Ever thought about refinancing to save cash? My pal John was paying 7.0 percent on his $250,000 loan, but in 2026 with rates at 6.5 percent, he refinanced and saved $120 a month. That’s $43,200 over 30 years. A refinance calculator is your tool to see if it’s worth it. At MortgageTune.com, we’ve made this tool to help you compare old and new loans, especially for zero down refinances. This guide covers how to use it, why it’s crucial, and tips to refinance. Let’s jump in.
What Is a Refinance Calculator?
A refinance calculator estimates savings when you replace your current loan with a new one. It factors in balance, rates, terms, and costs. In 2026, with rates at 6.5 percent, it shows if dropping from 7.0 percent saves $100,000.
Why Use It in 2026? Prices up 3.5 percent per Redfin, refinances up 20 percent per Freddie Mac. It helps zero down buyers see if VA refinance cuts payments.
How It Works: Enter current balance ($250,000), rate (7.0 percent), term (25 years), new rate (6.5 percent), term (30 years), costs ($5,000). Get monthly/total savings.
