How to Refinance Your Mortgage and Save Thousands
Refinancing your mortgage can save you tens of thousands of dollars over the life of your loan " — but it's not always the right move. Here's when refinancing makes sense, how to shop for the best rate, and how to calculate whether the savings justify the closing costs.
When Refinancing Makes Sense
The general rule: refinancing is worth it when you can lower your interest rate by at least 0.75% to 1% and plan to stay in the home long enough to recoup the closing costs. Here are the most common reasons to refinance:
- To get a lower interest rate. If rates have dropped at least 1% since you got your current mortgage, refinancing can significantly reduce your monthly payment and total interest paid.
- To shorten your loan term. Refinancing from a 30-year to a 15-year mortgage can save you enormous amounts in interest, though your monthly payment increases.
- To remove PMI. If your home has increased in value and you now have 20%+ equity, you can refinance to remove private mortgage insurance (PMI), saving $100-$300/month.
- To switch from an ARM to a fixed rate. If you have an adjustable-rate mortgage and expect rates to rise, refinancing into a fixed rate provides payment stability.
- To cash out equity. A cash-out refinance lets you borrow against your home's equity for major expenses (home improvements, debt consolidation). This should be used cautiously.
The Refinancing Break-Even Calculation
Before refinancing, calculate your break-even point " — the number of months it takes for your monthly savings to cover the closing costs:
| Example Calculation | Amount |
|---|---|
| Current monthly payment | $1,870 |
| New monthly payment after refinance | $1,620 |
| Monthly savings | $250 |
| Refinance closing costs | $4,000 |
| Break-even point | 16 months |
If you plan to stay in the home for at least 16 months (the break-even point), refinancing saves you money. If you plan to move in 12 months, refinancing loses money.
How to Shop for the Best Refinance Rate
- Check your credit score. The higher your score, the lower your rate. If your score has improved since you got your original mortgage, you may qualify for a better rate.
- Shop at least 3-5 lenders. Rates vary significantly between lenders. Get quotes from your current bank, a credit union, and at least 2-3 online lenders.
- Compare APR, not just interest rate. APR includes closing costs and fees, giving you a more accurate comparison of the total cost of each loan.
- Ask about no-closing-cost options. Some lenders offer no-closing-cost refinances by charging a slightly higher interest rate. This makes sense if you plan to sell or refinance again within 3-5 years.
- Lock your rate. Once you've chosen a lender, lock in your rate. Rate locks typically last 30-60 days. If rates drop further during this period, some lenders offer a float-down option.
Refinancing Costs to Expect
- Application fee: $75-$300
- Origination fee: 0.5%-1.5% of the loan amount
- Appraisal fee: $300-$500
- Title search and insurance: $700-$1,500
- Recording fees: $50-$250
- Total closing costs: Typically 2-5% of the loan amount
On a $300,000 mortgage, expect to pay $6,000-$15,000 in closing costs. These can sometimes be rolled into the loan amount, but this increases your total debt.
- You plan to move within 2-3 years (you won't recoup closing costs)
- Your credit score has dropped since getting the original mortgage
- You're extending your loan term (e.g., resetting a 15-year mortgage to 30 years) without a clear financial reason
- You're cashing out equity for non-essential spending
