Koyfin Alternatives in 2026

Short answer

Koyfin is the most complete Brinson attribution available outside an institutional contract, sold on advisor plans. It falls short on 8 of the capabilities scored here, starting with Decision attribution. Ranked by how many of those gaps each one closes, the strongest alternative is Pure Benchmarks, which covers 7 of the 8. Sharesight is the closer fit for investors who want accurate multi-broker performance, dividend and tax records with a benchmark attached.

People search for a Koyfin alternative for one of two reasons: the price stopped making sense, or the tool answers a different question than the one they actually have. Koyfin is the most complete Brinson attribution available outside an institutional contract, sold on advisor plans, priced at free plan, attribution from $209 per month. This page compares it against Pure Benchmarks, Sharesight, IBviz and Morningstar Investor on the capabilities that separate performance attribution tools from one another, using each vendor's own published pages rather than marketing summaries. Pure Benchmarks is our own product and is marked as such throughout, with its gaps listed in the same table as everything else.

What Koyfin does well

Separates performance against the benchmark into allocation, selection and interaction effects. Factors in every rebalance during the period, using the portfolio's weights throughout rather than only the weights at the end. Any equity ETF can be the benchmark, and it uses that ETF's historical constituents rather than only its current holdings. It is built for advisors, and individuals willing to pay an advisor price, who want allocation and selection effects done properly, and if that describes you there is no strong reason to move. Free, Plus at $39 per month and Premium at $79 per month exist, but Model Portfolios and Client Portfolios, which is where Attribution lives, start at Advisor Core at $209 per month and Advisor Pro at $299 per month.

Why people look for a Koyfin alternative

Scored against the rest of this category, Koyfin falls short on 8 capabilities: Decision attribution; Your real portfolio; Self-serve retail; Any broker; Peer baseline; Advisor review; Decision journal; Free real output. Attribution sits on the advisor tiers, so the entry price for the feature is $209 per month. Attributes to groups and holdings, not to the individual changes you chose to make. None of that makes it a weak product; it makes it a product built around a different question. The alternatives below are ranked by how many of those gaps each one closes.

How each alternative compares to Koyfin

Pure Benchmarks (Free account) closes 7 of the 8 gaps, including Decision attribution. Sharesight (Free plan up to 10 holdings, paid plans above that) closes 3 of the 8 gaps, including Your real portfolio. IBviz (Free tier, Pro at $15 per month) closes 2 of the 8 gaps, including Your real portfolio. Morningstar Investor (Subscription, free trial) closes 1 of the 8 gaps, including Self-serve retail. The table below scores all of them on the same capabilities, so the comparison reads the same way for every row.

Who should stay with Koyfin

Koyfin already covers these, and switching costs you the history you have built: Allocation vs selection. Moving makes sense only when the question you have changed. Koyfin is strongest for advisors, and individuals willing to pay an advisor price, who want allocation and selection effects done properly, and no tool on this page replaces it on that axis.

How this comparison works

Which Koyfin alternative actually closes the gap you are trying to close?

Decision journals and attribution tools are both marketed as decision tracking and they are not the same thing. A journal records your reasoning before the trade. Attribution measures the outcome afterwards. This page compares attribution tools and marks the journal capability as its own row.
The second question is who is allowed to buy it. Several of the strongest attribution engines in this category are sold to advisors or to institutions, and the attribution module specifically sits above a retail price point.
The third question is what the result is measured against. Every tool here can measure against an index. Only one measures against other real portfolios as well.
Capabilities and prices were read from each vendor's own published pages on the date shown. Vendors change both.
Pure Benchmarks is our own product. It does not produce a Brinson decomposition and it has no journal, and both gaps are marked in the table rather than described around.
FactSet, Bloomberg PORT, Confluence StatPro and Zephyr also serve this category and are institutional products sold through direct sales; they are outside the scope of a page about tools an individual can actually buy.

What each capability means

Attributes results to the individual changes you made, not only to holdings or sectors

Classic attribution answers which holding or sector drove the return. Decision attribution answers a narrower and more uncomfortable question: was the specific switch you made in March better than leaving the portfolio alone? Those are different calculations and most tools only do the first.

Produces the classic allocation, selection and interaction decomposition

The institutional standard, usually called Brinson attribution. It separates the return you earned by weighting a group differently from the benchmark from the return you earned by picking better holdings inside that group.

Runs on your own linked accounts rather than a model or a manually built portfolio

Attribution on a hypothetical portfolio is an exercise. Attribution on the account you actually own, with the trades you actually placed, is a review.

An individual can sign up and use it without an advisor licence or an institutional contract

Much of this category is sold to advisors and asset managers. If attribution sits behind an advisor tier or a sales call, it is not available to the person whose money it is.

Works across brokerages instead of being tied to one

A tool locked to a single broker can only attribute the part of your money that sits there, which for most people is not the whole picture.

Compares the outcome against other real investors, not only against an index

An index is one baseline. What comparable investors did with the same market over the same days is a second one, and it is the one that tells you whether the decision was unusual or ordinary.

Can be used to review decisions somebody else made on your behalf

If an advisor or a managed account is making the changes, attribution is the only way to see whether those changes earned their fee.

Records your reasoning before the decision, as a journal

Journalling captures intent in advance; attribution measures outcome afterwards. They are routinely confused because both are called decision tracking, and almost no tool does both well.

