Using an Annuity to Cover Your Essential Expenses in Retirement
One of the most practical uses of an annuity is covering the bills that arrive whether or not markets cooperate. Here is how to work out the right amount.
Key Financial Group

The short version: Work out what your essential monthly expenses are, subtract the guaranteed income you already receive, and consider covering the remaining gap with an annuity. This gives the bills a reliable source and leaves the rest of your savings free for everything else.
The idea in one paragraph
Retirement spending is not one thing. Some of it is genuinely optional and some of it arrives every month regardless of how you feel about it or what markets have done.
The essential portion is a good candidate for income you can count on. The rest can stay flexible, because if a bad year happens you can postpone a trip. You cannot postpone the property tax bill.
Matching the reliable source to the unavoidable expense is the whole idea.
Step one: find your real essential number
This takes an evening and is worth doing properly rather than estimating.
Go through twelve months of bank and card statements. Separate what you spent into two columns: what would have continued no matter what, and what you chose.
The first column usually includes housing costs including property taxes and insurance, utilities, groceries, healthcare and insurance premiums, transport, and any debt payments that are not discretionary.
Most people are surprised by the result in one direction or the other. Some find the essential number is lower than they feared. Others find that things they had filed as optional have quietly become fixed commitments.
Step two: count the guaranteed income you already have
Next, list the income that arrives regardless of markets. For most households that means Social Security, and for some it also means a pension.
Add it up on a monthly basis. Be careful to use the amount you actually receive after any deductions, not the gross figure, because the bills are paid from what lands in the account.
Step three: the gap is the number that matters
Subtract guaranteed income from essential expenses. What remains is the gap.
If guaranteed income already exceeds essentials, you may not need to do anything at all here, and that is a genuinely good position to be in. Your savings can be aimed at other jobs entirely.
If there is a gap, that figure is the natural size of the question. Not your total savings. Not a number someone else suggests. The gap.
Step four: decide how much of the gap to cover
This is a judgement rather than a formula, and a few considerations shape it.
Your other liquid savings. The more you hold in accessible accounts, the more comfortable it is to commit a portion elsewhere. If committing would leave you short of a genuine emergency reserve, the amount is too large.
Your health and family history. Guaranteed lifetime income is most valuable to people who expect a long retirement. It is a personal consideration and a legitimate one.
Your spouse. If someone depends on this income continuing after you, the payment option matters enormously. We cover that in protecting a surviving spouse financially.
Inflation. A level payment loses purchasing power over a long retirement. Covering essentials with guaranteed income while keeping other savings working is usually a better answer than trying to solve everything with one product.
Why this approach tends to work
It gives you permission to spend.
That sounds like a small thing and it is not. People who have covered their essentials with reliable income tend to be noticeably more comfortable using the rest of their savings for the things they actually retired to do. The worry that would otherwise sit under every decision has somewhere to go.
It also makes market movements far less alarming. A downturn is unpleasant. It is a different order of unpleasant when the electricity bill depends on it.
What it does not solve
It does not remove the need for liquid savings. Roof repairs and dental work do not consult your income plan first.
It does not address long term care, which is a separate and larger question worth its own conversation. We touch on it in planning for healthcare costs in retirement.
And it does not mean the rest of your money can be ignored. It means the rest of your money now has a clearer job.
Doing the arithmetic
If you want to sketch how a sum might grow before you need it, our savings growth calculator is a straightforward place to start. For the income side, the figures depend on your age and the contract, and current terms and rates are available on request.
What we would encourage is doing the first three steps yourself before speaking with anyone, including us. Walking in already knowing your essential number and your existing guaranteed income changes the conversation completely. It stops being about what someone wants to sell you and starts being about a specific gap and how best to close it.
If you would like help with that, schedule a free consultation. There is no obligation and nothing to prepare beyond what you have already worked out.
