Offset Account Calculator (ADHD-Friendly)

See how your offset account saves you money without complex math. Simple calculator for ADHD brains who want clarity, not spreadsheets.

You've heard offset accounts save money, but what does that actually mean for you? This calculator makes it concrete. Enter your loan amount, how much you keep in offset, and your interest rate. Instantly see how much you're saving every single month by having that money sitting there. No complex explanations about how interest is calculated — just the real dollar savings you're getting. Think of your offset balance as money that's working silently in the background, reducing what you owe interest on. The more you keep there, the less you pay the bank. This calculator shows you exactly how much that's worth, so you can decide if keeping money in offset beats other options.

FAQ

How does an offset account work?

Money in your offset account reduces the loan balance that interest is calculated on. If you have $50,000 in offset on a $400,000 loan, you pay interest on $350,000.

Is an offset account worth it?

Offset accounts are valuable if you maintain a significant balance. The interest savings often exceed what you'd earn in a regular savings account, especially in high-rate environments.

100% offset vs partial offset?

A 100% offset account reduces interest dollar-for-dollar. Partial offset accounts only count a portion of your balance against the loan.

Is offset really worth it?

If you maintain a solid balance, yes. This calculator shows you the exact dollar value of your offset — if the savings look good, it's working.
