Should You Refinance Your Mortgage? SORA Rates, Optimal Tenure & Savings Calculator for Singapore Homeowners 2026
Every 2 to 3 years, your mortgage lock-in period expires and a familiar question pops into your head: should I refinance? In Singapore, most homeowners can save thousands by switching banks — but only if the interest savings outweigh the legal fees, mortgage duty, and administrative hassle. This guide walks through SORA rate mechanics, how to calculate the exact break-even point for refinancing, and why your remaining tenure matters more than you think.
Understanding SORA Mortgage Rates in Singapore 2026 — How the 3-Month Compounded SORA Benchmark Determines What You Pay Every Month
SORA stands for Singapore Overnight Rate Average. It replaced the old SIBOR and SOR benchmarks in 2024 as the standard interest rate reference for all new Singapore dollar loans. When your banker quotes you a rate like “3M SORA + 0.60%,” they mean the 3-month compounded SORA (published daily by MAS) plus a fixed spread of 0.60% set by the bank.
As of mid-2026, the 3-month compounded SORA hovers around 2.3% to 2.6%, which means your all-in mortgage rate is typically 2.9% to 3.5% depending on the bank spread. This is lower than the 2023-2024 peak when SORA hit 3.7% and all-in rates touched 4.5%, but still higher than the near-zero rates of 2020-2021 when homeowners were paying under 1.5%.
The key thing about SORA-linked loans is that your monthly payment changes every time SORA resets — typically every 3 months for 3M SORA packages or every month for 1M SORA packages. When SORA drops by 0.5%, your monthly payment on a S$500,000 loan decreases by roughly S$145. When it rises by the same amount, your payment jumps by the same. The SORA Mortgage Calculator lets you input any SORA rate and spread to see exactly what your monthly payment would be at different rate scenarios.
Fixed-Rate vs Floating-Rate SORA Packages — Which Is Better in 2026?
Some banks offer fixed-rate packages for 2 to 5 years (typically 2.8% to 3.2% in mid-2026), while SORA floating rates are currently around 2.9% to 3.3%. The difference is small right now, which makes fixed rates attractive for risk-averse borrowers who value predictable monthly payments. However, if you expect SORA to decline further (as some economists predict in late 2026 or 2027), a floating SORA package gives you the benefit of lower payments as rates drop.
Understanding Mortgage Refinancing Savings in Singapore 2026 — When Switching Banks Actually Makes Financial Sense
Refinancing means moving your existing mortgage from one bank to another to get a lower interest rate. In Singapore, this typically happens every 2 to 3 years when the lock-in period expires. During the lock-in period, you face a penalty of 1% to 1.5% of the outstanding loan if you refinance early — which almost always wipes out any interest savings.
Once your lock-in expires, the question becomes simple arithmetic: will the interest savings from the lower rate exceed the cost of switching? The switching costs are predictable: legal fees (S$2,000 to S$3,000 for both outgoing and incoming conveyancing), mortgage duty (S$500), valuation fee (S$300 to S$500), and possibly a fire insurance policy from the new bank (S$100 to S$300). In total, expect S$3,000 to S$4,500 to refinance.
Here is a quick mental shortcut: if the rate difference between your current rate and the new rate is at least 0.3% to 0.5%, refinancing usually makes sense on a loan balance above S$400,000 with at least 15 years remaining. Below that threshold, the interest savings over the new 2-3 year lock-in period may not cover the switching costs. The Refinancing Savings Calculator does this exact comparison — plug in your current rate, the new rate, your outstanding balance, and it shows the net savings after all switching costs.
Understanding Mortgage Tenure Optimisation in Singapore 2026 — How Shortening or Extending Your Loan Period Affects Total Cost
Tenure is the total number of years over which you repay your mortgage. In Singapore, the maximum is 30 years for bank loans (subject to the age limit where tenure + age cannot exceed 65 for full LTV) and 25 years for HDB concessionary loans. Every year you add to your tenure reduces your monthly payment but increases the total interest you pay over the life of the loan.
The difference is dramatic. A S$700,000 loan at 3% over 20 years costs S$3,882 per month with total interest of S$231,700. The same loan over 30 years costs S$2,951 per month — S$931 less — but total interest balloons to S$362,400. That extra S$130,700 in interest is the price you pay for 10 years of lower monthly payments. For many Singaporeans, the monthly cash flow relief is worth it, especially during their early career years when income is lower. But as your salary grows, switching to a shorter tenure can save a significant amount.
When you refinance is the perfect opportunity to also re-evaluate your tenure. Many homeowners who started with a 30-year loan at age 30 find that by age 38 (when they refinance for the third time), they can comfortably afford the higher payment of a 20-year tenure. The Mortgage Tenure Calculator shows you exactly how different tenures affect your monthly payment and total interest, side by side.
