Common retirement planning advice tells you to plan on replacing 70-80% of your pre-retirement income. However, this Financial Post article argues that number may be closer to 35%. Article found via k66 of Bogleheads.
Essentially, the author segregates your income to “regular” spending and temporary “investment” spending that won’t continue into retirement. Regular consumption includes food, transportation, home and car maintenance, and insurance. Temporary spending include a mortgage, child-related costs, work-related costs, and retirement savings. The idea is that in retirement your house will be paid off and your kids will be financially self-sufficient, so those “investment” expenses will go away and you’ll need less money than you may think.

Finally, some folks will need to account for new post-retirement spending that might pop up like travel and other costly recreational activities.

Ever since we started cutting back our work hours in order to share childcare duties, Mrs. MMB and I have kept a closer eye on our monthly spending patterns. One of the headaches for budgeters is dealing with large lump-sum payments like those for home/car repairs, healthcare bills (human repairs), and home/car/life insurance. Our homeowner’s insurance is due annually (we don’t use mortgage escrow anymore), life insurance is due annually, and auto insurance is due semi-annually.
