When repaying a loan and you get extra money, what are your two options?
Reduce the duration and maintain the initial installment
Reduce the installment and maintain the duration
Partial amortization means …
repaying part of a loan in a lump sum
Number of pending payments means
duration of loan
The excel formula to calculate the number of payments is
nper
The excel formula to calculate the rate is

In a loan contract, a borrower initially receives __________ from a lender, and is obligated to repay ___________ + ____________________.
initially an amount of money (called principal)
an equal amount of money to the lender at a later time (amortization of the loan), plus an additional sum of money, which is the interest of the loan.
Principal is …
an initial amount of money received by a borrower
Amortization of a loan is …
an amount of money equal to the principal lent to a borrower, which is repaid to the lender at a later time
The interest of a loan is …
an additional sum of money paid to the lender at the time of amortization
The two types of loans are ___________ and ____________ . Which is used depends on ______.
Single-payment loans
Loans repaid by annuities
how the borrower repays the principal
Single-payment loans are …
Loans that require the repayment of the entire principal
sum at the end of its duration and the interests is paid either periodically or not.
Loans repaid by annuities are …
loans where the principal and interest of the loan is repaid by an annuity but the interest is calculated on the unpaid balance.
Single-payment loans are also known as …
bullet loans
Bullet loans are ….
loans that does not amortize over time and must be repaid with a single large payment (also called a balloon payment) at the end of the term of the loan.
A single large payment is also called a
balloon payment
We can differentiate two types of single-payment loans: __________ and _______________.
- When the interests are also paid at the end of the term of the loan (as part of the bullet payment)
- When the interests are paid periodically during the term of the loan.
Single-payment loans are typically ________ loans.
short-term loans
We use the single payment method for _________
bonds and other fixed-income securities.
Two amortization methods are ….
- Single Payment Method
2. Annuities
In the single payment method, for bullet payment, Cn = -C0(1+i)^n
True
** negative because we pay
In the single payment method, for the loans where the interest is paid during the term of the loan, I = C0i% and Cn = C0(1+i)
True
Annuity-amortized loans are normally just called …
Amortized loans
Amortized loans are …
loans with scheduled periodic payments or installments that are composed of two parts:
- the principal repayment
- the interest payment
“As” is called the
principal payment
The two parts of an installment are …
- Principal Payment
2. Interest Payment
The principal repayment (𝑨𝒕) is …
the amount of money the borrower pays to reduce the outstanding loan amount.
The interest payment (𝑰𝒕) is …
the amount of money calculated over the outstanding loan amount, which the borrower pays in concept of interests.
The total amount paid by the lender or installment (𝒂𝒕), is
the sum of the principal repayment and the interest payment.
At = at-It
True because at = At + It
𝑪𝒕 is …
the outstanding loan amount (the unpaid balance) at the moment t.
𝑪𝟎 is …
the amount of money the borrower receives from the lender (the principal of the loan).
True or False, when all the principal repayments are paid, the loan is fully amortized.
True
Because a loan is fully amortized when all the principal repayments are made, the sum of all the principal repayments is equal to the principal.
True
𝐶0 = ∑𝐴t
We can compute the unpaid balance at a given moment, Ct (that is, the part of the principal which has not been paid yet) as the unpaid balance at the previous period minus
the principal repayment of the period.
True
𝐶𝑡 = 𝐶𝑡−1 − 𝐴t = debt yesterday - debt today
the unpaid balance at a given moment t is called
the part of the principal which has not been paid yet
The unpaid balance at a given moment t can be also calculated as the principal of the loan minus all the paid principal repayments or the sum of all the principal repayments to be paid in the future
True
C𝑡 = 𝐶0 − ∑𝐴t
or,
Ct =∑C
In addition to the principal repayments, the borrower must pay the interests.
True
In annuity amortized loans, the interest paid are calculated as the rate of interest of the loan multiplied by the unpaid balance at the beginning of the period
True
It = i%*Ct-1
The interest payments can be paid with the same periodicity as the principal payments, or more frequently than the interest payments.
True
In annuity amortized loans, the interest is always computed over the unpaid balance.
True
In loans with equal frequency for interest and principal payments …
we pay the principal payment and the interest
In annuity amortized loans, if we pay the interest more frequently than principal payments,
We pay the interest one period and the interest + principal payment the other period.
The rule of financial equivalence states that …
The unpaid balance of a loan at any moment k can be calculated as the sum of the discounted value of all the pending installments.
𝑪𝒌 = ∑𝒂𝒕/(1+i)^t, where t = k+1
𝑪𝒌 = ∑𝒂𝒕/(1+i)^t, where t = k+1 is called
The rule of financial equivalence
Principal repayments, As =
as - Is
Unpaid balance, Cs =
debt yesterday - debt today
Cs-1 - As
Repaid balance, Ms =
Ms = C0 - Cs or ∑As
Usually, loans are amortized by immediate annuities, i.e., the payment of the principal starts in the next period to the collection of the principal by the lender.
True
Although loans are amortized by immediate annuities, it is possible to agree to have the payment of the principal paid by a deferred annuity.
True
Immediate annuities means …
the payment of the principal starts in the next period to the collection of the principal by the lender.
The period between the granting of the loan
and the first payment of principal is called …
the grace period.
The two types of graces periods are:
- Interest-only grace period
In an interest-only grace period,
the borrower only pays interests during the grace period
In a no-payment grace period,
the borrower will make no payment during the grace period, but the interests will be compounding.
In a non-payment grace period, Cc-1 =
𝐶𝑐−1 = 𝐶0 (1 + 𝑖)^𝑐−1
You are paying interest on the new compounded amount, and C0 = the new compounded amount
In interest-only grace period, 𝐶𝑛 =
Cn-1 * i%
The installments of an annuity-amortized loan can be computed following different payment plans.
True
The most commonly used plans in an annuity-amortized loan are the following:
- Equal principal payment (AKA straight line method)
- Equal installment loans (AKA French method)
- Varying-installment loans
- Anticipated interest method (less common in Spain)
- Sinking fund method (less common in Spain)
In the straight line method,
all the installments are composed of a constant principal payment 𝐴𝑡 = 𝐴 ∀𝑡 , plus the interest
on the unpaid balance.
Equal principal payment is also known as
(AKA straight line amortization)
Equal installment loans are also known as
(AKA French method)
