Refinance Calculator: Complete Guide to Mortgage Refinancing
What is Mortgage Refinancing?
Mortgage refinancing involves replacing your current home loan with a new one, typically to take advantage of better terms, lower interest rates, or to access home equity. It's essentially paying off your existing mortgage and starting fresh with new loan terms.
Types of Mortgage Refinancing
Rate-and-Term Refinance
- • Change interest rate
- • Modify loan term
- • No cash out
- • Lower monthly payments
- • Reduce total interest
Cash-Out Refinance
- • Borrow against home equity
- • Receive cash at closing
- • Higher loan amount
- • Fund home improvements
- • Consolidate debt
When to Consider Refinancing
- Interest Rates Drop: Generally beneficial if rates are 0.5-1% lower
- Credit Score Improved: Better credit may qualify you for lower rates
- Change Loan Terms: Switch from 30-year to 15-year or vice versa
- Remove PMI: If home value increased enough to eliminate PMI
- Access Home Equity: Cash-out refinance for major expenses
- Switch Loan Types: Convert from adjustable to fixed rate
Break-Even Analysis
The break-even point determines how long it takes to recover refinancing costs through monthly savings:
Break-Even Period = Total Refinancing Costs ÷ Monthly Payment Savings
If you plan to stay in your home longer than the break-even period, refinancing likely makes financial sense.
Refinancing Costs
| Cost Type | Typical Range | Description |
|---|---|---|
| Application Fee | $300-$500 | Processing the loan application |
| Appraisal Fee | $300-$700 | Professional home valuation |
| Title Insurance | $500-$1,500 | Protection against title issues |
| Origination Fee | 0.5%-1% of loan | Lender processing fee |
| Total Closing Costs | 2%-5% of loan | All fees and costs combined |
Cash-Out Refinance Considerations
Cash-out refinancing allows you to borrow against your home equity, but consider these factors:
- Loan-to-Value (LTV): Most lenders limit cash-out to 80% LTV
- Higher Rates: Cash-out refis typically have slightly higher rates
- Tax Implications: Interest may not be deductible unless used for home improvements
- Risk Assessment: You're increasing your mortgage debt
- Alternative Options: Consider HELOC or home equity loan

Frequently Asked Questions
How much can I save by refinancing?
Savings depend on rate reduction, loan balance, and how long you keep the loan. Even a 0.5% rate reduction can save thousands over the loan term.
How long does refinancing take?
Typically 30-45 days from application to closing, though it can vary based on lender, property type, and loan complexity.
Can I refinance with bad credit?
It's possible but challenging. You may face higher rates, limited options, or need to improve credit first. FHA streamline refinancing may be an option for existing FHA borrowers.
Should I refinance into a shorter term?
Shorter terms typically offer lower rates and significant interest savings but higher monthly payments. Consider your budget and financial goals.
