This guide is for young working adults in the Philippines—especially if you’re earning your first few salaries, paying bills, helping family, or simply trying to make “adult money decisions” with less stress. It’s also for breadwinners and practical planners who need to think about how one purchase can affect the rest of the month.
In real life, “big purchases” can feel heavier here because money often has multiple jobs: rent, groceries, commuting, family support, savings, and emergencies. Even when something feels “affordable,” it can still quietly squeeze your budget later.
This article isn’t here to tell you what to buy or what not to buy. The goal is simpler: help you understand the full cost of a purchase—beyond the price tag—so you can decide with clearer eyes and less regret.
What “true cost” really means
True cost is the total impact of a purchase on your money and your life—not just the amount you pay at checkout.
When people say, “Kaya ko naman,” they usually mean the sticker price fits their budget. But the sticker price is only the beginning. True cost includes:
- Time: How long you’ll use it, how long you’ll pay for it, and what it delays (like saving).
- Ongoing expenses: Data plans, fuel, maintenance, subscriptions, fees, repairs.
- Trade-offs: What you give up to afford it—less savings, smaller emergency buffer, postponed goals.
A simple way to think about it:
Sticker price = what you pay today
True cost = what it costs you over time
What counts as a “big purchase” for most Filipinos
A “big purchase” isn’t defined by a fixed peso amount. It depends on your income, responsibilities, and how stable your budget is.
For many Filipinos, common big purchases include:
- Phones (especially upgrades bought on installment)
- Laptops or tablets (for work, freelancing, school)
- Appliances (aircon, refrigerator, washing machine)
- Vehicles (motorcycle, car—often with ongoing costs)
- Travel (flights, accommodations, visas, daily spending)
- Home upgrades (furniture, repairs, essential replacements)
If you feel hesitant, that’s normal. Hesitation usually means you’re already thinking beyond the price tag—and that’s a good sign.
How to calculate the true cost step by step
Below is a practical method you can use for almost any purchase. You can do it on paper, in notes, or with a calculator.
Step 1: Start with the upfront cost
Write down everything you pay before you can use it comfortably, not just the main item.
Include:
- Item price
- Delivery fees
- Accessories that are realistically required (case, charger, bag, helmet)
- Setup costs (installation, initial supplies)
Example (Laptop):
- Laptop: ₱45,000
- Bag: ₱1,500
- External drive: ₱2,000
- Total upfront: ₱48,500
Step 2: List ongoing expenses (monthly or yearly)
Ask: “Once I own this, what does it make me pay regularly?”
Common ongoing costs:
- Subscriptions (cloud storage, apps)
- Data plan or load
- Maintenance (cleaning, servicing)
- Consumables (filters, ink, parts)
- Insurance (optional, but common for gadgets/vehicles)
Example (Phone):
- Extra data plan: ₱300/month
- Over 24 months: ₱7,200
Step 3: Add installment costs and fees (even if it says “0%”)
Installment can be useful—but “0%” doesn’t always mean “no extra cost.”
Look for:
- Processing fees
- Add-on “required” insurance
- Higher cash price vs promo price
- Missed discounts (cash discount you didn’t get)
Also consider the behavioral cost: installment can make it feel lighter, which can lead to overspending in other areas.
A helpful check:
- What is the total you will pay across all months?
- What does it do to your monthly cash flow?
Step 4: Estimate maintenance, repairs, and replacements
Many big purchases don’t fail on day one—they fail later, usually when you’re not ready.
Include:
- Warranty ends: what’s a realistic repair cost?
- Parts that wear out (battery replacement, tires, filters)
- Replacement cycle (how long until you need a new one?)
You don’t need perfect numbers. Even a conservative estimate helps you see the true picture.
Step 5: Consider time and opportunity cost (the part people skip)
Opportunity cost is what you could have done with the money instead.
This isn’t about guilt. It’s about clarity.
Ask:
- If I spend this now, what does it delay?
- Building an emergency fund
- Paying down debt
- Saving for a move, exam, trip, or family need
- If the item is on installment, how many months will it “sit” in my budget?
A simple way to make this real:
- “This purchase is equivalent to X months of saving ₱____.”
Example:
If you plan to save ₱5,000/month and the true cost is ₱50,000, that’s 10 months of savings.
Step 6: Calculate the “cost per month” and “cost per use”
This is where the true cost becomes easier to compare.
- Cost per month = True cost ÷ months of expected use
- Cost per use = True cost ÷ number of uses (rough estimate)
This helps answer:
- “Is this expensive because it’s overpriced, or because I won’t use it enough?”
Common things people forget to include
Here are the most common “missing pieces” that make people underestimate true cost:
- “0% installment” misunderstandings
People forget to check the total paid, fees, or missed discounts. - Accessories and add-ons
Chargers, cases, cables, bags, helmets, installation—small costs that add up. - Repairs after warranty
Phones, appliances, and vehicles often need maintenance after the warranty period. - Subscriptions that become permanent
“Trial” subscriptions can turn into monthly costs you forget to cancel. - Emotional justifications (“deserve ko ’to”)
It’s okay to buy something you want. But it helps to separate: - “I want this” (valid)
- “This is cheap” (might not be true)
- “This won’t affect me later” (often untrue)
A calm rule of thumb:
If you need to convince yourself it’s “small,” it may be a big purchase for your current budget. /h
Using tools to make the math clearer
If you want a quick way to organize these costs—especially the ones people forget—you can use Chichay’s True Cost Calculator to plug in upfront costs, ongoing expenses, and time-based costs in one place: Chichay’s True Cost Calculator.
Tools like this don’t make decisions for you. They simply make the trade-offs visible—so your decision is less based on vibes and more based on reality.

When this method may not be enough (limitations)
This guide helps you estimate true cost, but it won’t perfectly predict real life. Some things can change fast:
- Income changes (job shifts, freelance volatility, overtime)
- Emergencies (medical needs, home repairs, family obligations)
- Personal priorities (your “worth it” might be different from someone else’s)
Also: this is not professional financial advice. It’s a practical framework to help you think clearly and avoid common blind spots.
Final thoughts: making informed, pressure-free decisions
Big purchases don’t have to be scary. The goal isn’t to avoid spending—it’s to spend with fewer surprises.
When you calculate true cost, you give yourself something many people don’t have: a calm, realistic view of what a purchase actually means over time. That clarity can help you decide without pressure, without guilt, and without regret.
