Both of these tools do the same fundamental job. They pull data out of your marketing platforms and push it into a dashboard so you stop copying numbers into a spreadsheet every Monday.
The difference is how they count what you are buying, and it produces a much bigger gap than the headline prices suggest. Supermetrics counts data sources tightly. Power My Analytics stops counting them at the second tier.
I manage ad accounts and reporting for high-ticket stores at E-Commerce Paradise, and this comparison usually resolves in about two minutes once you list the platforms you actually need to connect. Let me show you why.
Unlimited Data Sources for Under $84
Connect every platform your store touches on one plan, with a 14-day trial that does not ask for a credit card.

Power My Analytics runs $41.63, $83.29 and $166.63 before custom pricing. Supermetrics runs $44 and $177 on annual billing before enterprise quotes.
Count Your Sources First
This is the whole decision, so do it before you read anything else. Write down the platforms you need connected.
A normal high-ticket ecommerce stack is Google Ads, Meta Ads, Shopify, Klaviyo and Google Analytics. That is five.
On Power My Analytics, five sources is exactly the Business plan at $41.63. You fit, with no headroom but no problem.
On Supermetrics, Starter covers three. Google Ads, Meta and Shopify consumes all three and you have nothing left for email or analytics, which pushes you to Growth at $177 for six sources.
So the same five-platform stack costs roughly $42 on one tool and $177 on the other. That is a four-fold difference for identical coverage, and it is not a promotional quirk, it is how the two products are structured.
Where It Flips
If you genuinely only need three sources, Supermetrics Starter at $44 is competitive and you should not pay for capability you will not use.
That is a real scenario for a store running Google Ads only, with Shopify and GA4 alongside. Three sources, no Meta, no separate email reporting. If that is you, the gap closes to almost nothing.
Where Supermetrics Earns Its Premium
I am not going to pretend the price difference means Supermetrics is bad. It is the category standard for a reason and there are situations where the premium is justified.
Connector Reliability
Supermetrics connectors break less often and recover faster when an upstream API changes. If your reporting is a billable deliverable to a client rather than an internal convenience, that reliability is part of what you are selling.
Historical Backfill Depth
When you connect a new source, how far back the tool pulls matters enormously for year-over-year comparison. Supermetrics generally handles awkward historical backfills better, which is worth confirming during your trial if seasonal comparison drives your decisions.
Transformation Capability
Once you get into genuinely complex data modelling, blending sources and reshaping fields before they hit the dashboard, the bigger platform has more room. Most stores under seven figures never reach that ceiling, but agencies do.
It Is What Agencies Already Know
If you hire a contractor to build your reporting, there is a decent chance they already work in Supermetrics. Paying more for a tool your specialist knows can be cheaper than paying them to learn a new one.
Build the Dashboard Before You Pay Anything
The free Sample Data plan gives you every connector loaded with test data and full Data Builder access, so your trial clock starts with the layout already done.
Where Power My Analytics Wins
Unlimited Sources at the Second Tier
The Grow plan removes the source count entirely at $83.29. That is half the price of Supermetrics Growth and it lifts the constraint rather than raising it to six.
For anyone running more than one store, or anyone whose stack grows over time, that structural difference compounds. You are never again choosing which platform to disconnect.
The Free Sample Data Plan
Unlimited connectors loaded with sample data, full Data Builder access, no cost. That is a genuinely smart free offer because it lets you design and test your entire dashboard layout before your trial clock starts.
Supermetrics has no equivalent, so your 14 days there covers both learning the tool and building the thing.
Ecommerce Reporting Templates
Prebuilt templates aimed at store reporting rather than generic marketing dashboards. That saves an afternoon and, more usefully, tells you which metrics somebody who has done this before thinks belong on the page.
Accounts Per Source
Grow gives seven accounts per source and Pro gives twenty. If you run several ad accounts under one platform, which is normal for anyone managing multiple stores or clients, that structure is more generous than paying per source.
Which One for Your Situation
Single Store, Full Stack
Power My Analytics Business at $41.63. Five sources covers ads, store, email and analytics, and you are paying a quarter of what the equivalent Supermetrics coverage costs.
Single Store, Google Ads Only
Either, and honestly consider neither. If Google is your only paid channel, connect it to Looker Studio natively for free and revisit when you add a second platform. I made that case in my breakdown of Power My Analytics pricing.
Multiple Stores
Power My Analytics Grow at $83.29 for unlimited sources and seven accounts per source. Supermetrics caps you at six sources for twice the money, which is the wrong direction.
Agency Billing Clients for Reporting
This is the genuine coin flip. Supermetrics if reliability is what the client is paying for and your team already knows it. Power My Analytics Pro at $166.63 if you want twenty accounts per source and unlimited admins at a lower cost than Supermetrics Growth.
Complex Data Modelling
Supermetrics, or something further up the market entirely. If you are blending and transforming heavily, the cheaper tool will eventually constrain you.
