The Family Life Office of the Diocese of Charleston, South Carolina has a Facebook page which provides a nice overview of the benefits of Natural Family Planning:
Fertility Appreciation: empowers couples to see their fertility as a gift and not as a disease to be treated.
NFP accurately identify their days of fertility and infertility either to achieve or to avoid pregnancy.
NFP affirms the dignity of the human person within the context of marriage and family life, enables and encourages responsible parenthood, promotes openness to life, and celebrates the gift of children. By respecting the love-giving and life-giving nature of marriage, NFP enriches the bond between husband and wife.
NFP is natural based upon the couple's own knowledge of their naturally occurring cyclic phases of fertility and infertility. No drugs, devices, or surgical procedures are used to avoid pregnancy. Natural Family Planning is not contraception; it is true family planning.
NFP promotes shared responsibility and loving cooperation between husband and wife.
NFP is a holistic approach to planning a family NOT a contraceptive
NFP enhances one’s expression of love within the marital vocation developing a balance of the spiritual, physical, intellectual, creative/communicative and emotional dimensions of the couple’s sexual life together.
NFP is proven effective- The effectiveness of NFP is over 99% in avoiding pregnancy when the instructions are properly taught by a qualified teacher and then correctly applied. The method is also highly effective to achieve pregnancy when couples identify and use the days of fertility. In addition, it is an essential aid in the evaluation and treatment of those couples who are experiencing infertility.
Advantages of NFP:
• medically safe
• highly reliable
• morally acceptable
• easy to learn
• fairly inexpensive
• highly versatile
• used at any stage of a woman's reproductive life
• precisely identifies days of fertility and infertility
• aid for couples who are having difficulty in achieving pregnancy

Note: Contraception, Why Not by Dr. Janet Smith is the most persuasive presentation of the Church's teaching on artificial contraception I have come across. Contraception, Why Not? is available here in CD format. I highly recommend it.
