Account Aggregator (AA) Pricing 2026: Rate Card and Real Costs

Account Aggregator pricing has been a private matter since the network went live in 2021. Each lender and wealth platform negotiated its own terms with its AA, often through a technology service provider.

From 1 December 2026, it is a rate card. Under a circular from Sahamati, the RBI-recognised self-regulatory organisation for the AA network, data users pay a standard fee on every account they fetch. For 20 years of investment history, that comes to up to ₹96 per account, plus GST. Customers pay nothing.

The start date has moved once. Sahamati first set 1 November 2026, then pushed it to 1 December in a circular dated 26 October, citing the festive season and requests for more time. The rates are the same. Sahamati says it will share implementation and operational details in later circulars.

What changes on 1 December

• A single standard contract replaces the bilateral deals between data users, AAs and technology service providers (TSPs).
• The data user pays one bill to its AA. The AA keeps its share and passes the rest to the bank or other data provider, and to Sahamati.
• Customers cannot be charged directly for sharing their own data.
• AAs can still charge separately for value-added services such as SDKs and dashboards.

Sahamati’s circular sets the rates for the whole network, as reported by Business Standard, which reviewed it.

Maximum standard rates, before volume discounts and GST.

What 20 years of history costs on AA

Depositories and mutual fund registrars return at most two years of data per fetch, so 20 years of history takes ten fetches, each billed at the top standard rate. That is ₹96 per account, plus GST, or ₹288 for an investor with three linked accounts. It is not yet clear whether each refresh under a recurring consent is billed again.

The fee is the floor, not the total

The standard fee pays for the network: the AA, the bank and Sahamati. Everything else is billed on top. TSPs, which most institutions use to connect to AA, get no share of the fee at all.

That changes how TSPs make money. Until now, many data users paid their TSP, and the TSP paid the AA, keeping a margin on every fetch. From 1 December the fee goes to the AA under a standard contract, and that margin disappears. Business Standard reports that TSPs expect their margins to be squeezed, and one TSP founder called the model “a fundamental incentive misalignment.” TSPs will have to charge separately for integration, consent journeys and statement analysis. We expect most to raise their fees significantly.

Ten fetches, or one CAS

The two-year limit comes from Sahamati’s consent template for wealth management, CT004. The same template caps a consent at one year and allows fetched data to be kept for one month. A CAMS or KFintech CAS carries the full folio history in one document.

The costs before your first fetch

The fee only applies once you are on the network. Getting there is the larger cost.

Only entities regulated by the RBI, SEBI, IRDAI or PFRDA can become a Financial Information User (FIU), and RBI-regulated FIUs that hold financial information must also join as data providers. The FIU software, built in-house or bought from a TSP, has to be tested by a Sahamati-empanelled certifier at the certifier’s fee. Sahamati membership, which covers its dispute resolution system and API health dashboards, runs up to ₹5L a year.

The rules keep changing too. Between 31 October and 1 December 2026, FIUs have to adopt ReBIT’s client-side standards, Sahamati’s Fair Use Guidelines v2.0 and the new interoperability APIs. The new billing starts on 1 December, the last day of that window.

The customer journey has its own costs. Every AA journey means registering with an AA, logging in with two-factor authentication, matching a mobile number and PAN, linking each demat account by OTP, and approving each consent separately. Users drop off at each step, and investors without access to their Indian mobile number cannot complete it at all. We covered that case in importing an NRI portfolio without OTP.

Coverage is incomplete as well. Since March 2026, registrars no longer share demat mutual fund folios through AA, so those come from the depositories (Sahamati advisory). Bonds, debentures, EPF and PPF are still “Proposed” on Sahamati’s data types page.

The alternative: CAS, a decade older than AA

SEBI has required a Consolidated Account Statement since October 2011, and depositories have issued a combined demat and mutual fund CAS since 2015. AA went live in September 2021. CASParser converts CAS PDFs from CDSL, NSDL, CAMS and KFintech into structured JSON, with no licence or certification required.

A CDSL or NSDL CAS covers demat accounts at both depositories and eligible mutual fund folios. A CAMS or KFintech CAS covers mutual funds across fund houses, with full transaction history. See how the four formats differ.

Updates arrive without a new consent. Investors connect Gmail once with read-only access, or forward CAS emails to a dedicated import address, and each new statement is parsed on arrival. CAS Generator requests a fresh CAMS/KFintech CAS for any date range.

Plans start at ₹999 a month. A parse costs 1 credit, an inbox pull or forwarded email 0.2 credits, and failed parses are not charged.
