\u2013 Calculation Example<\/h2><\/div>\r\n\r\n<\/p>\n<p><strong>Example:<\/strong> three housemates share a $2,400 apartment. The bedrooms measure 120, 150 and 180 ft\u00b2, and the shared areas total 300 ft\u00b2. No room carries a premium, so all \\(p_i = 0\\).<\/p>\n<p>\\[ w_1 = 120 + \\tfrac{300}{3} = 220,\\quad w_2 = 150 + 100 = 250,\\quad w_3 = 180 + 100 = 280 \\]<\/p>\n<p>\\[ \\text{Room 1: } 2400\\cdot\\frac{220}{750} = 704.00,\\quad \\text{Room 2: } 2400\\cdot\\frac{250}{750} = 800.00,\\quad \\text{Room 3: } 2400\\cdot\\frac{280}{750} = 896.00 \\]<\/p>\n<p><strong>Result:<\/strong> Room 1 pays <strong>$704.00<\/strong> (29.3%), Room 2 pays <strong>$800.00<\/strong> (33.3%) and Room 3 pays <strong>$896.00<\/strong> (37.3%) per month \u2014 exactly $2,400 in total. The effective rent works out to $3.20 per ft\u00b2 of total area (750 ft\u00b2).<\/p>\n<p>\n\r\n<\/section>\n<h2>How to use the calculator<\/h2>\n<ol>\n<li>Enter the <strong>Total monthly rent<\/strong> for the whole property.<\/li>\n<li>Set the <strong>Number of rooms<\/strong> (2\u20135). Fields for Room 4 and Room 5 appear automatically when needed.<\/li>\n<li>Enter each <strong>Room area<\/strong> in ft\u00b2 or m\u00b2 \u2014 pick the same unit for every field.<\/li>\n<li>Enter the <strong>Shared area<\/strong>: kitchen, living room, bathrooms and any other space all housemates use. Enter 0 if you want to split based on bedroom size only.<\/li>\n<li>Optionally add <strong>Premium per room<\/strong> amounts in the text field, separated by semicolons (e.g. <code>0; 50; 100<\/code>). One amount per room, in room order \u2014 or leave it empty.<\/li>\n<li>Read the results: a table with each room's suggested share (in dollars and percent) and the effective rent per unit of total area.<\/li>\n<\/ol>\n<h2>What is a rent split by room size?<\/h2>\n<p>When a flat or house is shared, splitting the rent exactly equally often feels unfair: the person in the small box room pays the same as the one with a large bedroom and an ensuite. A size-based split answers that by charging each housemate in proportion to the space they occupy. The bigger your private area, the bigger your share of the rent.<\/p>\n<p>The method used here is a little more refined than a simple area ratio. Shared spaces \u2014 kitchen, living room, hallways, bathrooms \u2014 benefit everyone equally, so their cost is spread evenly rather than by room size. Each room's weight is its own area plus an equal slice of the shared space, and the rent is divided in proportion to those weights. If you set the shared area to 0, the calculation reduces to a pure per-square-foot split of the bedrooms.<\/p>\n<p>Premiums handle the features that area alone doesn't capture: an ensuite bathroom, a private balcony, a quiet back-facing room or a great view. Each premium is a fixed dollar amount added straight to that room's share; the rest of the rent is then divided by area, so premiums never distort the proportional part of the calculation. Note that the premiums together must be less than the total rent \u2014 otherwise there would be nothing left to divide.<\/p>\n<p>Interpreting the result is straightforward: the percentages show each room's share of the total rent, and the dollar amounts always add up to the full rent. The second result, effective rent per unit of total area, tells you how much each square foot or square metre of the property costs \u2014 useful for comparing this apartment's value against other listings.<\/p>\n<h2>Assumptions, limitations and practical tips<\/h2>\n<ul>\n<li><strong>One person per room.<\/strong> The calculator assumes each bedroom has a single occupant. If two people share a room, a common approach is to treat them as splitting that room's share between them.<\/li>\n<li><strong>Same unit everywhere.<\/strong> All areas \u2014 rooms and shared space \u2014 must use the same unit (ft\u00b2 or m\u00b2). The unit only affects the \"per unit of area\" result; the dollar shares are identical either way.<\/li>\n<li><strong>Shared space is valued equally.<\/strong> If one housemate works from home and uses the living room far more than others, you can partly account for it by assigning that person a modest premium.<\/li>\n<li><strong>Area isn't everything.<\/strong> Floor level, natural light, noise, closet space and privacy all matter. Use premiums to fine-tune, and treat the suggested numbers as a fair starting point for a conversation, not a verdict.<\/li>\n<li><strong>Re-check after changes.<\/strong> If rent rises or someone swaps rooms, recalculate \u2014 the old split rarely stays fair.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Split rent fairly between housemates based on bedroom size.