Free tier produces real attribution output rather than a trial countdown

Several tools here have a free plan where attribution specifically is the thing the free plan does not include.

Every tool in detail

Koyfin

The most complete Brinson attribution available outside an institutional contract, sold on advisor plans.

Best for: Advisors, and individuals willing to pay an advisor price, who want allocation and selection effects done properly.

Pricing: Free, Plus at $39 per month and Premium at $79 per month exist, but Model Portfolios and Client Portfolios, which is where Attribution lives, start at Advisor Core at $209 per month and Advisor Pro at $299 per month.

Strengths

Separates performance against the benchmark into allocation, selection and interaction effects
Factors in every rebalance during the period, using the portfolio's weights throughout rather than only the weights at the end
Any equity ETF can be the benchmark, and it uses that ETF's historical constituents rather than only its current holdings

Limitations

Attribution sits on the advisor tiers, so the entry price for the feature is $209 per month
Attributes to groups and holdings, not to the individual changes you chose to make
Custodian integration is an advisor-plan feature, so an individual is often working from a model portfolio rather than a live linked account

Pure Benchmarks

Attribution at the level of each change you made, scored against the portfolio you would still hold if you had left it alone.

Best for: Individual investors reviewing their own decisions, or an advisor's, without an advisor-tier subscription.

Pricing: A free account produces the decision report on a linked portfolio. Attribution is not held back for a paid tier.

Strengths

Freezes the portfolio as it stood immediately before each change and runs it forward alongside the real one, so every change carries its own dollar figure
Adds a second baseline beyond the index: verified connected portfolios in the same standardized risk category
Applies identically to changes an advisor or workplace plan made on your behalf
Read-only by design and unable to move money in any linked account

Limitations

Does not produce the classic Brinson allocation, selection and interaction decomposition; the unit of analysis is the decision rather than the sector weight
No decision journal. It measures what a change did, not what you expected it to do
Requires a read-only brokerage connection; there is no manual-entry-only portfolio
Does not track real estate, private holdings or self-custody crypto wallets

Sharesight

The strongest record of what happened, which is the input attribution needs, rather than attribution itself.

Best for: Investors who want accurate multi-broker performance, dividend and tax records with a benchmark attached.

Pricing: A free plan tracks up to 10 holdings with no credit card. Benchmarking is listed on the Starter plan and above.

Strengths

Separates capital gains, dividends and currency movement, which is the decomposition most retail tools skip
Benchmarks against any of more than 750,000 supported stocks, ETFs and funds
Excellent multi-broker and multi-currency record keeping

Limitations

Contribution and benchmark comparison rather than attribution to decisions
Benchmarking sits on the paid plans
No comparison against other investors

IBviz

Deep attribution visualizations at a retail price, for one broker only.

Best for: Interactive Brokers clients who want contribution and risk analytics without an advisor subscription.

Pricing: Lite is free with 80+ visualizations on a 6-month lookback. Pro is $15 per month for the full analytics and extended lookback. Corporate is $350 per month.

Strengths

Shows which assets drove returns, the FX impact on profit and loss, and risk concentration
A genuinely free tier with the full visualization set on a six-month lookback
The cheapest real attribution on this page by a wide margin

Limitations

Interactive Brokers accounts only, so anything held elsewhere is invisible to it
Attributes to assets and asset classes rather than to the decisions you made
No comparison against other investors at all

Morningstar Investor

Holdings analysis rather than attribution, and the most widely recognised name a retail investor will meet first.

Best for: Fund-heavy investors who want overlap, style and fee analysis against a chosen benchmark.

Pricing: Sold as a subscription with a free trial. No price is published on the product page, so none is stated here.

Strengths

Portfolio X-Ray breaks down allocation, sector weightings, style and fees across funds and stocks together
Benchmarks can be chosen across a range from aggressive to conservative, and indexes added for comparison
Backed by Morningstar's own fund research and ratings

Limitations

Analyzes what you hold rather than what your changes did
No decomposition of a result into the decisions that produced it
A trial rather than a free tier

Frequently asked questions

What is the best Koyfin alternative in 2026?

It depends which gap you are trying to close. On capability coverage across this comparison, Pure Benchmarks scores highest, closing 7 of the 8 gaps. Sharesight is the better pick for investors who want accurate multi-broker performance, dividend and tax records with a benchmark attached. Pure Benchmarks is our own product and is listed here with its limitations in the same table as every other tool.

Why would someone switch away from Koyfin?

Measured against the other performance attribution tools here, Koyfin falls short on Decision attribution; Your real portfolio. Attribution sits on the advisor tiers, so the entry price for the feature is $209 per month. If neither of those matters to you, staying is the cheaper decision.

Is there a free alternative to Koyfin?

Pure Benchmarks (free account with the full report). Sharesight (free up to 10 holdings). IBviz (free with a 6-month lookback). A trial is a sales window rather than a free tier, and a free plan capped at ten holdings is record keeping rather than analysis, so the table separates the two.

Which Koyfin alternative works across more than one brokerage?

Multi-custodian coverage is the weakest column in this category. Check the table before assuming a tool reads every account you hold.

How were these Koyfin alternatives compared?

Each capability was checked against the vendor's own published pages on September 17, 2026. Anything a vendor does not publish is marked as unlisted rather than estimated. Vendors change features and pricing, so the verification date is shown on the page rather than implied.
