Sometimes you don't have the money you want to help out your favorite charity. Your budget may be a little tight or maybe you've already spent your allotment for donations. There are still many ways you can help a charity without spending a cent.

The obvious is to donate your time. Most organizations need help and you probably have a skill that they need. For instance, if you are an accountant, you could manage the books. Or if you are an electrician, you could offer free service.

You can do a little extra in your online world. Place the website of your favorite charity or cause in the signature of your e-mail, especially if there’s a special event. Use your social media networks to spread the word about your cause. Some websites pay charities when you click on a button and view advertisements. In addition, GoodSearch pays nonprofits every time you conduct an internet search.

Use credit cards that have special programs that contribute proceeds to your charity of choice; and do business with companies that give back a percentage of sales to organizations you support. Or do some business of your own by having a garage sale or set up an eBay store. They have a system called Giving Works that allows you to donate the money and receive a tax deduction.

Try advertising your charity in subtle ways. Wear a t-shirt that showcases the organization when you go out or place a bumper sticker on your car.

There are many ways to give back to your favorite charity without spending cash, so get creative. And if all else fails, call the organization for more ideas.
