If you have taken the very sensible step to start planning financially for your retirement, you will no doubt find retirement calculators to be of great benefit to you. Careful, meticulous financial planning for the years ahead could mean the difference between a very stable, happy retirement and one which brings you nothing but stress and hardship.

For those who are keen and want to prepare for their latter years, retirement calculators can be an additional help to planning your overall investment strategy. This is why retirement calculators are often considered a vital part of retirement planning.

After finding a retirement calculator which is to your liking and simple to use (there are links to some on this page), you should take your time and make use of it carefully, possibly after even consulting a financial advisor. Using these retirement calculators on their own without additional professional advice is probably not recommended unless you are very financially clued in. But once you know what you are doing, you will find them very useful indeed. Some calculators come with better help instructions than others so try a few before deciding the one you are happiest with. Note also that not all calculators have the same input requirements, so follow the instructions carefully. The following are some of the basic general pieces of information required to make your calculations - good to know to get yourself prepared:

Current Age

Current Tax Rate – Enter your current federal tax bracket

Current Savings - The total savings you have set aside for your retirement.

Annual Retirement Income – The amount you need or desire to live on once you retire (after taxes). This amount should cover all living expenses for a year and as a guide should not be less than 70 % of your current income if you want to maintain your current standard of living.

Annual Yield – It is your expected rate of return. For stocks or mutual funds, consult a prospectus.

Retirement Age –Know the official retirement age - it differs for gender and country of residence

Retirement Tax Rate – The tax bracket you expect to be in, once you retire.

If you have this information at your fingertips, before you experiment with some retirement calculators, it should prove beneficial.

One final word of caution. Remember, retirement calculators are not always perfect, just like those pressing the buttons so always check your input figures and results very carefully before putting them to further use.
