Loan payment anatomy
Cash received, fee wedge, interest arc, principal core, and balloon marker
The payment structure separates proceeds from financed balance and shows how fees and a balloon alter the apparent rate and repayment profile.

How to quote
Enter proceeds and fees exactly as the lender discloses them
- Use the amount you request before fees.
- Separate financed and withheld fees.
- Enter any balloon explicitly.
- Do not treat optional extra principal as required payment.
Payment method
Net proceeds can be lower than financed debt
When a fee is withheld, the borrower receives less cash than the face amount. When financed, the fee also accrues interest.
The effective-cost result compares all modeled borrower cash with actual proceeds received.
Calculation method
Convert loan terms into financed principal, payment, and effective cash cost
The origination fee is split between financed and upfront portions. The amortizing payment solves for the entered balloon, while extra principal is simulated separately to estimate earlier payoff.

Payment anatomy
What the monthly payment hides
Proceeds, fees, interest, principal, and balloon obligations are tracked separately.
Cash received
—Funds available after the upfront portion of the origination fee.
Financed balance
—Debt that actually begins accruing interest.
Effective cost
—Modeled cash paid above net proceeds.
Decision takeaway: Compare offers on net proceeds and total cash paid, not payment alone.
Practical applications
Decisions this calculator is designed to support
Fee withheld from proceeds
A lender deducts part of the origination fee before funding.
What the result clarifies: The model exposes the gap between requested amount and usable cash.
Extra-payment plan
A borrower intends to pay above the scheduled amount each month.
What the result clarifies: The checkpoint table shows whether the lender's structure produces meaningful principal acceleration.

Important note
Actual lender disclosures may use daily interest, different fee treatment, payment-date conventions, rounding, prepayment rules, insurance products, or late charges.
Personal Loan Payment Calculator FAQ
Why is financed balance above the requested amount?
The financed portion of the origination fee is added to principal.
Does the scheduled payment include extra principal?
No. The planned-payment result shows both amounts together.
How is a balloon handled?
It is discounted into the payment formula and remains due at the end unless extra payments retire it sooner.
