The True Cost of a Phone

Phone deals can cover service alone or include a handset. Some handset deals use a loan. Compare each payment once over the same period, including price changes and extras, and check the exit terms.

What a learner can do afterwards

  • Multiply a monthly cost by the contract length and compare it with buying outright plus a cheap plan
  • Explain what a contract locks you into and what an early exit costs
  • Name two extras that are easy to miss, such as insurance or data overage

Some deals include a handset; SIM-only plans do not. Borrowing to buy a handset means repaying a loan. Count each payment once: upfront charges, monthly bills and extras not included. Never add a handset price already included in the bills. At a fixed $18 monthly, 12 payments total $216. Separate insurance at a fixed $6 monthly for 12 months adds $72.

Try it together

With the same phone and service for 12 months, fixed prices and no extra fees, compare totals. At $34 monthly: 34 x 12 = $408. A $190 handset plus $11 monthly: $190 + (11 x 12) = $322. The difference is $86.

Check the term, price changes and exit rules. Early exit fees may apply; check the deal and local rights. For a fee per month left, multiply by the months left. Some plans charge for data over your allowance. Past bills help estimate data needs; allow for changes. Compare prices for service meeting those needs.

Good to know

Budget for extras: insurance or repairs.

Count all payments once, including price changes and extras. Compare costs over the same period for service that meets your needs.

Add up the phone deal

A SIM-only plan pays for service, not the phone. A phone deal may include repayments or a separate loan. Add the upfront amount, monthly payments and any uncovered extras. Count each payment once. Do not count the handset again if its cost is already in those payments.

At $25 a month, 24 payments come to $600. For changing prices, calculate each period separately. Compare identical phones and service for equal lengths of time. Buying the phone upfront and paying for a separate service plan could cost less overall than a free-handset deal. Compare the full totals.

Match a plan to your use

Look through earlier bills to see how much data, calling time and texting you use. Allow for changes you expect. Paying for an allowance you rarely use can waste money. Exceeding a small allowance can also cost extra, depending on the plan.

Check coverage and speed when comparing suitable plans. For an equal time period, total the upfront costs, monthly payments and separate extras without counting anything twice. Allow for agreed increases in price. Earlier usage guides an estimate; it cannot promise what your next bill will be.

Make room for phone costs

Your phone budget needs the upfront cost and agreed monthly payments, including planned price increases. Some payments repay a handset; service-only plans do not. See whether you can afford them while covering your other needs.

Find out whether insurance, repairs or usage beyond your allowance could cost more. Before ending a deal early, read its cancellation terms and check your local rights. You might owe an exit fee. Money saved for surprises can help cover unexpected expenses.
