Plan your next step with Signet’s Calculators — and go deeper with Banzai®
Whether you’re buying a car, preparing for a mortgage, or dialing in a payoff plan, our calculators help you test ideas before you make a move. Then, Banzai’s interactive coaches turn those numbers into real-world skills.
Auto: Use Auto Payment to estimate monthly payments and Auto Affordability to find a target price that fits your budget.
Mortgage: Start with Mortgage Payment and Home Affordability. If you’re comparing refinancing, try Refi Break-Even to see how long savings take to catch up with costs.
Where to find them
Visit our Banzai Calculators page. Each tool opens in a new tab and lets you adjust the numbers in real time.
Plug in your numbers — then move the sliders
Enter price, down payment, loan term, and estimated rate. Then adjust the sliders to see how your payment changes. Aim for a monthly number that leaves room for savings and your essentials.
Pro tip: Try a slightly higher rate to stress-test your budget. If it still works, you’re set up for success.
Want a lower payment? Increase the down payment or extend the term — then compare total interest paid so you understand the trade-offs.
Cross-check with today’s Signet rates
After you get a ballpark payment, compare it to our current rates to tighten your estimate.
Rates and terms are subject to change and may vary based on creditworthiness. Membership required.
