บ้านราคา 3.XX ล้านบาท ต้องผ่อนเดือนละเท่าไหร่ พร้อมสูตร + ตาราง + แผนเตรียมกู้

How much would the monthly payments be for a house costing 3.XX million baht? Also include the formula, a table, and a plan for loan preparation.

Apr 24

"A house worth over 3 million baht... the installments must be brutal." This is a common belief that makes many people hesitate, even though a 3.XX million baht house doesn't always mean monthly payments of 20,000 baht. This is because the "installment amount" depends on 4 main variables:

(1) Actual loan amount

(2) Loan period

(3) Promotional interest rate for the first 1-3 years

(4) Interest rate after the promotional period

And in 2026, many banks still have initial promotional interest rates that can genuinely make installments "feel light," especially for those who get a long loan period of 35–40 years (e.g., GH Bank has products that allow loan periods of up to 40 years under age conditions).

This article will help you answer questions without guessing.

How much "should" you pay for a 3.XX million baht house?
Why can some people really pay 9,000–10,000 baht for the first 3 years?
What happens from year 4 onwards (and how to prepare for it)?
A practical checklist for loan preparation for "merchants/freelancers"

1) Straight Answer: How much are the monthly payments for a 3.XX million baht house?

To ensure a fair discussion, let's establish some "central assumptions" first:

House price 3.30 million baht (a middle example for 3.XX)
Down payment 0–10% (depending on LTV/bank conditions)
Loan period 30 years vs 40 years
Interest is divided into 2 periods: Promotional period (first 1–3 years) and after the promotional period

Table A: Payments during the "promotional period" (installments will seem light due to low interest rates)

The figures are "estimates" for planning purposes (actual installments depend on the bank/product/promotion at the time of application).

Case 1: Promotional interest rate of approximately 2.00% and a long loan period of 40 years

If a 3.30 million baht house, "10% down payment" → Loan amount ~ 2.97 million
- Monthly payments approximately 8,900–9,100 baht/month (similar to what you mentioned)
If borrowing the full 3.30 million → Monthly payments approximately 9,900–10,100 baht/month

Simplified summary:

The figures "9,000–10,000" often result from a very low initial interest rate + long loan period (e.g., 40 years) +/or some down payment.

Table B: After the promotional period (this is the "real deal" that needs planning)

After years 3–4, interest rates often shift to floating rates based on MRR/MLR, etc., causing installments to jump if not refinanced/retained.

Example of a "loan interest structure" with actual reference data:
GH Bank's "Home for You" project in 2026 specifies interest rates in periods, such as year 1, years 2–5, and year 6 onwards. And GH Bank's MRR (effective December 25, 2025) is 6.195%. Therefore, in this example, years 2–5 are MRR-2.00% ≈ 4.195% and year 6+ is MRR-0.75% ≈ 5.445% (calculated from the announced MRR).

Overall to remember:

During the promotional period, installments might be in the "low tens of thousands/under ten thousand."
But after the promotional period, if the interest rate returns to around 5–6%, installments for a house in the high 3 million range could increase to the mid-to-high tens of thousands (depending on the loan amount and remaining loan term).

2) Why do some people "under 30" pay less?

It's not because banks have a special fondness for them, but because the longer the loan term, the lower the installment.
For example, GH Bank's product specifies a maximum loan term of 40 years, with a condition that "the borrower's age plus the loan term must not exceed..."
Therefore, younger individuals have the opportunity to "extend the contract longer," which reduces their monthly payments.

But remember:

Lower installments = often higher total interest over the life of the loan (because you pay longer)
The smart strategy is to "borrow long to qualify," then aim to refinance/make extra payments as your income grows.

3) LTV in 2026: Why some periods allow "low down payments"

Important news for homebuyers: The Bank of Thailand (BOT) has a measure to temporarily relax LTV criteria, setting the LTV ceiling at 100% in some cases, and specifying a period for loan contracts entered into from May 1, 2025 to June 30, 2026.

In plain language:

In some situations, you might not need as large a down payment as during stricter periods.
However, "high LTV" does not mean "easy loan approval," as banks primarily consider repayment ability.

