Calculation formula
- S1 – the initial amount;
- Sn – total amount at the end n-th (specified) term;
- Rn – nominal annual interest rate in the form of a coefficient (equals to the percentage rate divided by 100%);
- M – the number of selected time units per year (365 or 366 days, 12 months, 52 weeks, 4 quarters or 1 year);
- N – period in selected units (days, weeks, months, quarters or years).
The amount of accrued interest (I) equals the difference between the final and initial amounts (I = Sn – S1).
Yield in percent (D%) is calculated as follows:
