How to use this calculator
- Enter the purchase amount you plan to put on installment.
- Choose the term, such as 6, 12 or 24 months.
- Pick the interest type: 0% interest, add-on rate per month, or annual rate per year, and enter the rate if it is not 0%.
- Add any one-time processing fee your bank charges.
- Read your monthly payment and the extra cost compared with paying in full, then try a shorter term to see how the cost changes.
How do credit card installments work?
A credit card installment splits one purchase into equal monthly payments. Some banks offer 0% plans on selected merchants, while others charge an add-on rate on the full amount or an annual rate on the remaining balance. The headline rate rarely tells the whole story, so the total you pay is the number to compare.
This calculator shows your monthly payment, total payments, one-time fee and the extra cost compared with paying cash. Use it to compare a 0% plan with a plan that has a fee, or to see why a long term costs more in total even when the monthly payment looks small.
Before you decide, check BDO, BPI, Mastercard and Visa offers for installment promos, and use the voucher stacking calculator to lower the price you finance.
How installment cost is calculated
- 0% plans: your monthly payment is the purchase amount divided by the number of months, plus any processing fee.
- Add-on rate: interest equals the amount times the monthly rate times the number of months, added up front and split evenly across the months.
- Annual rate: payments follow a diminishing balance, where interest is charged on what you still owe each month.
- The extra cost is your total payments plus any fee, minus the purchase amount. Banks can differ in how they apply fees and rounding, so check your card terms.
Tips to save more
- Lower the price first with vouchers, then finance the smaller amount.
- Prefer 0% plans without a processing fee when your budget allows.
- Choose the shortest term whose monthly payment you can pay comfortably.
- Never let installments stack until they use up more than a small share of your take-home pay.
