As kids start to come into the picture, your budget may feel the strain—especially if one parent stays home to care for the kids. Whether yours is a one- or two-income family, it will take careful planning to meet your long-term goals like college savings and retirement. Just remember, your top priority is to save 15% of your income for retirement, starting with your RRSP's, enough to receive the full employer’s match. Then, you can each invest up to $5,500 a year in TFSAs. With 30 or more years until retirement, folks your age have time to let compound interest work its magic on your savings. By investing just $300 a month in good, guaranteed investment funds, you could have a nest egg worth $$1,653,249.34 by the time you reach retirement age!
