The Complete Guide to Splitting Rent & Utility Bills in Shared Apartments in Saudi Arabia 2026

Living costs in Riyadh, Jeddah, and Dammam are high. Sharing an apartment is the best financial decision, but splitting bills fairly can be a headache. This guide shows you exactly how.

Introduction

If you live in Saudi Arabia, you already know the reality: rents in Riyadh, Jeddah, and Dammam have been climbing steadily. A decent 2-bedroom apartment in a good neighborhood can cost 40,000 to 60,000 SAR per year. Add to that the SEC electricity bill which, in summer, can exceed 1,000 SAR per month for a single apartment, plus water, internet, and other utilities. The numbers add up fast.

Sharing an apartment is the smartest way to cut your housing costs by 40–50%. But here is the problem everyone faces: how do you split the bills fairly? Does the person with the master bedroom pay more? What if one roommate runs the AC at 18°C while you prefer 24°C? And how do you handle late payments without awkward conversations?

This guide answers all these questions. You will learn the fairest methods for splitting rent and utilities, see real calculation examples, and get practical tips for avoiding roommate conflicts over money. Plus, use our free Bill Splitter Calculator to get an exact breakdown in seconds.

What Expenses Need to Be Split?

Before moving in together, agree on exactly which expenses will be shared. Here is the standard list for Saudi apartments:

1. Monthly Rent

The biggest expense. Usually paid by post-dated cheques or SADAD auto-payment. Split method should be agreed before signing the contract.

2. SEC Electricity Bill

The most variable expense. Can range from 200 SAR in winter to 1,500+ SAR in peak summer. AC usage is the main driver. Track it via the SEC smart meter app for transparency.

3. Water Bill

National Water Company bill. Usually a small fixed amount (30–80 SAR/month) but can spike if you have a garden or use a lot of water.

4. Internet/Wi-Fi

STC, Mobily, or Zain fiber packages. Fixed monthly cost, easily split equally. Choose a plan that matches your speed needs.

5. Gas Cylinders

If you use gas for cooking. A large cylinder costs about 30–40 SAR and lasts 1–3 months depending on usage.

6. Cleaning/Maid Service

If you share a maid service, split the cost equally. Decide on frequency (weekly, bi-weekly) beforehand.

Fair Splitting Methods

Method 1: Equal Split

Best for apartments where all rooms are similar in size and everyone uses common areas equally. Simply divide total expenses by the number of roommates. This is the simplest and most common method.

Method 2: Proportional Split by Room Size

Use this when one person has a master bedroom with an attached bathroom. The master bedroom occupant pays a premium (typically 10–20% more). Common splits: 60/40 for 2 roommates, or 40/30/30 for 3 roommates where one has the master.

Method 3: Usage-Based Split

Best for variable expenses like electricity. If one roommate works from home and runs AC all day, while others commute and use AC only at night, adjust the electricity share accordingly. Use the SEC smart meter app to track consumption patterns transparently.

⚠️ Pro Tip

Combine methods for best results: split rent proportionally by room size, and split utilities equally or by usage. Our Bill Splitter Calculator supports all these methods.

Step-by-Step Calculation Formula

Step 1: Add all fixed costs (Rent + Internet + Maid service)

Step 2: Add all variable costs (SEC bill + Water + Gas)

Step 3: Total shared expenses = Fixed costs + Variable costs

Step 4: Divide by number of roommates (for equal split)

OR

Step 4: Apply proportional percentages (for master bedroom premium)

Step 5: Each person's total = rent share + utility share

Real-Life Calculation Examples

Example 1: Equal Split — Two Roommates in a 2BHK

Total expenses: 3,000 SAR rent + 400 SAR SEC + 100 SAR water + 200 SAR internet = 3,700 SAR

Per person: 3,700 ÷ 2 = 1,850 SAR/month

Example 2: Proportional Split — Three Roommates with Master Bedroom

Total expenses: 4,500 SAR rent + 600 SAR SEC + 100 SAR water + 250 SAR internet = 5,450 SAR

Split ratio: Master bedroom pays 40%, other two pay 30% each

Master bedroom: 5,450 × 0.40 = 2,180 SAR/month

Each other roommate: 5,450 × 0.30 = 1,635 SAR/month

Example 3: Usage-Based Adjustment for AC

SEC bill: 800 SAR. Roommate A works from home (60% usage), Roommate B works at office (40% usage).

Roommate A pays: 800 × 0.60 = 480 SAR

Roommate B pays: 800 × 0.40 = 320 SAR

Top Tips to Avoid Roommate Conflicts Over Money

1. Set a Monthly "Bill Payment Day"

Pick a specific date every month (e.g., the 5th) for everyone to transfer their share. This creates a routine and eliminates last-minute scrambling.

2. Use Tracking Apps

Use our Bill Splitter Calculator for the initial breakdown, then track ongoing expenses with apps like Splitwise. This keeps everyone accountable and avoids memory disputes.

3. Agree on AC Rules Before Summer

Summer electricity bills are the #1 cause of roommate arguments. Agree on a temperature range (23°C–25°C), operating hours, and whether personal AC units in rooms are tracked separately.

4. Keep a Security Deposit

Collect one month's rent as a deposit before moving in. This covers any unpaid bills if someone leaves suddenly or can't pay.

5. Communicate Openly

If someone is struggling to pay, talk about it early rather than letting it fester. Consider setting up a joint bank account or shared SADAD auto-debit so bills are always paid on time.

How to Pay Shared Bills in Saudi Arabia

SADAD Payment System

One person pays the full bill through SADAD using their bank app (Al Rajhi, SNB, Riyad Bank, Alinma). The others transfer their share immediately via Urpay (from Al Rajhi), STC Pay, or direct bank transfer.

Auto-Pay via Bank App

Set up auto-debit for SEC and other bills. One person pays, and others use Urpay or STC Pay for instant transfers. Most Saudi banks support these instant transfer services free of charge.

Rent Payment

Rent is typically paid via post-dated cheques (each roommate gives their share as a cheque) or through the Ejar platform. Some landlords now accept SADAD payments for monthly rent.
