The Problem

The tools advisers rely on today were not designed for retirement income decision making

Advisers typically operate across multiple systems — cashflow tools for long-term planning, risk tools for suitability, and platforms for execution. However, when it comes to the real retirement decisions, a clear gap remains.

  • Cashflow tools support high-level, long-term planning — but rarely optimised for the practical mechanics of drawdown

  • Risk tools assess suitability and volatility but are disconnected from ongoing withdrawal sustainability

  • Platforms enable execution — but lack a dedicated retirement-income analysis layer in between planning and implementation

  • Spreadsheets are used to bridge the gap but are inefficient, hard to audit, and difficult to scale

Can your current retirement income process consistently and accurately answer the following?

1.

How much can a client safely withdraw without running out of money?

2.

Which model portfolio performs best in retirement conditions in terms of longevity and sustainability?

3.

When should annuities be introduced, and at what allocation?

4.

How do multiple income streams — pension, state pension, rental income to deliver a reliable income?

The Solution

The AB Income Architect tool fills the critical gap between planning and implementation

The ABP Income Architect is unique in the market at the point of issue. It has been developed in collaboration with two leading professors and academics.

The methodology is grounded in peer-reviewed research on retirement income sustainability and sequence-of-returns risk.

The Methodology

Built on academic rigour, stress-tested against history

Unlike tools that rely on simple Monte Carlo simulations, AB Income Architect uses a rolling historical simulation engine — stress-testing every plan against every market sequence that has occurred. The result is defensible, evidence-based, and auditable.

Portfolio Construction

Weighted Portfolio & Fee Adjustment

A weighted portfolio is built from asset classes, each with a time series of historical returns. Client fees are deducted at the asset level — not as a post-hoc reduction — keeping everything on a consistent net basis. The geometric mean return and volatility are derived from this fee-adjusted series.