How These 3 Mortgage Calculators Work — Refinancing Break-Even, SORA Rate Scenarios and Tenure Comparison for Singapore Homeowners
The Refinancing Savings Calculator compares your current mortgage against a new offer. Enter your outstanding balance, current rate, new rate, remaining tenure, and switching costs. It computes: monthly payment savings, total interest savings over the remaining tenure, net savings after switching costs, and the break-even month (when cumulative savings exceed switching costs). If the net savings is negative, the calculator clearly tells you refinancing is not worth it.
The SORA Mortgage Calculator shows how SORA rate movements affect your mortgage. Enter your loan amount, SORA rate, bank spread, and tenure. It computes the monthly instalment and lets you run “what-if” scenarios: what happens if SORA rises by 0.5%? What about 1%? This stress-testing is essential before choosing between a fixed-rate and floating-rate package.
The Mortgage Tenure Calculator compares different loan tenures side by side. Enter your loan amount and interest rate, and it generates a comparison table showing monthly payment, total interest, and total amount paid for 15, 20, 25, and 30-year tenures. It also shows the age limit check: whether your chosen tenure stays within the 65-year or 75-year age cap.
3 Real Refinancing Examples for Singapore — HDB Owner, Condo Upgrader and Large Loan Holder
Example 1: HDB Owner Refinancing from HDB Loan to Bank Loan — S$380,000 Balance
Ah Huat took an HDB concessionary loan at 2.6% when he bought his 5-room flat 8 years ago. His outstanding balance is S$380,000 with 17 years remaining. DBS is offering 3M SORA + 0.55% = 2.85% with a 2-year lock-in.
The new bank rate is actually higher than the HDB rate. Moving from HDB to a bank loan only makes sense if the bank rate is significantly lower. In mid-2026, the HDB 2.6% rate is competitive — hold your HDB loan unless SORA drops below 2.0%. Also note: once you leave an HDB loan, you cannot go back to it.
Example 2: Condo Owner Lock-In Expiring — S$650,000 Balance, 22 Years Left
Priya took a SORA + 0.80% package 3 years ago. Her current all-in rate is 3.50%. OCBC is offering SORA + 0.55% = 2.95% with a 2-year lock-in. Outstanding balance S$650,000.
The net saving is S$868 over 2 years after costs — modest but positive. If Priya also shortens her tenure from 22 to 20 years during the refinance, she saves an additional S$18,000+ in lifetime interest. Use the Refinancing Calculator to run your own numbers.
Example 3: Large Loan Holder — S$1.2 Million Balance, 25 Years Left
Rajan has a S$1.2 million outstanding condo mortgage at 3.80% (his old SIBOR package). UOB is offering 3M SORA + 0.58% = 2.98% with a 3-year lock-in.
On a large loan with a significant rate gap, refinancing is a no-brainer. The S$14,360 net savings pays back the switching costs in just 8 months. For loans above S$1 million, even a 0.5% rate improvement generates meaningful savings. Check the Refinancing Calculator and compare multiple bank offers.
3 Expert Tips for Mortgage Refinancing and SORA Management in Singapore
Set a Calendar Reminder 3 Months Before Lock-In Expires
Banks know most homeowners forget about their lock-in expiry. After the lock-in ends, many banks revert you to a higher “board rate” of 4% to 5%. Set a reminder 3 months before your lock-in expires to start shopping for new packages. Banks typically take 6 to 8 weeks to process a refinancing application, so starting early gives you time to compare at least 3 offers. Use the SORA Calculator to compare packages at different spreads.
Repricing Is Cheaper Than Refinancing — Check Your Own Bank First
Before refinancing to another bank, ask your current bank about repricing. Repricing means staying with the same bank but switching to a newer, cheaper package. The cost is typically S$500 to S$800 (just an admin fee — no legal costs, no mortgage duty, no valuation). If your bank offers a rate within 0.1% to 0.2% of the best competitor, repricing is almost always better because the switching cost difference (S$800 vs S$3,500) offsets the slightly higher rate.
Use the Refinancing Window to Shorten Your Tenure
When you refinance, you have the option to adjust your tenure. If your income has grown since you first took the loan, consider shortening the tenure by 3 to 5 years. On a S$600,000 loan at 3%, shortening from 25 to 20 years saves S$42,000 in total interest while increasing your monthly payment by only S$330. The Tenure Calculator shows you the exact trade-off, and the savings compound because you are now on the lower rate from the new bank.
16 Frequently Asked Questions About Mortgage Refinancing and SORA Rates in Singapore
What is SORA and how does it affect my mortgage rate in Singapore?
