How does this model work?

The monthly rate is calculated as (1 + annual rate)^(1/12) − 1. Each month, existing capital earns interest before the contribution is added. This models month-end contributions. At 0%, the final amount equals the initial capital plus all contributions.

Fluctuating actual returns lead to different outcomes. Negative assumed rates are also supported; the calculator then displays a modelled loss. The annual table makes the calculation transparent.
