Interest Rates sa Pilipinas: Flat vs Diminishing + APR Calculator
Alamin kung paano talaga gumagana ang interest rates. Ang pag-unawa dito ang makakatipid sa iyo ng libu-libong piso sa loan mo.
⚠️ Bakit Importante Itong Alamin?
Maraming Pilipino ang naloloko sa "murang" interest rate na 1% o 2% per month. Pag kinompute mo, ito pala ay 24% per year! Ang artikulong ito ay tuturuan ka kung paano basahin ang tunay na presyo ng pautang.
Ano ang Interest Rate?
Ang interest rate ay ang bayad na binabayaran mo sa lender para sa paggamit ng kanilang pera. Isipin mo itong "upa" ng pera—habang tumatagal na hawak mo ang pera, mas maraming upa ang babayaran mo.
Sa Pilipinas, may dalawang pangunahing uri ng interest computation:
- Flat Rate - Nakapirmi ang interest base sa original amount
- Diminishing Balance - Bumababa ang interest base sa natitira pang utang
Flat Rate: Ang Pinaka-Common (at Pinaka-Mahal)
Sa flat rate system, ang interest ay kinukompute base sa buong halaga ng loan mula umpisa hanggang dulo. Hindi ito bumababa kahit nagbabayad ka na.
📌 Halimbawa: ₱50,000 Loan, 2% Flat Rate per Month, 12 Months
Step 1: Compute total interest
Interest = ₱50,000 × 2% × 12 months = ₱12,000
Step 2: Add to principal
Total amount = ₱50,000 + ₱12,000 = ₱62,000
Step 3: Divide by number of months
Monthly payment = ₱62,000 ÷ 12 = ₱5,166.67
💡 Pansin:
Kahit bumaba na ang utang mo sa ₱10,000 sa last 2 months, ang interest mo ay base pa rin sa ₱50,000. Kaya mas mahal ang flat rate!
Diminishing Balance: Ang Mas Makatarungan
Sa diminishing balance (o reducing balance), ang interest ay base sa natitira pang principal. Habang nagbabayad ka, bumababa ang principal, kaya bumababa rin ang interest mo.
📌 Halimbawa: ₱50,000 Loan, 2% Diminishing Balance per Month, 12 Months
Sample computation ng first 3 months:
| Month | Opening Balance | Interest (2%) | Principal | Total Payment | Remaining |
|---|---|---|---|---|---|
| 1 | ₱50,000 | ₱1,000 | ₱4,167 | ₱5,167 | ₱45,833 |
| 2 | ₱45,833 | ₱917 | ₱4,250 | ₱5,167 | ₱41,583 |
| 3 | ₱41,583 | ₱832 | ₱4,335 | ₱5,167 | ₱37,248 |
| Total (12 months): | ₱6,500* | ₱50,000 | ₱56,500 | ₱0 | |
*Approximate total interest
💰 Tipid:
Total interest: ₱6,500 lang vs ₱12,000 sa flat rate. Nakatipid ka ng ₱5,500!
Flat Rate vs Diminishing Balance: Side-by-Side
| Feature | Flat Rate | Diminishing Balance |
|---|---|---|
| Interest base | Original loan amount (nakapirmi) | Remaining balance (bumababa) |
| Total interest (₱50k, 2%, 12 mos) | ₱12,000 | ₱6,500 |
| Monthly payment | Pareho hanggang dulo | Pareho rin (pero mas mababa ang total) |
| Computation | Madali (basic multiplication) | Medyo komplikado (amortization) |
| Common sa | Lending apps, salary loans | Banks, housing loans |
| Mas makatarungan? | ❌ Hindi | ✅ Oo |
APR at EIR: Ang Tunay na Interest Rate
Dahil sa magkaibang computation methods, mahirap icompare ang loans. Kaya ginagamit ang:
- APR (Annual Percentage Rate) - Yearly rate including ALL fees (processing, insurance, etc.)
- EIR (Effective Interest Rate) - Actual rate na binabayaran mo considering compounding
🧮 Paano I-convert ang Monthly Rate to APR?
Scenario: Lending app nag-offer ng "2% per month"
Simple Annual Rate (Flat):
2% × 12 months = 24% per year
Effective Interest Rate (Compounded):
EIR = (1 + 0.02)^12 - 1 = 26.82% per year
With ₱500 Processing Fee (APR):
APR ≈ 27-28% (depends on loan amount)
⚠️ Alerto!
Kapag sinabi ng lender "1% per month lang," ang totoo niyan ay 12-13% per year! Laging tanungin ang APR o annual rate para makita ang tunay na presyo.
