How to calculate your mobile loan
Mobile loan is a popular option for Thais who want to buy a new smartphone without paying a lot of money. This calculator supports 3. The main forms used in Thailand: 0% campaign, loan through mobile operators, and credit card loan.
1. Campaign 0% (no interest)
The simplest formula:
- Repayment. = Price of the phone - down payment.
- - You're a witch. = Repayment ÷ Months
The 0% campaign is available at Apple Store, Samsung Store, mobile operators (AIS, True, DTAC), supermarkets and some bank credit cards during the promotion period.
2. Mobile phone loan (AIS/True/Dtac)
Mobile operators offer special price when subscribing to monthly packages. What to pay has 2 parts:
- Massager. = (mobile price − down payment) ÷ number of months (usually 0%)
- Package Costs = Monthly fees for the duration of the contract.
- Real monthly payments. = Massager + Package
3. Credit card payments (with interest).
The flat rate formula used by the Thai banks:
- Repayment. = Price of the phone - down payment.
- Total Interest = Repayment x Interest per month x Months
- - You're a witch. = (payment + total interest) ÷ number of months
Calculation example
iPhone loan price 45,900 baht through credit card 10 month interest 0.8% per month:
- Repayment: 45,900 baht
- Total interest: 45,900 × 0.8% × 10 = 3,672 baht
- Total repayment: 45,900 + 3,672 = 49,572 baht
- Draw: 49,572 ÷ 10 = 4,957.20 baht/month
The interest rate on mobile phones in Thailand is 2026.
- Campaign 0%: No interest (Apple Store, Samsung, Mobile)
- Credit card: 0.7-0.9% per month (approximately 8-10% per year)
- Personal credit: 1-2% per month (approximately 12-25% per year)
The phone loan trick.
- Always choose the 0% campaign first because it pays no interest.
- Compare cash price to installment price — some stores add 0% interest compensation to the machine price.
- Mobile massages combined with other debt burden should not exceed 40% of income.
- If you're paying through a mobile company, check the contract-wide package, it might be more expensive than buying a blank.
- Credit card installments 0%, the longest, the best value. But if there is interest Short installments, pay less
