### Trigger the Cash Flow Calculation Engine
Click **"Calculate"** to execute TreasuryView's automated Cash Flow calculation.
> **What happens when you click Calculate:** TreasuryView's valuation engine performs the following in sequence:
>
> - Reads the current Nominal, rate configuration, Payment Frequency, Day Count Convention, and Amortisation Type from the deal record
> - Generates a complete period-by-period amortisation schedule from the Value Date to the Maturity Date
> - Calculates the exact interest amount for each payment period, applying the correct Day Count Fraction for broken periods, end-of-month adjustments, and public holidays
> - For floating-rate loans: applies the current market reference rate curve (e.g., EURIBOR forward curve) to project future interest payments based on market-implied rate expectations
> - Aggregates all interest and Principal Cash Flows into a consolidated timeline
> - Updates the total outstanding Nominal balance for each period based on the Amortisation Type
>
> The entire calculation executes instantly — replacing what would otherwise require a manually maintained Excel model with complex DAYS360, EDATE, and IF-formula chains.
