What a "Pretty Good" Healthcare Cost Estimator Can Do for You

More than 4 out of 5 times, our price estimates land within 30% of the real cost. That's accurate enough to tell you whether a $25,000 hospital quote is reasonable or outrageous. In a market where the same procedure varies by 3x to 30x, that kind of reference point can save you thousands of dollars.

This is the final post in a three-part series. Part 1 covered why healthcare prices are so hard to find. Part 2 explained how we use government data to predict cash surgery costs. This post is about putting that knowledge to work; you can see these estimates for yourself on our procedures page.

You Don't Need Perfection. You Need a Reference Point.

When you buy a used car, you check Kelley Blue Book. The estimate might be off by a few hundred dollars, but it tells you whether the dealer is in the right ballpark or trying to overcharge you.

Healthcare has never had anything like that. Until now.

Our pricing formula cuts your uncertainty by more than half. Without any reference point, the typical "error" from guessing at a surgery price is about 47%. With the formula, it drops to about 17% - meaning the estimate typically lands within a few hundred to a couple thousand dollars of the real price.

Here's how often the estimates land in range:

For the vast majority of procedures, the estimate is in the right neighbourhood - and that's all you need to make three important decisions.

Decision 1: Is This Hospital Overcharging You?

This is the single most valuable use of a price estimate. You're not trying to predict the exact bill. You're trying to figure out if a quote is fair.

Say you need knee arthroscopy. Our formula estimates it should cost around $6,200 for a cash-pay patient. You start calling around:

The surgery center's quote is close to the estimate - reasonable. The downtown hospital is charging three times the expected price. The sticker price is fiction (as we covered in Part 1, posted charges can be 2.5 to 10 times the actual cost).

Even if the formula is off by a thousand dollars, the conclusion doesn't change. Whether the real average price is $6,200 or $7,250, a quote of $18,500 is clearly an outlier. The estimate doesn't need to be perfect - it just needs to be close enough to separate fair prices from inflated ones.

Decision 2: Does Medical Tourism Actually Save Money?

Over a million Americans (opens in new tab) travel abroad for medical care each year. The savings can be dramatic, but it's a big decision - you're leaving your home country, your support network, and the legal protections you're used to. You want to know the savings are real before you commit.

Say you need a coronary bypass. That runs $70,000 to $150,000 in the US (opens in new tab) without insurance. Our formula estimates a cash price around $75,000. You start looking abroad:

Those travel costs aren't hypothetical. Round-trip flights from most US cities to Shanghai run $600 to $1,000. A decent hotel in Shanghai costs $60 to $120 a night. Two weeks of accommodation, food, and local transport comes to roughly $1,500 to $2,500. China's JCI-accredited cardiac centres (opens in new tab) quote $15,000 to $25,000 for bypass surgery, and that includes the hospital stay.

Even if the formula is underestimating and the real US price is closer to $90,000, traveling to Shanghai still saves you over $65,000. When the gap is this wide, the margin of error is a rounding error.

Where the estimate helps most is with borderline cases. If an international quote is $60,000 and the US estimate is $75,000, you'd want to be more cautious. The actual savings might be slim once you factor in follow-up care back home and the time you'll spend recovering abroad.

Decision 3: How Much Should You Budget?

If you're paying out of pocket - whether you're uninsured, on a high-deductible plan, or choosing to pay cash - you need a number to plan around.

Our research shows the formula tends to underestimate prices slightly (by about 10% on average). A practical rule of thumb: take the estimate and add 15 to 20% as your budget.

For an $8,000 estimate, that means budgeting $9,200 to $9,600. You might pay less; you might pay a bit more. But you'll be in the right range rather than blindsided by a number you never saw coming.

At the 95th percentile of errors, the estimate is off by about 40%. That's a wide margin, but vastly narrower than the 3x to 30x variation you'd face walking into a hospital with no information at all.

Where These Estimates Work Best

Not all procedures are equally predictable.

Most reliable - standardized, high-volume procedures (exactly what most people are shopping for):

• Pain management (epidural injections, nerve blocks): estimates typically within ~10%

• Gastroenterology (colonoscopies, upper endoscopies): ~13

• Orthopaedics (knee scopes, rotator cuff repair): ~17%

• Eye surgery (cataracts, laser procedures): ~18%

Less predictable:

• Complex reconstructive surgery (limb salvage, microsurgery, free tissue transfers): highly variable operative times and specialised expertise that a formula can't fully capture. For these, our team researches prices directly.

• Cosmetic procedures: pricing is driven as much by surgeon reputation and market demand as by clinical complexity.

The pattern is intuitive: the more standardized the procedure, the better the estimate. Browse by specialty to see which procedures we cover.

What a Cost Estimator Can't Do

Being honest about limitations is part of what makes estimates trustworthy.

It gives you a national average, not a local price. The formula uses national Medicare rates. A knee arthroscopy in Manhattan will cost more than one in rural Oklahoma. If you live in a high-cost area, expect real prices to run above the estimate; in a lower-cost area, they may come in below. Adding geographic adjustments is the single most promising improvement we're working toward - regional Medicare data exists to make it possible.

The benchmarks are estimates too. The prices used to validate the formula come from healthcare pricing marketplaces and hospital postings, not from actual bills. They're the best publicly available data, but not perfect. High-confidence benchmarks tracked closely with the formula; lower-confidence ones were much more scattered.

Estimates tend to run slightly low. The formula is more likely to underestimate than overestimate, which is why we suggest a 15 to 20% budget buffer.

For very complex surgery, get direct quotes. About 4% of procedures in our study had errors exceeding 50%. The largest misses were concentrated in complex reconstructive and microsurgery cases. If you're facing one of these procedures, no formula-based estimate substitutes for direct quotes from the surgical team.

Why We Built This

The data already exists. Unlike hospital transparency data, which depends on hospitals choosing to comply (and most don't (opens in new tab)), Medicare payment data is public, standardised, and updated every year. Our formula works today, whether hospitals cooperate or not.

The methodology is open. We publish every number and every test in our peer-reviewed research. Anyone - a journalist, a patient advocate, a competing researcher - can check our work. That's unusual in healthcare pricing, where most tools are black boxes.

The stakes are enormous. One economist estimated (opens in new tab) that effective price transparency could save the commercially insured population between $17.6 and $80.7 billion a year. Even a fraction of that represents millions of patients making better decisions.

A cost estimator doesn't solve healthcare pricing. It doesn't replace the need for hospitals to be transparent or for insurance to be affordable. But for a patient staring at a $25,000 surgery quote with no idea whether that's fair, a reference point that says "this procedure typically costs around $8,000" can be worth thousands of dollars.

Try It Yourself

Perfect price information would require perfect transparency, and American healthcare isn't there yet. But you don't need perfection to make a better decision. You need a reference point.

Our formula won't tell you exactly what your procedure will cost. But it will tell you whether a quote is in the right neighbourhood, and in a market where the same surgery can cost $5,000 or $50,000 depending on where you go, knowing the neighbourhood is half the battle.
