At mortgage signing, the banker's final pitch is always the same: "Add MRTA and we'll cut your rate another 0.25%." Most people accept or refuse on the spot without ever seeing the real numbers. This guide unpacks MRTA completely — what it is, what it costs, whether the rate discount truly offsets the premium, and how much cash comes back if you refinance or pay off early.
MRTA (Mortgage Reducing Term Assurance) is term life insurance whose sum insured declines with your debt — full loan coverage in year one, then stepping down along a schedule tracking your remaining principal. If the borrower dies or is totally permanently disabled mid-loan, the insurer pays the covered balance directly to the bank; the house passes to heirs unencumbered.
Differences from ordinary life cover: the primary beneficiary is the bank (up to the debt), the sum insured shrinks rather than stays level, and premiums are usually paid once upfront — which makes cover-per-baht notably cheaper than level-sum policies.
The single premium depends on borrower age (older = pricier), gender, sum insured (full or partial) and coverage term. Rough figures for borrowers aged 30–35:
| Coverage structure | Premium (~% of loan) | On a 3M THB loan |
|---|---|---|
| 100% cover, full 30-year term | 5–7% | 150,000–210,000 |
| 100% cover, 15 years | 3–4.5% | 90,000–135,000 |
| 70% cover, 15 years | 2–3% | 60,000–90,000 |
| 50% cover, 10 years | 1.2–2% | 36,000–60,000 |
Banks often offer to roll the premium into the loan. It feels painless, but you're then paying interest on the premium for 30 years — a 150,000 THB premium can compound past 250,000 THB in total cost. If you buy MRTA, pay the premium in cash where possible.
Run the numbers: on a 3,000,000 THB, 30-year loan, a 0.25% discount over a 3-year promotional period saves roughly 22,000–23,000 THB in interest — while full MRTA costs 150,000+. The discount alone never pays for the premium. Don't buy MRTA to chase a promo rate; decide on protection value, and treat the discount as a bonus.
The exception: some banks discount for the entire loan life or price their packages very differently with and without MRTA. In those cases, request both offers in writing and compare total cost across the promotional period case by case.
Strongly consider: sole breadwinners, single borrowers with dependents, co-borrowers who couldn't carry the loan alone, and anyone with no life cover at all — for them, MRTA is the most targeted keep-the-house tool available.
Possibly unnecessary: singles without dependents (if the worst happens, the house is sold to settle the debt and nobody is stranded), people whose existing life cover already exceeds their debts, and those with liquid assets that could clear the loan outright.
The middle path that usually fits: insure 50–70% of the loan for the first 10–15 years — when principal is highest and the family most exposed. A decade in, the balance has fallen and finances have typically strengthened; the need fades naturally.
The least-known fact: single-premium MRTA has surrender value. If you close the loan early — selling, paying off, refinancing — you can surrender the policy for a partial refund per its schedule, larger in early years and shrinking over time. Surrendering a 30-year policy in year five might return roughly 30–50% of the premium depending on the insurer.
When refinancing, some insurers also allow re-assigning the beneficiary to the new bank, keeping your coverage alive without repurchasing at an older age. Before any refinance, call your insurer and ask what your policy allows — this is tens of thousands of baht people routinely forget.
No. Bank of Thailand rules prohibit tying insurance to loan approval. Banks may only incentivise via rate discounts. If you're pressured with "no MRTA, no approval", you can complain to the BOT's financial consumer protection centre.
Yes, when the coverage term is 10 years or longer — counted within the 100,000 THB/year life-premium allowance, usable only in the year you pay the single premium.
Split coverage by each person's share of the burden — 50/50 or income-weighted. The test: if one income disappears, the survivor must manage the remaining installments alone; each side's sum insured should close exactly that gap.
MRTA is neither a hidden fee nor a sales trick — it's house-protection for families that depend on the borrower's income. But nobody has to take the first full-coverage quote. Decide based on the people behind you, not the rate discount; start from 50–70% coverage over 10–15 years; pay the premium in cash rather than rolling it in; and remember it refunds at refinance.