SORA is the Singapore Overnight Rate Average, published daily by MAS. It replaced SIBOR and SOR as the benchmark for Singapore dollar loans. Your mortgage rate is SORA plus a bank-set spread (typically 0.50% to 0.85%). When SORA rises, your mortgage payment increases. When SORA falls, your payment decreases.
When is the best time to refinance my mortgage in Singapore?
The best time to refinance is when your lock-in period has expired and the rate difference between your current rate and the best available rate is at least 0.3% to 0.5%. Start shopping 3 months before your lock-in expires to allow time for processing.
How much does it cost to refinance a mortgage in Singapore?
Typical refinancing costs are S$3,000 to S$4,500 including: legal fees for outgoing bank (S$800-S$1,200), legal fees for incoming bank (S$1,500-S$2,000 but often subsidised), mortgage duty (S$500), valuation fee (S$300-S$500), and fire insurance (S$100-S$300).
What is the difference between refinancing and repricing?
Refinancing means moving your loan to a different bank. It involves full legal conveyancing and costs S$3,000+. Repricing means staying with your current bank but switching to a different rate package. It costs only S$500-S$800 with no legal process. Always check repricing options before refinancing externally.
Can I refinance during my lock-in period?
Yes, but you will pay a penalty of 1% to 1.5% of the outstanding loan amount. On a S$600,000 loan, that is S$6,000 to S$9,000. This penalty almost always exceeds any interest savings. Wait until the lock-in expires unless you are facing extreme financial hardship.
Should I switch from HDB loan to bank loan?
Only if the bank rate is significantly lower than the HDB 2.6% rate. In mid-2026, most bank rates are 2.9% to 3.5%, so the HDB rate is competitive. Also note: once you leave an HDB concessionary loan, you cannot return to it. HDB loans also allow CPF usage with no restrictions and have no lock-in penalties.
How many times can I refinance my mortgage?
There is no limit. Most Singapore homeowners refinance every 2 to 3 years when their lock-in period expires. Over a 25-year mortgage, that could be 8 to 12 refinancing events. Each time costs S$3,000 to S$4,500 in fees, so factor this into your lifetime mortgage cost.
What is the 3-month compounded SORA rate today?
SORA rates are published daily by MAS. As of mid-2026, the 3-month compounded SORA is approximately 2.3% to 2.6%. Check the latest rate on the MAS website or use our SORA Mortgage Calculator which lets you input any rate for comparison.
Is a fixed-rate or floating SORA mortgage better in 2026?
In mid-2026, fixed rates (2.8%-3.2%) and SORA floating rates (2.9%-3.3%) are very close. Fixed rates suit risk-averse borrowers who want predictable payments. SORA floating rates suit those who believe rates will decline further. If rates are expected to stay flat or fall, SORA floating is usually cheaper over the lock-in period.
What is a board rate and why should I avoid it?
The board rate is the bank internal reference rate, typically 4% to 5.25%. Banks revert your mortgage to the board rate after your lock-in period expires if you do not actively refinance or reprice. Always switch to a new package before your lock-in expires to avoid paying the expensive board rate.
Does refinancing affect my LTV or TDSR?
Refinancing an existing loan to a new bank at the same or lower balance does not trigger fresh LTV or TDSR checks, as long as you are not increasing the loan amount. If you want to cash out (equity term loan), TDSR and LTV will be reassessed based on current rules.
Can I change my mortgage tenure when refinancing?
Yes. Refinancing is an opportunity to adjust your tenure. You can shorten it (to save on total interest) or extend it (to lower monthly payments). The new tenure is subject to the age limit: tenure plus your age cannot exceed 65 for full LTV or 75 for reduced LTV.
What documents do I need to refinance in Singapore?
You typically need: last 3 months payslips, latest income tax Notice of Assessment, CPF contribution statement, existing loan statement showing outstanding balance and rate, and property title deed. Self-employed borrowers may need 2 years of financial statements.
How long does the refinancing process take?
The typical timeline is 6 to 10 weeks from application to completion. This includes: bank approval (1-2 weeks), valuation (1 week), legal conveyancing (3-4 weeks), and CPF transfer (1-2 weeks). Start the process at least 2 months before your lock-in expires.
Do I need to pay mortgage duty again when refinancing?
Yes. Each new mortgage document requires fresh mortgage duty of 0.4% of the loan amount, capped at S$500. This is an unavoidable cost of refinancing and applies every time you switch banks. Over multiple refinancing cycles, the cumulative mortgage duty adds up.
What happens to my CPF usage when I refinance to a new bank?
Your CPF OA housing usage transfers to the new bank. The CPF Board processes the transfer as part of the refinancing conveyancing. Your accrued interest obligation continues to accumulate regardless of which bank holds the mortgage. There is no additional CPF charge for refinancing.
