Projected Growth Investing
Use an interactive outcome projection to make a long-term financial commitment feel tangible.
In practice: Monzo
Projected growth investing makes a long-term financial commitment tangible by turning it into a simulation the user can steer: a growth chart, a deposit slider, and a likely-range band that shows outcomes without overpromising.
Future value made visible
A projection chart shows how monthly deposits could grow over time, turning an abstract decision into a concrete number the user can picture and adjust.
Guided fund choice
A fund-choice flow presents a few risk options with an expandable breakdown, so a daunting decision becomes a few completable steps.
Context without overload
Fund details show investment geography and past performance with clear context, giving the user enough to judge the choice without burying the risk.
Why it works
A multi-year projection connects today's deposit to a future balance, helping users act on long-term intentions. A likely-range band and plain disclaimer signal that projections are estimates, not promises, which makes the whole chart more credible.
How Monzo does it
Future Value Made Visible
A multi-year projection turns an abstract decision into a concrete number the user can picture.
Guided First Steps
An investing-essentials checklist breaks a daunting decision into a few completable actions.
Present-Future Link
Connecting today's deposit to a future balance helps users act on long-term intentions.
Behavioral principles
Future Self-Continuity
Making the future balance visible helps users act on behalf of their later selves.
Steerable Simulation
A slider that moves the outcome lets users learn how a small change today compounds.
Goal-Gradient Motivation
Seeing the gap between deposits and projected growth gives a reason to contribute a little more now.
Trust Through Uncertainty
A likely-range band and plain disclaimer make the projection credible rather than salesy.
Design considerations
Projections must show uncertainty and never imply guaranteed performance, and investment risk, fees, and suitability need to stay visible rather than buried under an optimistic chart.
Implementation prompt
Use the pattern above as the reference, then prototype the same behavior in your own product surface.
I want to incorporate an interactive outcome projection into my product. The goal is to make a long-term commitment tangible by turning it into a simulation the user can steer. Please suggest how to implement this in the product: • Show the projected future outcome as a concrete number the user can picture, not an abstraction • Give them a control, such as a slider, that visibly moves that outcome in real time • Show a likely range rather than a single confident line • Break the intimidating first decision into a few completable guided steps • Connect today's small contribution to the future result, so present action feels consequential For implementation, propose: • The projection model, its inputs, and the assumptions you are willing to state out loud • Screens for the projection, the controls, and the guided first-run flow • How uncertainty is drawn and described so the chart never implies a guarantee • Where risk, fees, and suitability information sits so it is not buried under an optimistic curve • What to show when the projection is unflattering, since hiding that is where trust dies.
