Is medical school “worth it”? An introduction to Internal Rate of Return (“IRR”)

Finance hiring is down, law school grads are having a tough time finding real law jobs, so what is an ambitious but risk averse college student to do with his or her life these days? Okay, right now the answer is computer science. Yes seriously, do computer science. But let’s pretend it is the year 2001 and the only other option respectable option is medical school. But doesn’t med school take a lot of time (4 years school plus 3-7 years residency/fellowship) and cost a lot of money? How can we figure out if going to med school and not earning doctor money until 7 years from now is worth it financially relative to just entering the workforce and working for those 7 years?

How charitable is your favorite nonprofit?

“The more you give, the more you get, that’s being alive” – The Money Song, Avenue Q

Charitable giving serves a valuable purpose  in  our society. It allows organizations in health, education, social services and others to provide benefits to people who otherwise couldn’t afford them. It allows people who have built up wealth to give back and make a difference. The federal government even subsidizes charitable giving by allowing donations to be deducted from income reported for taxes (effectively kicking in up to 39.6% of each donation). It’s a great system that is meant to fund those people and organizations in need. At least that is how it should be. Continue reading

Build a marriage tax penalty calculator spreadsheet

Summer and Fall are generally regarded as “Wedding season,” a time when love and celebration are in the air. December, on the other hand, could be regarded as “Should we get legally married for tax reasons before the end of the year” season, a slightly less romantic affair. Continue reading

Pick up basketball: Should you shoot more 2 pointers or 3 pointers when you play winners’ take?

The NBA basketball season just started last week, and the three point shot is having its moment. Despite some high profile doubters, the Warriors are the reigning NBA champions due to very impressive three point shooting. Also, the total number of three pointers taken in the NBA has steadily risen over the past 35 years.

Is it better to take a three pointer or a two pointer? The theory behind this is pretty simple, and can be done without a spreadsheet. Because a three pointer is worth 50% more than a two pointer, if a team can hit three pointers with at least 2/3 the percentage that they hit two pointers, then they would be better off taking more three pointers.

A Simple Fantasy Football Auction Draft Spreadsheet

Last year, we demonstrated how someone can make a fantasy football draft spreadsheet to help make the best decision in each round of a traditional snake draft.  While most leagues use snake draft, eventually you might be faced with a league where someone suggests an auction draft.  They might cite something like this article to make their case.  At  first you might feel intimidated, but once you remember that every auction round is just a data driven decision, and that spreadsheets are great at solving data driven decisions, you can build something to give yourself the best chance to succeed!

Do you want the stock market to go up or down?

At first glance, it sounds like an obvious question – surely it is better when stocks go up, right? From watching the ads on CNBC, it would seem that higher stock prices directly translate into more steak dinners and golf vacations while lower stock prices mean bringing your own peanut butter sandwiches to work (jelly is for bull markets).

How to Steal Baseball Signs with Spreadsheets

Back when I was in 11th grade, I was one of the benchwarmers on the high school baseball team. Aside from needing to be ready to go in for pinch running duties, we also got assigned various tasks like statkeeper, 1st base coach, foul ball retriever and batboy (that one was the worst). Everyone left over got assigned the vague job of sign-stealing. Usually our attempts to steal signs were futile – between the wide array of touches, wipes and tugs, there was just too much going on to really keep track. But what if there were some way of using spreadsheets to enhance our sign-stealing efforts?

Use a spreadsheet to check Matthew Berry’s Top 200 Fantasy Football Rankings results from Week 1

“It’s hard to make predictions, especially about the future”  Various

Usually, improvement in prediction-making comes in two steps.  Step 1: Make a Prediction.  Step 2: Evaluate how accurate the prediction was, and learn from it.  Often times, Step 2 can get overlooked as we move on to future predictions and future weeks of fantasy football.  Spreadsheets can help us quickly evaluate how our predictions were, and quickly point out where we might have erred.
