How to Calculate If Refinancing is Worth It | Homejourney
Refinancing is worth it if your monthly savings exceed total costs within 2-3 years, typically saving S$10,000+ over the loan term for a S$1M loan dropping from 3.5% to 3.0%. This cluster article dives into the exact calculations Singapore homeowners need, building on our pillar guide to Singapore home loans. At Homejourney, we prioritize your safety with verified rates and multi-bank comparisons to ensure transparent decisions.
Refinancing Fundamentals in Singapore
Refinancing means switching your home loan to a new lender for better rates or terms, unlike repricing which stays with your current bank. For HDB or private properties, this is key when to refinance mortgage after your lock-in period ends, avoiding penalties of 1.5% on prepaid amounts[1][2]. Homejourney helps you compare rates from DBS, OCBC, UOB, HSBC, Standard Chartered, Maybank, and more at https://www.homejourney.sg/bank-rates.
In Singapore, most loans tie to SORA (Singapore Overnight Rate Average), the MAS benchmark replacing SOR since 2024. Current 3M compounded SORA hovers around 3.0-3.2% plus bank margins of 0.7-1.0% p.a.[1]. An interest rate trigger of 0.5% drop often justifies refinancing, but calculate first using our eligibility tool at https://www.homejourney.sg/bank-rates#calculator.
Step-by-Step: How to Calculate If Refinancing is Worth It
Follow these actionable steps for precise analysis:
- Input Current Loan Details: Note outstanding principal (e.g., S$800,000), rate (e.g., 3.5%), tenure left (25 years), monthly payment (S$4,000).
- Find New Rates: Check Homejourney for best offers, e.g., UOB's 3M SORA +0.70% Year 1 (est. 3.7% total, dropping to 3.2% later)[1]. New payment: S$3,700 (use DBS calculator style[8]).
- Calculate Monthly Savings: S$300/month (S$4,000 - S$3,700).
- Tally Costs: Legal fees S$2,000-3,000 (often subsidized), valuation S$500-1,500, admin S$200, possible clawback if early[2]. Total: S$4,000.
- Break-Even Point: Costs / Savings = S$4,000 / S$300 = 13 months. If under 24-36 months, it's worth it.

Real Singapore Example: HDB Flat in Tampines
For a S$500,000 HDB loan at 2.6% (HDB rate) vs bank refinance to SORA+0.8% (3.4%), savings might be minimal due to low HDB rates. But for private condo in Orchard (S$1.2M loan, 3.8% to 3.2%), monthly save S$450, costs S$5,000, break-even 11 months—worth it. Track via our SORA tool on Homejourney.
Hidden Costs and Break-Even Analysis
Best time refinance aligns with lock-in period end (2-3 years standard)[2]. Factor clawback (prepaid interest refund loss, up to 0.5 months interest), discharge fees S$1,500. Banks like Citibank offer calculators showing net savings[3].
Total costs average S$3,000-6,000 for loans over S$450k, with cashback S$2,000 from UOB[1]. Net cost: S$2,000-4,000. Over 20 years, 0.5% rate cut saves S$50,000+ interest.
