Answers the question: How much do I need to save to meet retirement goal? With investment schedule and charts. Supports international conventions.

Retirement Savings Calculator easily answers this question, "How much do I need to save or invest each month to reach my retirement goal?". The calculator answers the question and creates a detailed schedule with projected date based investments and charts.

Select from four predefined sizes or modify CSS file to customize size and change colors. Supports touch devices and a responsive designed website. This plugin is based on and uses the code from my Retirement Calculator.

  • First release

Can the Retirement Savings Calculator plugin be used on a commercial website?

Yes. I would be honored. Thanks.

Also, if you happen to be a financial blogger, I would encourage you to add a "Calculators" or "Tools" section to your site and include all my calculators. More content equals more opportunity. I expect to have six free plugins by early 2017.

Does your plugin have any embed advertising?

Absolutely not.

Is your plugin self contained?

Yes. 100% of the plugin is installed on your server. There are no external dependencies.

Does the plugin include any backlinks?

No, not by default. If you decide to brand the calculator with your brand and / or set the add_link option to Yes, two very discreet links are added to my site. (User will not know there are links unless their mouse passes over one.) One anchor is around the copyright in the lower left. The other around the title. Of course you are free to set the _add_link option to Yes even if you don't rebrand the calculator. :)

Is the calculator plugin responsive?

Yes. In fact, I use it on a Bootstrap responsive site.

Does the calculator support touch devices?

Yes. Users uses the calculator from all types of devices.

Do you offer other calculator plugins?

Yes. I'm offering a "Plus" version of this plugin on my website. It is free for a limited time. There will be other calculators available shortly as well.

I like your plugin and I'd like to contribute something but I notice you don't have a link for contributions, why not?

Thank you. That's very kind of you. Actually, you can contribute, and it won't cost you a cent. Please stop by my ad free website and check it out. In addition to providing some very advanced calculators, I think that I'm the only one that provides free support via a public forum. Take a look, and if you like what you see, please spread the word. That's better than any monetary compensation.

The plugin version indicates it is new. Can I trust it?

Yes. While this is a new plugin, the calculator has been used on my site for years. It has been used by literally 100,000's of users. Any issues you might encounter would most likely be around installing it on a site. Should you run into an problem, I'm happy to help resolve it.
