Mortgage Recast vs Refinance Comparison
Compare mortgage recasting and refinancing side by side to see which strategy saves you more money. Enter your loan details below to get an instant comparison of monthly payments, total costs, and a clear verdict on which option wins.
A mortgage recast vs refinance comparison helps homeowners decide between two strategies for lowering their monthly payment. Recasting reduces your principal with a lump-sum payment while keeping your existing loan terms, whereas refinancing replaces your entire mortgage with a new one at a potentially lower rate. This free calculator shows you which option saves more based on your specific numbers.
How Mortgage Recasting Works
Mortgage recasting (also called re-amortization) involves making a large lump-sum payment toward your principal balance, then having your lender recalculate your monthly payment based on the reduced balance over the remaining term. Your interest rate and loan term stay the same. According to the Consumer Financial Protection Bureau (CFPB), most conventional loan servicers offer recasting for a small fee of $150 to $300. The process typically takes 1 to 2 weeks with no credit check, appraisal, or income verification required.
Recasting works best when you have a large sum available (inheritance, bonus, home sale proceeds) and your current interest rate is already competitive. The lump sum directly reduces your principal, which means you also pay less total interest over the life of the loan.
How Refinancing Works
Refinancing replaces your existing mortgage with an entirely new loan, potentially with a different interest rate, term length, and lender. According to Freddie Mac research, the average borrower who refinanced saved approximately $2,800 per year in mortgage payments during the 2020-2021 rate environment. The process involves a full application, credit check, home appraisal, and underwriting, taking 30 to 45 days to close. Closing costs typically range from 2% to 5% of the loan amount.
Refinancing makes the most sense when interest rates have dropped significantly (0.75% or more below your current rate), you want to switch from an adjustable-rate to a fixed-rate mortgage, or you need to change your loan term. The rate savings can offset the higher closing costs over time.
Recast vs Refinance: Key Differences
| Factor | Recast | Refinance |
| Interest Rate | Stays the same | Can change (lower or higher) |
| Loan Term | Stays the same | Resets (new 15, 20, or 30-year term) |
| Upfront Cost | $150-$300 fee + lump sum | 2-5% closing costs |
| Credit Check | Not required | Required (hard pull) |
| Timeline | 1-2 weeks | 30-45 days |
| Eligible Loans | Most conventional | All loan types |
When to Choose Each Option
Choose recasting when your current rate is already competitive, you have a large lump sum available, you want to avoid credit checks and lengthy paperwork, or you want to lower payments quickly with minimal fees. Recasting is also ideal if you recently purchased a home and received proceeds from selling your previous property.
Choose refinancing when interest rates have dropped significantly (0.75% or more), you want to switch from an ARM to a fixed rate, you need to change your loan term (e.g., 30-year to 15-year), or you want to do a cash-out refinance. Refinancing also resets the amortization schedule, which can be advantageous if you plan to stay long-term.
In some cases, doing both is optimal: recast now for immediate payment relief, then refinance later if rates drop further. The lump-sum payment reduces your principal regardless of which path you take next. Last updated: May 2026.
