This means that your established handicap index can now be applied to any golf course in the world.

And in addition to the changes to the handicap index calculation, changes were also made to the course handicap calculation. These changes have now been incorporated into the Course Handicap Calculator that is included in the Learn section.

IRA Calculators Updated for SECURE Act

In case you weren't aware, once you reach a certain age you must begin making withdrawals from your Traditional IRA. These withdrawals are referred to as, Required Minimum Distributions, or RMDs. And if you fail to make an RMD you could face a possible 50% tax penalty on the shortage.

So at what age must you begin making the required minimum withdrawals? Well, up until recently, you were required to begin making RMDs once you reach age 70-1/2 (or age 71 if you turned age 70-1/2 in the last half of the year).

However, with the recent passage of the Setting Every Community Up for Retirement Enhancement (SECURE) Act, if you will reach age 70-1/2 after January 1, 2020 (born after June 30, 1949), you won't need to begin making RMDs until the year you turn age 72.

And of course, the passage of the SECURE Act also meant that I needed to update the following IRA calculators to reflect the change, which I have just completed.

Highlights and Features

Highlights and Features:

Top 10s: this tab for an introduction to this section.

Articles: this tab for links to various articles that are included on the calculator pages.

Guide: this tab for instructions on how to use this website.

Pocket Calc: this tab for a handy "pocket" calculator.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
