FAQs
How much difference do extra repayments make?
Even moderate recurring extra repayments can materially reduce both total interest and payoff years, especially earlier in the loan.
Should I do extra repayments or keep cash in offset?
Extra repayments reduce principal directly, while offset preserves liquidity. Compare both based on flexibility needs and account fees.
Can I use this for weekly and fortnightly plans?
Yes. The calculator supports monthly, fortnightly and weekly repayment frequencies for scenario comparison.
