Determine if refinancing your mortgage will save you money.

Quick Refinance Analysis

Step 1: Calculate Monthly Savings

Your Current Loan Your New Loan
Remaining balance: $_____ Same balance
Current rate: ____% New rate: ____%
Current payment: $_____ New payment: $_____
Monthly savings $_____

Step 2: Calculate Break-Even

Break-Even = Closing Costs ÷ Monthly Savings

Closing Costs Monthly Savings Break-Even
$3,000 $150 20 months
$4,000 $150 27 months
$5,000 $200 25 months
$6,000 $200 30 months
$8,000 $300 27 months
$10,000 $400 25 months

Refinance Savings Examples

Example 1: Rate Drop of 1%

Current: $300,000 at 7.50%, 27 years remaining

Scenario Current Refinance @ 6.50%
Rate 7.50% 6.50%
Monthly payment $2,098 $1,896
Monthly savings $202
Closing costs $6,000
Break-even 30 months

If staying 30+ months: Refinance makes sense

Example 2: Rate Drop of 0.5%

Current: $350,000 at 7.25%, 25 years remaining

Scenario Current Refinance @ 6.75%
Rate 7.25% 6.75%
Monthly payment $2,387 $2,269
Monthly savings $118
Closing costs $6,500
Break-even 55 months

If staying 55+ months: Worth considering

Example 3: Shortening Term

Current: $250,000 at 7.00%, 30-year, 25 years remaining

Scenario Current 30-yr New 15-yr @ 6.25%
Rate 7.00% 6.25%
Monthly payment $1,663 $2,142
Total interest remaining $248,900 $135,570
Interest savings $113,330
Payoff 25 years 15 years

Higher payment but massive long-term savings

When Refinancing Makes Sense

Good Reasons to Refinance

Situation Benefit
Rate dropped 0.75%+ Lower payments & interest
Shorter term available Pay off faster
Remove PMI Eliminate insurance premium
ARM to fixed Rate stability
Cash-out for home improvement May be tax-deductible

Think Twice About Refinancing

Situation Why
Rate drop < 0.5% May not offset costs
Moving in 1-2 years Won’t break even
Resetting to 30 years Extends payoff date
High closing costs Longer break-even

Costs to Factor In

Cost Typical Range
Origination fee 0.5-1% of loan
Appraisal $400-$700
Title insurance $500-$1,500
Other closing costs $1,000-$3,000
Total typical 2-5% of loan

No-Closing-Cost Option

Feature Standard Refinance No Closing Cost
Closing costs $6,000 paid upfront $0 upfront
Interest rate 6.50% 6.875%
Monthly payment $1,896 $1,970
Better if staying 4+ years Under 3 years

Refinance Decision Flowchart

  1. Rate difference 0.75%+?

    • Yes → Continue
    • No → Probably not worth it
  2. Planning to stay past break-even?

    • Yes → Continue
    • No → Consider no-cost refinance or skip
  3. Can afford closing costs?

    • Yes → Standard refinance
    • No → Roll into loan or no-cost option
  4. Resetting term significantly?

    • No → Good to proceed
    • Yes, but much lower rate → May still save
    • Yes, similar rate → Reconsider
