What is {primary_keyword}?

The {primary_keyword} is a specialized financial tool used by borrowers and lenders to determine the cost of replacing an existing loan with a portfolio of securities. This process, known as defeasance, allows the borrower to release the lien on the property while ensuring that the loan obligations are met through the cash flows generated by the securities.

Who should use the {primary_keyword}? Real‑estate investors, commercial loan holders, and financial advisors who need to evaluate the feasibility of defeasance will find this calculator essential.

Common misconceptions about the {primary_keyword} include the belief that defeasance eliminates all loan costs or that it is only applicable to small loans. In reality, the {primary_keyword} accounts for fees, yield differentials, and the time value of money.

{primary_keyword} Formula and Mathematical Explanation

The core formula behind the {primary_keyword} calculates the total defeasance cost as the present value of remaining loan payments discounted at the replacement security yield, plus any applicable fees.

Step‑by‑step derivation:

  1. Calculate the monthly payment of the existing loan using the coupon rate.
  2. Discount each future payment at the replacement security yield to obtain the present value.
  3. Sum the discounted payments and add the defeasance fee (a percentage of the principal).

Variables used in the {primary_keyword} are summarized below:

Variable Meaning Unit Typical Range
P Remaining Principal Balance Currency 1 M – 100 M
N Remaining Term (months) Months 12 – 360
c Current Loan Coupon Percent per annum 3 % – 8 %
y Replacement Security Yield Percent per annum 2 % – 6 %
f Defeasance Fee Percent of principal 0 % – 1 %

Practical Examples (Real‑World Use Cases)

Example 1

Assume a loan with a remaining principal of 5,000,000, 120 months left, a coupon of 5.5 %, a replacement yield of 4.2 %, and a defeasance fee of 0.5 %.

Using the {primary_keyword}, the monthly payment is calculated at 54,123. The present value of the remaining payments at the 4.2 % yield is 4,800,000. The fee amount is 25,000. The total defeasance cost therefore equals 4,825,000.

Interpretation: The borrower would need to set aside approximately 4.83 M in securities to fully defease the loan.

Example 2

Consider a larger loan of 20,000,000 with 240 months remaining, a coupon of 6 %, a replacement yield of 5 %, and a fee of 0.8 %.

The {primary_keyword} yields a monthly payment of 140,000, a present value of 18,500,000, and a fee amount of 160,000. The total defeasance cost is 18,660,000.

Interpretation: Defeasance would require roughly 18.66 M in a portfolio of securities, highlighting the impact of longer terms and higher fees.

Key Factors That Affect {primary_keyword} Results

  • Coupon Rate: Higher coupons increase monthly payments, raising the present value of remaining payments.
  • Replacement Yield: A higher yield reduces the present value of future payments, lowering the defeasance cost.
  • Remaining Term: Longer terms increase the number of discounted cash flows, affecting total cost.
  • Defeasance Fee: Even a small fee percentage can add significant absolute cost on large principals.
  • Market Volatility: Fluctuations in security yields can alter the discount rate used in the {primary_keyword}.
  • Tax Considerations: Tax treatment of the securities and fees may affect the net cost of defeasance.
