Calculate your trash bill per billing period, month and year from the base service charge, extra containers, pickups, bags and fees, plus any tax.
Trash Bill Formula
Add the base service charge, container charges, recurring add-ons, extra pickups, extra bags or tags, and one-time fees. All amounts are USD. Blank optional charges and counts mean zero. Apply the entered tax or surcharge rate to the whole subtotal and round tax half up to a cent:
C = (B + Nc * Fc + A + Np * Fp + Nb * Fb + O) * (1 + T)
The annual model includes this full bill once and k−1 recurring-only bills, with tax rounded once per bill:
Y = C + (k - 1) * R
Variables:
- C is the estimated bill for the current billing period
- B is the base service charge
- Nc and Fc are the number of containers and the fee per container
- A is the recurring recycling, yard-waste, or other add-on charge
- Np and Fp are the number and fee for extra pickups
- Nb and Fb are the number and fee for extra bags or tags
- O is other one-time fees and T is the tax or surcharge rate as a decimal
- Y is the annual model cost, C is this full bill, R is a recurring-only bill including cent-rounded tax, and k is the selected bills-per-year model
Maximum-extra-pickups mode finds the greatest whole count whose bill, including cent-rounded tax, stays within the budget. A positive pickup fee is required for a finite maximum. The method accounts for rounding boundaries instead of dividing only a pretax budget.
Trash Billing Frequencies
The selected frequency determines how often recurring service charges are included in the annual estimate.
| Billing schedule | Bills per year | Monthly equivalent of recurring bill |
|---|---|---|
| Monthly | 12 | Bill amount |
| Every 4 weeks | 13 | Bill amount * 13 / 12 |
| Every 2 months | 6 | Bill amount / 2 |
| Quarterly | 4 | Bill amount / 3 |
| Every 6 months | 2 | Bill amount / 6 |
| Annually | 1 | Bill amount / 12 |
The every-four-week model uses13bills per52weeks. Actual calendar-year invoice counts depend on billing dates; use those dates for an exact annual budget. The frequency table applies to recurring charges; extras are counted once in the annual model.
Example Problems
Example 1: Calculate a quarterly trash bill.
The base quarterly charge is $75. Two containers cost $8 each, recycling costs $10, one extra pickup costs $20, and tax is 5 percent. The subtotal is $75 + 2 * $8 + $10 + $20 = $121. The bill is:
C = $121 * 1.05 = $127.05.
The recurring-only quarterly bill is($75 +2 ×$8 +$10) ×1.05 =$106.05. Counting the extra pickup once, the annual model is$127.05 +3 ×$106.05 =$445.20; the monthly average is$37.10.
Example 2: Find extra pickups within a budget.
A monthly bill budget is $100. Known pretax charges total $62, each extra pickup costs $15, and there is no tax. The available amount is $38. Dividing by $15 gives 2.53, so the household can add two whole pickups and remain within budget.
Frequently Asked Questions
What charges can appear on a trash bill?
Common items include a base collection charge, cart or container fees, recycling, yard waste, extra pickups, bulky-item collection, extra bags or tags, disposal fees, fuel or environmental surcharges, and tax.
How do I compare municipal and private trash service?
Convert each option to an annual cost and match the service level. Compare pickup frequency, cart size, recycling and yard-waste inclusion, bulk-item rules, extra-bag pricing, contract term, and any cost already embedded in property taxes or association dues.
Why is every-four-week billing more expensive than monthly billing?
A four-week cycle occurs13times in52weeks. At the same recurring amount per bill, the13-bill model costs one bill more than the12-bill monthly model. Actual invoice dates determine a calendar year’s bill count.
