Common questions

Why is this only an approximation?

Duration is linear. Large yield moves need convexity as well, which this workspace also covers on a separate page.

Is this financial advice?

No. FinanceControl tools are educational. Figures are estimates, not a quote, offer, or recommendation. Confirm with the provider and a qualified professional.