Mga Halimbawa: Real Loan Scenarios
Scenario 1: Lending App (₱10,000, 3 months)
Alok: "5% interest per month flat rate, no processing fee"
Principal: ₱10,000
Interest: ₱10,000 × 5% × 3 = ₱1,500
Total to pay: ₱11,500
Monthly: ₱11,500 ÷ 3 = ₱3,833.33
APR: ~60% per year 🚨
Scenario 2: Salary Loan (₱50,000, 24 months)
Alok: "1.5% per month diminishing, ₱1,000 processing fee"
Principal: ₱50,000
Processing fee: ₱1,000 (one-time)
Monthly payment: ~₱2,396 (via loan calculator)
Total paid: ₱2,396 × 24 = ₱57,504
Total interest + fee: ₱8,504
APR: ~19-20% per year ✅ Mas reasonable
Scenario 3: Bank Personal Loan (₱200,000, 36 months)
Alok: "14% per annum diminishing, ₱3,500 processing fee"
Principal: ₱200,000
Processing fee: ₱3,500
Monthly interest rate: 14% ÷ 12 = 1.167% per month
Monthly payment: ~₱6,836
Total paid: ₱6,836 × 36 = ₱246,096
Total interest + fee: ₱49,596
APR: ~15.5% per year (including fees)
Paano Icompare ang Iba't Ibang Loans?
✅ 5-Step Comparison Guide
- 1 Tanungin ang APR - Ito ang pinaka-important number. Huwag lang tignan ang monthly rate.
- 2 I-list LAHAT ng fees - Processing, insurance, documentary stamp, late payment penalty, etc.
- 3 Compute total amount to pay - Monthly payment × number of months + all fees
- 4 Check kung flat o diminishing - Diminishing is almost always better for long-term loans
- 5 Use online calculators - Huwag umasa sa mental math lang. Verify using tools.
Red Flags: Iwasan ang Mga Ito! 🚩
🚨 Hindi malinaw ang interest computation
Kapag ayaw sabihin ng lender kung flat o diminishing, o kung magkano ang APR - red flag yan!
🚨 APR na sobrang taas (>100% per year)
5-10% per month flat = 60-120% APR. Loan shark levels na yan. BSP recommends max 60% APR.
🚨 Hidden fees sa gitna ng loan
May "account maintenance fee" na bigla na lang lilitaw sa billing. Lahat ng fees dapat disclosed upfront.
🚨 "Too good to be true" rates
0.5% per month? Check kung may hidden fees, o baka scam. Walang libreng lunch sa lending.

Mga Madalas Itanong (FAQs)
❓ Mas mabuti ba ang 2% per month flat o 24% per year diminishing?
Diminishing is better! 24% per year diminishing is roughly equivalent to 1% per month on remaining balance.
Yan ay mas mura kesa 2% flat (which is 24% per year on ORIGINAL amount). Sa ₱50k loan, 12 months:
• 2% flat = ₱12,000 interest
• 24% diminishing = ~₱7,000 interest
Mas nakatipid ka ng ₱5,000!
❓ Paano ko malalaman kung ano ang tunay na APR ng loan ko?
Tanungin mo directly ang lender - required sila ng BSP na i-disclose yan. Kung ayaw nila sabihin, compute mo manually using online APR calculator. Kailangan mo ng: principal amount, monthly payment, loan term, at lahat ng fees. I-input yan sa calculator para makuha ang APR. Kung sobrang taas (>60% per year), mag-isip ka muna bago kumuha.
❓ Bakit iba ang monthly payment ko sa expected ko based sa advertised rate?
Common yan dahil sa mga hidden charges: processing fee (deducted upfront pero kasama sa loan amount), insurance premium, documentary stamp tax, o service charge. Example: ₱10k loan, pero binawas ang ₱500 fee - natanggap mo lang ₱9,500 pero ₱10k ang babayaran mo with interest. Kaya laging tanungin ang "Net proceeds" o actual amount na matatanggap mo.
❓ Legal ba ang 5% per month interest rate sa Pilipinas?
Technically walang maximum interest rate cap sa Pilipinas (removed na yung Usury Law sa 1983). PERO may "unconscionable" rates na pwedeng i-challenge sa korte. BSP recommends na hindi dapat lumagpas ng 60% APR para sa consumer loans. 5% per month flat = 60% per year, so borderline na yan. 5% per month compounded = 79% APR - sobra na yan. Choose lenders with responsible rates (banks usually 12-36% APR).
❓ Pwede ba akong humingi ng amortization schedule sa lender?
Oo, karapatan mo yan! According to BSP regulations, lenders must provide borrowers with clear information about the loan, including an amortization schedule kung hingin mo. Ang schedule na yan ay nagpapakita ng breakdown per month: magkano ang napupunta sa principal, magkano sa interest, at magkano ang remaining balance. Kung tumangging magbigay ang lender, red flag yan - baka may itinatago.