Run the Trial Properly
Both give you 14 days without a credit card, so there is no reason not to test both simultaneously on the same accounts.
Connect the same three platforms to each and compare the same week. What you are looking for is not features, it is whether the numbers agree. Small differences in how each tool handles timezones and attribution windows show up here, and it is much better to discover that during a trial than during a quarterly review.
Build one real report rather than exploring. Pick the four things you would actually check on a Monday, build exactly that in both tools, and see which one got you there faster.
Test the Refresh Behaviour
Set both tools to the same refresh schedule during the trial and check whether your store data and ad data land at the same hour. If they do not, your dashboard will show a full day of spend against a partial day of revenue.
That mismatch makes Mondays look terrible and Fridays look great for reasons that have nothing to do with your business, and it is the single most common way these dashboards mislead people who trust them.
Daily refresh overnight is right for almost every store. Hourly mostly shows you attribution being revised in real time, which is noise dressed up as immediacy.
Check Your Specific Connectors
Both cover Google Ads, Meta, Shopify and GA4 properly. The gaps appear further out, so if your stack includes something less common, verify it exists on both before you compare anything else.
WooCommerce and BigCommerce support in particular is worth testing against your actual store rather than trusting a logo on a marketing page.
What Neither One Fixes
A connector moves numbers. It does not make them correct, and a clean pipeline delivering wrong data into a beautiful chart is more dangerous than a messy spreadsheet, because the polish makes it convincing.
If your GA4 event collection is misconfigured, both tools will faithfully report the error. Fix collection before you buy visualisation.
Attribution disagreement is the other constant. Google and Meta will both claim the same conversion and no connector reconciles that for you. Google’s conversion tracking documentation explains how their side counts, and understanding that is worth more than either subscription.
And a dashboard nobody opens is worse than no dashboard. Decide what decision the report informs before you build it, or you will end up with a beautiful page that creates the feeling of being data-driven without any of the substance. Looker Studio’s documentation is worth skimming so you understand what the destination can actually do.
The Five-Year Cost Nobody Calculates
Reporting tools are among the stickiest software you will ever buy. Once your team checks the same dashboard every Monday for a year, moving becomes genuinely painful, so you are realistically making a multi-year decision here rather than a monthly one.
Run the numbers on that basis. Five sources on Power My Analytics Business is roughly $2,500 over five years. The equivalent Supermetrics coverage on Growth is roughly $10,600 over the same period.
That eight thousand dollar gap is not a rounding error on an ecommerce P&L. It is a year of a part-time VA, or a meaningful quarter of ad budget, and it buys you the same five connectors either way.
The question worth asking is what the premium actually purchases. If the answer is reliability you will genuinely notice and a specialist who already knows the tool, it can be worth it. If the answer is brand familiarity, it is not.
Watch for Tier Creep
Both vendors price so that adding one more platform can push you a whole tier. On Supermetrics, going from three sources to four moves you from $44 to $177, which is a four-fold jump for one connector.
On Power My Analytics the equivalent step is $41.63 to $83.29, and it buys you unlimited sources rather than three more. That asymmetry is the single most consequential structural difference between these two products.
So before you commit, ask what your stack looks like in eighteen months rather than today. Most stores add platforms rather than removing them.
What Migration Actually Costs
If you are already on one and considering the other, the subscription difference is not the real cost. Rebuilding dashboards and losing historical continuity is.
Neither tool exports your dashboard configuration into the other, so you rebuild by hand. Budget a day for a straightforward setup and more if your reporting is elaborate.
Historical backfill is the bigger question. Ask each vendor how far back they pull on connection before you migrate, because if the new tool only reaches six months and your business is seasonal, you have lost year-over-year comparison for a full cycle.
Write down your key benchmarks before you switch. Last quarter’s blended cost per acquisition, your typical weekly spend by channel, your best and worst months. Those survive the migration even when the underlying data does not.
And do not migrate in Q4. Moving your reporting during your busiest quarter means flying without instruments in the exact weeks the instruments matter most.
Count Your Platforms, Then Pick
Four or more sources and the cheaper tool covers you while the expensive one does not. Fourteen days free with no card to confirm it on your own accounts.
My Verdict
For the majority of store owners reading this, Power My Analytics, and it is not close. Five sources for $41.63 against three for $44 settles the entry tier, and unlimited sources for $83.29 against six for $177 settles everything above it.
Supermetrics earns its premium in agency settings where connector reliability is part of the deliverable, where your team already knows the tool, or where you are doing transformation work that a lighter product will constrain.
Count your platforms before you decide anything else. If the number is four or more, the cheaper tool covers you and the expensive one does not, which makes this a much simpler comparison than the marketing on either site suggests.
If you want the wider field rather than a head to head, I looked at six options including two with free tiers in my roundup of the best Power My Analytics alternatives.
