What is {primary_keyword}?

{primary_keyword} is a mortgage option that lets you make a lump‑sum payment toward the principal and then have the lender recalculate (recast) your monthly payment based on the reduced balance while keeping the original loan term.

Homeowners who receive a bonus, inheritance, or simply want to lower their monthly outflow often consider a {primary_keyword}.

Common misconceptions include thinking a {primary_keyword} shortens the loan term (it usually does not) or that it eliminates interest entirely (it only reduces it).

{primary_keyword} Formula and Mathematical Explanation

The core formula recalculates the monthly payment after a lump‑sum principal reduction:

New Payment = (Remaining Balance – Lump‑Sum) × r / (1 – (1 + r)^‑N)

Where:

  • r = monthly interest rate (annual rate ÷ 12 ÷ 100)
  • N = remaining number of payments (months)

Variables Table

Variable Meaning Unit Typical Range
Loan Balance Current principal $ $50,000 – $1,000,000
Interest Rate Annual nominal rate % 2.5 – 7.5
Remaining Months Months left on loan months 12 – 360
Lump‑Sum Recast amount $ $1,000 – $200,000

Practical Examples (Real-World Use Cases)

Example 1

Loan Balance: $300,000
Interest Rate: 4.5%
Remaining Months: 240
Lump‑Sum: $50,000

Original payment ≈ $1,897.00
New payment ≈ $1,632.00
Interest saved per month ≈ $265.00
Total interest saved ≈ $63,600 over the remaining term.

Example 2

Loan Balance: $200,000
Interest Rate: 3.8%
Remaining Months: 180
Lump‑Sum: $30,000

Original payment ≈ $1,470.00
New payment ≈ $1,306.00
Interest saved per month ≈ $164.00
Total interest saved ≈ $29,520.
