Can early loan repayments really save you money? Here's the financial truth
Making an early repayment on your loan might seem like a small move—but in the right context, it can result in huge interest savings. Especially in 2025, with middle-prepayment fees significantly reduced, this strategy becomes even more attractive. Let's dive into how this works, real-world examples, and when it's the smartest move.
Understanding the Core Benefit of Early Repayment
Loan interest is fundamentally calculated based on the remaining principal, interest rate, and time left. So, if you reduce the principal earlier in the loan term, you’re cutting off interest that would’ve been applied over years. This is especially effective in the early phase of a loan where monthly payments are mostly interest.
In 2025, for a fixed-rate loan at 3.5%, if you repay 10 million KRW in year 2, you can reduce your total interest by nearly 970,000 KRW. After accounting for a reduced prepayment fee (just 0.56%), your net savings could be around 920,000 KRW.
Prepayment Works Best in the First Few Years
Loan structures like equal principal and interest front-load interest payments. That means, during the first few years, your payments mostly go toward interest rather than the loan balance.
So, repaying during years 1 to 3 can yield double the savings compared to later years. After year 3, the benefit shrinks as a higher portion of payments are applied to the principal.
How 2025's Policy Shift Supercharged Prepayment Savings
As of January 13, 2025, prepayment penalties dropped dramatically. For example, fixed-rate mortgage fees went from 1.43% to 0.56%. On a 100 million KRW loan repaid within 3 years, that’s a drop from 4.2 million to 1.68 million KRW.
This incentivizes earlier repayments and unlocks potential for huge savings without the traditional penalty drag. Even variable-rate credit loans saw a fee cut to just 0.11%.
| Loan Type | Old Fee Rate | 2025 Fee | Example Saving (₩100M loan) |
|---|---|---|---|
| Fixed Mortgage | 1.4% | 0.56% | ₩4.2M → ₩1.68M |
| Variable Credit | 1.2% | 0.11% | ₩830K → ₩110K |
| Student Loans | Varies | Unchanged | Interest-first benefit |
Real-World Repayment Scenarios
Let’s break down real use cases. Suppose you borrowed ₩100M at 5% interest for 10 years. If you pay back ₩10M after 3 years, you can save between ₩600K and ₩900K in interest depending on the exact loan structure and payment mode.
A more aggressive international case from India shows even larger returns: A 25-year mortgage of 3 million rupees at 9.25% saw an 896,000 rupee interest drop with three small early repayments.
| Scenario | Repayment Amount/Timing | Total Interest | Saved | New EMI |
|---|---|---|---|---|
| ₩100M, 5%, 10Y | ₩10M after 3Y | ₩17.5M | ₩600K–₩900K | Reduced |
| ₹3M, 9.25%, 25Y | ₹600K (3x) | ₹4.7M → ₹3.8M | ₹896K | ₹25,691 → ₹20,497 |
| ₩100M, 3.5% | ₩10M after 2Y | ₩970K | ₩920K (net) | - |
Optimizing the Repayment Strategy
Target high-interest loans first—those above 5% yield the highest return from early repayment. Opt for equal principal methods when possible, as they reduce your interest faster.
Have over 10% surplus funds? Consider partial prepayment. It boosts your DTI ratio, helping you qualify for better loans in the future. Even small repayments can pay off—₩100K on a 5% loan saves ₩5K annually, while the same on a 1% loan only saves ₩1K.
What You Should Watch Out For
Prepayment isn’t always the right call. If your potential investment returns exceed loan interest (e.g., stock market yielding 7%+), you might be better off investing. Also, factor in each bank’s specific fee policies—some internet banks waive fees entirely after 3 years.
Don’t forget: Compare total costs—remaining interest + fees. And if interest rates are projected to fall, holding out may make more sense.
| Factor | Consideration |
|---|---|
| Prepayment Fee | Max 3 years; reduced in 2025 |
| Market Returns | Compare vs. interest rate |
| Rate Outlook | Wait if rates expected to drop |
| Loan Type | High-rate first, principal-heavy loans |
Takeaway: A Smart Move, If You Time It Right
Prepaying your loan is a tactical move—not just a financial chore. With 2025's regulatory shifts and lower prepayment fees, this strategy deserves your attention. If you’re holding onto spare funds, or about to lock in a new loan, run the numbers using your bank’s calculator. Every early won repaid today could be thousands saved tomorrow.
