A mortgage is the largest financial commitment most people ever make, and small differences — a quarter-point in rate, a few thousand in closing costs, a 30-year versus a 15-year term — add up to tens of thousands of dollars over time. Mortgage Draw exists to make those trade-offs easy to see. Each calculator turns the standard mortgage math into a clear answer in seconds, and each one is paired with a plain-English explanation of how it works, a worked example, and answers to the questions people most commonly ask.
Thinking about refinancing?
Start with the refinance calculator to compare your current loan with a new rate and term. It shows your new payment, your monthly savings, the difference in lifetime interest, and how long it takes to recover your closing costs. Zero in on payback time with the break-even calculator, test whether paying discount points is worth it, and estimate your fees with the closing cost calculator.
Need to tap your home equity?
Compare the three main ways to turn equity into cash: a cash-out refinance that replaces your mortgage with a larger one, a HELOC that works like a revolving credit line, or a fixed-rate home equity loan. Homeowners 62 and older can also estimate proceeds with the reverse mortgage calculator.
Buying a home?
If you are eligible for a government-backed loan, the VA loan calculator and USDA loan calculator handle their special funding and guarantee fees and the $0-down options. Building or bridging between homes? See the construction loan and bridge loan calculators.
A note on accuracy. Our tools use the same amortization and fee formulas lenders use, but they produce estimates for general information only — not financial, tax or legal advice. Rates, fees and eligibility rules change, and your real numbers depend on your lender and circumstances. Always confirm with a licensed mortgage professional before you commit.

Are these mortgage calculators free?
Yes. Every calculator on Mortgage Draw is completely free, works instantly in your browser, and never asks you to sign up or share personal information. Nothing you type is uploaded or stored.
How accurate are the results?
Each tool uses the standard, well-established financial formulas (loan amortization, interest-only payments, loan-to-value, funding and guarantee fees, and so on). They produce reliable estimates, but your real numbers depend on your lender, credit, location and the final terms you are offered. Always confirm with a licensed professional before deciding.
Do the calculators include taxes and insurance?
Most of our payment calculators focus on principal and interest (and any loan-specific fees, like the VA funding fee or USDA annual fee). Property taxes and homeowners insurance vary widely by location and are usually collected separately in an escrow account, so we call them out rather than guess at them.
Which calculator should I start with?
If you have a mortgage and rates have dropped, start with the refinance calculator. If you need cash from your home, compare the cash-out refinance and HELOC tools. Buying with a government-backed loan? Try the VA or USDA calculators.
Is Mortgage Draw a lender?
No. We are an independent, educational resource that publishes free calculators and plain-English guides. We do not originate loans, take applications, or sell your data. Our content is for general information only and is not financial advice.
