Frequently Asked Questions
How is my maximum HELOC calculated?
We multiply your home value by the LTV limit you choose (75–90%), subtract your remaining mortgage balance, and show the result as your available credit line.
What's the difference between the draw period and repayment period?
During the draw period (typically 10 years) you borrow and pay interest only. In the repayment period you pay principal plus interest each month until the balance is paid off.
What are rate shock scenarios?
HELOCs have variable rates tied to Prime. The +1% and +2% scenarios show exactly how your monthly payment changes if rates rise, so you can borrow safely.
Does the app work offline and keep my data private?
Yes. All calculations run 100% on your device. No account, no uploads, no internet required.
How accurate are the results?
The app uses standard lender formulas for LTV, interest-only and amortized payments. Real rates, limits and fees vary by lender, so treat results as planning estimates.
Is the app free?
Yes — free to download and use. An optional Pro upgrade removes ads and unlocks unlimited saved scenarios.