4) What do banks look for when approving loans? (Especially for merchants/freelancers)

A term you should know is DSR (Debt Service Ratio), or "debt burden to income."
The BOT has a document summarizing the standard DSR calculation, explaining the principle of using the total monthly debt obligations (existing debt + new debt) divided by gross income.

And broadly, the BOT explains the concept of Responsible Lending, stating that there are no fixed criteria/specific ceilings, but financial institutions should primarily assess debt repayment ability.

What do banks want to see most from "merchants"?

To be frank: banks are not against self-employed individuals, but they are against "unprovable income."

A checklist that significantly strengthens a loan application:

1. Consistent bank statements for 6–12 months

Income comes in "lump sums" and continuously.
Not irregular deposits withdrawn completely on the same day.

2. Separate personal vs. business accounts

Business account for sales income
Personal account for expenses
This method significantly helps banks "read actual income."

3. Proof of supplementary income (if any)

Transfer slips/platform sales reports/receipts
Tax documents/commercial registration (the more you have, the more credible)

4. Clearly understand other installment debts

Because DSR counts "all debts," including credit cards, personal loans, car loans, etc.

5) Quick installment calculation formula (for self-assessment before deciding)

If you don't want to use a calculator every time, use this "rule of thumb" instead:

Very low interest (approx. 2%) + long loan term of 40 years
→ For a 3.XX million baht house, installments "might be seen" around 9,000–11,000 (depending on down payment/loan amount)
Moderate interest (approx. 4–5%) + loan term of 30 years
→ Could increase to around 15,000–20,000+
High interest (approx. 6%) + loan term of 30 years
→ Easily moves to around 18,000–24,000

The key point is:
Don't plan solely based on "years 1–3" installments.
Plan for "year 4 onwards" as well, and use years 1–3 as a period to build credit for refinancing.

6) What to do in Year 4? The "avoiding installment jumps" strategy that most people miss

Here's a safe and practical plan for a 3.XX million baht house:

Plan for the first 3 years: Make yourself "attractive for refinancing"

Pay on time every installment (because payment history affects consideration)
If you have extra cash: Make extra principal payments sometimes to reduce the debt faster.
Don't create new debt that causes your DSR to spike (credit cards/personal loans/new car).

Entering "late Year 3 – Year 4": Do these 2 things

1. Check refinancing/retention conditions (switch banks or ask for an interest rate reduction from the same bank).

2. Calculate a realistic installment amount that you can afford at 5–6% interest.
If you can still manage that level of installment, you won't stress even if the bank doesn't approve refinancing on the first attempt.

7) Comparing with "8–9 thousand baht rent": Which is more worthwhile?

This sentence you wrote is "very impactful" and should be expanded with reasons:

Rent 8–9 thousand baht/month
Pros: Flexible, easy to move, no lump sum needed
Cons: Payments go on indefinitely, no asset built in your name
House installments (even if close to rent during promotional period)
Pros: Money paid "converts to an asset" and has potential for appreciation
Caveats: Must manage interest after the promotional period and hidden costs (transfer fees, taxes, insurance, maintenance)

The unvarnished conclusion:
Paying for a house is not difficult if you plan to survive "after the promotional period" from day one.

8) Checklist for being "ready to buy a 3.XX million baht house" in 30 days (for merchants)

If you want banks to "nod in approval" when they review your application, do these 7 things:

1. Keep your main income in "one account" to clearly show revenue.

2. Maintain a good bank statement for at least 6 months (12 months is even better if possible).

3. Pay off high-interest debts first (credit cards/personal loans).

4. Reduce monthly installment amounts to leave room for house payments.

5. Save at least 3–6 months of your target installment amount as an emergency fund.

6. Prepare business documents: commercial registration/sales records/taxes (as available).

7. Get a "Pre-approve" before making a reservation to greatly reduce risk and anxiety.

Summary

Layer 1: Installments during the promotional period (makes starting possible)
Layer 2: Installments after the promotional period (makes continuing stress-free)

And if you are a merchant, what helps you get a loan is not saying "I have good income," but rather income proof that the bank believes.
