what are interest rates
the proportion of a loan that is charged as interest to the borrower
Why do we need to value and compare payments made at different times?
To understand the true value of money received in the future versus today, taking into account the time value of money.
Why is a £1 paid in the future less valuable than a £1 paid today?
Due to the time value of money — money today can be invested to earn interest, making future payments worth less in today’s terms.
what is present value
Present value is the value today of a payment that is promised in the future, discounted to account for the time value of money.
What concept rewards time in financial payments?
The concept of interest rewards time by adding value to payments received in the future.
why do we need present (discounted) value
- needed to compare payments made at different times.
- It helps determine the current value of a future payment, taking into account the time value of money—the idea that money today is worth more than the same amount in the future.
formula for future cash flow
𝐶𝐹 = 𝑃𝑉 (1 + 𝑖)^𝑛
- 𝑃𝑉 ≡ today’s (present) value
- 𝐶𝐹 ≡ future cash flow (payment)
- 𝑖 ≡ the interest rate
- 𝑛 ≡ the number of years to maturity
What is the formula for future cash flow (CF) given present value (PV)?
CF = PV × (1 + i)ⁿ
How do you calculate the present value (PV) of a future cash flow?
PV = CF / (1 + i)ⁿ

- simple loan
- fixed payment loan
- coupon bond
- discount bond (aka zero coupon bond)
what is a simple loan
A simple loan involves borrowing a principal amount and paying back that principal along with interest at a set time in the future (usually at maturity).
what is a fixed payment loan
A fixed payment loan requires the borrower to make equal payments (comprising both principal and interest) over a fixed period. e.g. mortgage
what is a coupon bond
A coupon bond pays the bondholder a fixed interest payment (coupon) at regular intervals (e.g., annually or semi-annually) until the bond matures, at which point the face value (principal) is repaid.
what is a discount bond
A discount bond is purchased at a price below its face value, and the full face value is repaid at maturity. There are no periodic interest payments—just a return when the bond matures.
key differences between the instruments
Simple Loans: Repay principal and interest at maturity.
Fixed Payment Loans: Repay through equal periodic payments of principal and interest.
Coupon Bonds: Receive regular interest payments until maturity, and face value is paid at the end.
Discount Bonds: Buy below face value and receive the full face value at maturity with no regular interest payments.
what is yield to maturity
YTM is the “interest rate” that equates the present value of cash flow payments from a debt instrument with its value today.
What does the Yield to Maturity (YTM) reflect in terms of investment?
YTM reflects the return an investor will earn if the debt instrument is held until maturity, based on the current market price, interest payments, and the time to maturity.
What is another name for Yield to Maturity (YTM)
Internal Rate of Return (IRR).
What factors affect the calculation of Yield to Maturity (YTM)?
The calculation of YTM depends on the structure and the timing of payments and repayments.
key features of yield to maturity (3)
Equates Present Value to Current Price
Depends on Structure & Timing of Payments
Used for Comparing Bonds
YTM for simple loans formula
one single repayment at maturity
𝑃𝑉 = 𝐶𝐹 / (1 + i)ⁿ
YTM for fixed payment loans formula
The same cash flow payment every period throughout the life of the loan.
𝐿𝑉 = 𝐹𝑃 / (1 + 𝑖) + 𝐹𝑃 / (1 + 𝑖)² + ⋯ + 𝐹𝑃 / (1 + 𝑖)ⁿ
What is the general structure of a coupon bond?
A coupon bond pays fixed interest every year until maturity, plus a specified final amount (the face value)
What is the coupon rate formula for a bond?
The coupon rate is calculated as:
Coupon rate = 𝐶 / 𝐹
