Long-term loan with reduced interest.
A term loan uses a reducing balance interest calculation, so that the interest rate is the same every month, but the ratio of principal and interest changes each month.
PMT formula
The fraction = P × [r(1+r)ⁿ] / [(1+r)ⁿ - 1] Where P = principal, r = interest rate per instalment, n = total number of instalments
Difference in frequency of payment.
Monthly: The lowest total interest, because the principal decreases the fastest.
Quarterly: It's a good business for quarterly revenue.
Annual: The highest total interest rate, slow down, suitable for farming.
example
Loan 5,000,000 baht Interest 6.5% per year Repayment 10 per year:
Monthly: instalment 56,722 baht/month Total interest 1,806,640 baht
Quarterly: instalment 172,008 baht/quarter. Total interest slightly higher.
Frequently asked questions
What is a term loan?
Long-term loans are loans with a fixed repayment date, from 1 years and up, with reduced balance interest, equal to the amount of the loan, for the purchase of fixed assets, business expansion, or large investments.
How is quarterly or yearly payment better than monthly?
Quarterly or annual payments are suitable for businesses with seasonal income, such as agriculture, tourism, and can better manage cash flow, but the total interest is usually higher than monthly payments because the principal decreases slower.
Does prepayment save interest?
Yes, early principal payments reduce the balance of the debt, reduce interest in the next instalment, and save a lot of interest, but you should check for prepayment penalties (usually between 1-3% of the amount paid early).
How long can a long-term business loan last?
General long-term business loans maximum 10-15 years for fixed assets such as machinery, buildings. Home loans maximum 30 years. Loans for new investment may have a grace period 1-2 years prior to the beginning of principal payments.
Installments and interest are numbers for preliminary screening of plans. Before actually applying, you should compare rates, fees, and conditions from service providers.
Calculated based on the principal, rate and term you enter.
This does not include certain types of fees, insurance or specific promotional conditions.
The total installment should not put pressure on monthly cash flow.
