The maximum loanable amount for a Pag-IBIG multi-purpose loan is typically up to 80% of your total accumulated savings. This includes your contributions, employer contributions, and the dividends earned. However, the final amount you can borrow may depend on your actual savings and your repayment capacity. It's best to check directly with Pag-IBIG or visit their official website for the most accurate and updated information regarding your specific situation.
