sixty days between a leap year and non-leap year is approximately 45 cents.

On the positive side, leap years mean an extra day of many services with monthly subscription rates such as Netflix or other streaming services, cable TV, insurance coverage, and even the rent on your apartment. Enjoy your free services, but be careful of those that have a monthly limit, like data plans. You probably will not receive any slack because of the extra day -- after all, it is still the shortest month of the year even with an extra day added.

As far as the presidential campaigns go, we assume it is just a coincidence that they align with leap years. Unfortunately, nowadays that just means an extra day of campaign ads.
