Small convenience purchases might seem harmless, but they do add up.

If you're like most people, you think the biggest threats to your retirement savings are major expenses like housing or medical bills. Unfortunately, everyday shopping decisions can wreak more havoc on your finances. The extra cost may be only a few dollars at a time, but over months, it can add up to a surprising amount. This is the "retirement tax": the hidden cost of paying extra for convenience today instead of saving or investing that money for the future.

Here are 11 everyday shopping habits you need to change to save money on essentials.

Pre-cut produce

Pre-cut produce saves time. Unfortunately, it's often more expensive than regular produce. While you may have mobility issues that require pre-sliced vegetables and fruit, you ultimately pay extra for the labor, packaging, and shorter shelf life of these items.

For example, a container of pre-cut pineapple may cost $4, while the whole pineapple costs $2 and yields several servings. Now think about sliced melon, diced vegetables, and chopped onions. They do add up.

If you buy pre-cut produce once or twice a week instead of using a slicer at home, you could be spending $5 to $8 more per trip.

Meal kit subscriptions

Meal kits offer convenience and less food planning, but they also cost significantly more than buying the individual ingredients at the grocery store.

A typical meal kit can cost $11 per serving, while cooking from scratch might cost only $6. If you order three meal kit dinners per week, you're looking at spending a few "from-scratch" meals' worth with nothing to show for it.

Bottled water

You may rely on bottled water because the tap water in your area isn't the best. When bought by the case, water may seem cheap, but it's actually significantly more expensive than drinking filtered water.

A case of bottled water might cost $7 and last only a few days if you use it for everything. Meanwhile, filtered water costs cents or less per glass. Switching to a reusable water bottle and a filter can cut your costs and reduce plastic waste.

Brand-name pantry staples

If you're like most shoppers, you automatically reach for familiar brand names. Store brands often contain the same ingredients at 20% to 40% less than the brand-name.

To save hundreds each year, buy generic versions of pasta, canned vegetables, flour, cereal, and baking ingredients.

Single-serve snack packs

Individually packaged snacks are great for lunches and quick bites, and you may think yourself frugal for not buying them in bulk. Still, you are paying extra for smaller portions and packaging.

Buying a large bag of nuts or crackers and portioning it yourself will save you more than buying boxes of individually wrapped snacks.

Pre-marinated or pre-seasoned meats

Stores charge extra for the preparation, marinades, and packaging of pre-seasoned meats. That's why they showcase them in eye-catching displays.

Since seasoning meat at home only requires a few pantry staples like oil, salt, herbs, and spices, you'd be remiss to spend the extra dollars for the convenience of pre-marinated chicken or pork. Besides, when you prepare the meal yourself, you know exactly what goes into it and can avoid fillers like MSG or sugar.

Bagged salad kits

We get it. Getting a bagged salad for dinner or lunch reduces prep time and gives you a much-needed break when you'd rather not be on your feet.

However, it's also more expensive than buying a head of lettuce, a cucumber, and a few toppings that can stretch over multiple meals.

Coffee shop drinks

If getting a coffee at Starbucks is your daily indulgence, you're not alone. Daily coffee shop visits are among the most common budget leaks of all demographics, not just seniors.

A specialty coffee often costs $4 to $6, while brewing coffee at home may cost as little as $0.30 per cup, depending on the brand. You don't have to eliminate this habit. Even going three days a week instead of daily can significantly reduce your yearly spending.

Grocery delivery and service fees

Grocery delivery services can save you time and are a lifesaver if you're house-bound, but they also increase your grocery bill. With their service fees, delivery fees, tips, and higher product prices, they can add $10 to $20 per order.

Using delivery occasionally might make sense, but finding a family member or a neighbor willing to help you out instead can significantly lower your food costs.

Get a protection plan on all your appliances

Did you know if your air conditioner stops working, your homeowner’s insurance won’t cover it? Same with plumbing, electrical issues, appliances, and more.

Whether or not you’re a new homeowner, a home warranty from Choice Home Warranty could pick up the slack where insurance falls short and protect you against surprise expenses. If a covered system in your home breaks, you can call their hotline 24/7 to get it repaired.

For a limited time, you can get your first month free with a Single Payment home warranty plan.

Pre-grated cheese

Shredded cheese beats buying a block and grating it yourself, especially if you have painful mobility issues. The downside is that pre-grated cheese is more expensive and contains anti-caking agents that prevent it from melting properly.

It's hard to offer alternatives that don't cost more in this department, but once again, enlisting the help of a loved one can ensure your lasagna tastes better, and you save money.

Individually bottled drinks

Much like bottled water, single bottles of iced tea, juice, or cold brew coffee often cost $3 more than a large carton or homemade version. Besides, the latter can also provide multiple servings for the same price.

Switch to larger containers or make a simple lemonade at home to reduce spending without giving up your favorite beverage.

How much this "retirement tax" could be costing you

Spending a few extra dollars on pre-cut fruit or a coffee shop drink is marketed to seniors as a small reward. Yet what's kept under wraps is the impact on your budget.

Eliminating the "retirement tax" on these categories could save you thousands each year. For example, eliminating bottled water ($200), pre-marinated meats ($150), coffee shop drinks ($1,200), and individually bottled drinks ($300) can free up $1,850 each year.

It doesn't look that minor when you look at it that way.

Bottom line

None of these purchases will single-handedly derail your retirement plans — that would be ridiculous. Still, together, they're a surprising financial mistake that can add thousands of dollars in extra spending every year.

To avoid making this mistake, try tracking convenience purchases for one month. Seeing exactly how much you spend on pre-packaged, prepared, or premium items can help you identify small changes that could save you thousands each year.
