What is velocity banking?

Velocity banking is a debt payoff strategy that uses a revolving line of credit, such as a HELOC, along with your income and monthly cash flow. Income is deposited into the line of credit to lower the balance interest is calculated on, and periodic chunk payments reduce mortgage or loan principal.

Does velocity banking actually save money?

It depends on your cash flow, interest rates, loan terms, fees, and spending habits. This calculator compares velocity banking against traditional repayment using your own numbers so you can see which approach costs less.

Can I use a credit card instead of a HELOC?

Yes. The calculator supports any revolving line of credit, including credit cards, and models interest with the average daily balance method.

Is the velocity banking calculator free?

Yes, the calculator is free to use, requires no account, and saves your plans locally in your browser.

extra cost

With these numbers, chunking costs more than simply applying your cash flow directly. Try a lower line rate, a smaller fee, or a larger chunk.

When each debt clears

Chunks cascade to the next debt as soon as one is gone.
