What is the difference between discrete and continuous compounding?
Discretely compounded interest is calculated and added to the principal at specific intervals (e.g., annually, monthly, or weekly). Continuous compounding uses a natural log-based formula to calculate and add back accrued interest at the smallest possible intervals.
Is compounding continuously or annually better?
Over 10 years, the compounded interest will give a return of: whereas the continuously compounded interest will make: Continuous compounding always generates more interest than discrete compounding.
How will you use simple and compound interest in real life situations?
Simple interest is more advantageous for borrowers than compound interest, as it keeps overall interest payments lower. Car loans, amortized monthly, and retailer installment loans, also calculated monthly, are examples of simple interest; as the loan balance dips with each monthly payment, so does the interest.

Is Libor continuous compounding?
In your notes, you say that LIBOR is quoted on an actual/360 basis. But when using the LIBOR rate as a proxy for the spot rate it is continuously compounding.
What is SOFR compounding?
SOFR compounded in arrears is calculated by compounding interest over the current interest period. [19] Therefore, it is not known in advance of the payment date. SOFR compounded in advance is calculated by compounding interest over a previous set amount of days (i.e. tenors of 30, 90 or 180 days).
What is the difference between term SOFR and compounded SOFR?
Simple average SOFR is calculated in arrears meaning it reflects the Overnight SOFR resets during the actual accrual period. Compounded SOFR is generally reset in advance meaning that it’s actually derived from the Overnight SOFR resets from the previous period.
How often is LIBOR compounded?
These indexes publish cumulative compounded SONIA and cumulative compounded SOFR respectively on a daily basis. They are compatible with a calculation method that uses an observation shift. They do not work well with the use of a zero rate floor.
What is the difference between LIBOR and SOFR?
