    Standard amortization. Lump sum applied to principal in month one.

    Where the lump sum can come from

    • Employer SLR contribution under IRC Section 127, up to $5,250/year, tax-free
    • Year-end performance bonus redirected to principal
    • Federal or state tax refund
    • Sign-on bonus as part of a job offer
    • Inheritance, gift, or asset sale

    How the calculator works

    Standard monthly amortization. Each month: interest = balance × (APR ÷ 12); principal portion = payment − interest; new balance = old balance − principal. The lump sum is applied to principal in month one, instantly reducing the balance against which interest accrues.
