Contribution calculator

See how contributions change your FI date

Your monthly contributions are one of the most powerful levers in your FI plan. Yield Clarity lets you model different contribution amounts and phases to see exactly how each change affects your projected FI date and probability.

Contribution phases

Life doesn't have a single contribution amount. Yield Clarity supports multiple contribution phases so you can model your plan accurately.

Higher contributions now

Model aggressive saving during high-earning years, then reduce contributions later.

Career breaks

Add a phase with zero contributions to model a sabbatical or career change.

Stop at retirement

Contributions can stop automatically when you reach your FI target or planned retirement date.

Phase transitions

Seamless handoff between phases — no gaps, no overlaps.

Impact analysis

Scenario comparison

Compare different contribution strategies side by side.

The compound effect of contributions

An extra £500 per month may seem modest, but compounded over years with investment returns, it can shift your FI date by 20 months earlier. Yield Clarity shows both the expected-path effect (a shifted FI date) and the probabilistic effect (a higher probability of success).
