Mortgage Refinance Examples With Calculations
Compare three mortgage refinance examples with payment changes, break-even months, five-year savings, remaining balances, and lifetime interest tradeoffs.
How should you use these Refinance Calculator examples?
These examples turn the Refinance Calculator inputs into complete scenarios with stated values, calculation steps, and interpreted results. Use them to check how the calculator behaves, compare your own situation with realistic cases, and identify which inputs have the greatest effect before relying on an estimate.
Three Mortgage Refinance Examples
These examples are calculated by the same tested engine used on the Refinance Calculator. Each example changes a meaningful loan decision so the payment, break-even, remaining-balance and lifetime-cost tradeoffs are easy to compare.
Example 1: Lower Rate With the Same Remaining Term
A borrower owes $300,000 at 6.5% with 25 years remaining. The new offer is 5.5% for 25 years with $6,000 in costs paid upfront and a five-year horizon.
| Current payment | $2,025.62 |
|---|---|
| Proposed payment | $1,842.26 |
| Monthly savings | $183.36 |
| Simple break-even | 33 months |
| Five-year net savings | $8,873.45 |
| Lifetime savings | $49,007.70 |
Because the terms are equal, the lower rate reduces both the payment and modeled lifetime cost. The five-year result measures only the selected holding period.
Example 2: Higher Payment With a Shorter Term
A $250,000 balance at 7% has 20 years remaining. The proposal is 6.25% for 15 years, with $5,000 in costs financed into the new balance.
| Current payment | $1,938.25 |
|---|---|
| Proposed payment | $2,186.43 |
| Monthly change | $248.18 increase |
| Simple break-even | Not reached |
| Five-year proposed balance | $194,729.82 |
| Lifetime savings | $71,622.27 |
The payment rises, so there is no simple payment break-even. The shorter term still produces a lower five-year balance and lower modeled lifetime borrowing cost.
Example 3: Lower Payment From Restarting at 30 Years
The same $250,000 current loan is compared with a 5.75%, 30-year refinance and $5,000 in upfront costs.
| Proposed payment | $1,458.93 |
|---|---|
| Monthly savings | $479.32 |
| Simple break-even | 11 months |
| Five-year net savings | $7,495.01 |
| Five-year proposed balance | $231,905.47 |
| Added lifetime cost | $65,036.21 |
The payment drops and costs are recovered quickly, but the longer term leaves a higher balance after five years and adds modeled lifetime cost.
Compare the Three Refinance Scenarios
| Scenario | Payment change | Break-even | Five-year savings | Lifetime savings |
|---|---|---|---|---|
| Same 25-year term | $183.36 lower | 33 months | $8,873.45 | $49,007.70 |
| Shorter 15-year term | $248.18 higher | Not reached | $6,020.89 | $71,622.27 |
| New 30-year term | $479.32 lower | 11 months | $7,495.01 | -$65,036.21 |
