Use advanced options to model realistic repayment structures:
- Down payment and balloon payment
- Compounding frequency and payment frequency (monthly, biweekly, weekly, daily, or lump sum)
- Payment timing comparison: ordinary annuity vs annuity due
How to calculate:
- Annuity loan: fixed periodic payment where each installment includes interest plus principal. Payment is based on principal, period rate, and number of periods.
- Lump-sum loan: single repayment at maturity. Future payment is estimated as principal grown by interest over the full term. To use this mode, open Advanced options and set Payment frequency to End of term (lump sum).
Typical use cases: compare lender offers, target a payment budget, estimate payoff period, or validate how payment structure changes the total repayment cost.
Loan Calculator FAQ
How do I calculate monthly loan payment?
Enter loan amount, interest rate, and loan term. The calculator uses an annuity-based repayment model by default and returns the periodic payment, total interest, and total amount paid.
What is the difference between annuity and lump-sum loan?
Annuity loans are repaid with regular installments over time. Lump-sum loans are repaid once at maturity. You can switch to lump-sum mode in Advanced options under Payment frequency.
How do down payment and balloon payment affect results?
A down payment reduces the financed principal. A balloon payment moves part of repayment to the end of the term. Both can lower regular payments but change total interest and repayment profile.
Can I generate an amortization schedule?
Yes. Use the Amortization Table button under the chart to view period-by-period principal, interest, payment amount, and ending balance, including yearly summaries.
