Financing ideas for your quote

Cash option: pay ₱300,000 upfront, then keep about ₱3,500/month in bill savings with no loan payment.
During the loan, expect about ₱6,464/month out-of-pocket after bill savings (₱9,964 payment minus ₱3,500 savings).
After the 36-month loan ends, the full ₱3,500/month savings stays in your pocket.
Cash payback reference: about 7.1 years if savings stay near ₱3,500/month.
Zero-down financing improves cash flow now, but total interest increases your long-term cost.
