Rent affordability is often reduced to a single percentage, but the actual cost of housing begins well before a tenant signs a rental agreement and continues beyond the monthly payment. A flat that appears manageable on a property listing can become financially stressful once maintenance, utilities, commuting, deposits, brokerage and moving expenses are included.
The commonly used rule of keeping rent within 30% to 40% of monthly income remains a useful starting point. For a person earning Rs 50,000 a month, that range translates into approximately Rs 15,000 to Rs 20,000. For a monthly income of Rs 75,000, it becomes Rs 22,500 to Rs 30,000. At an income of Rs 1 lakh, the broad range is Rs 30,000 to Rs 40,000.
But the percentage is not a housing policy or a guarantee of comfort. It is only a first filter. The more important question for renters is whether the home can be sustained after all housing-related costs and savings commitments have been accounted for.
The headline rent is an incomplete measure
The main weakness in the way rental affordability is usually assessed is that property listings foreground the rent while pushing other expenses into separate conversations. A tenant may compare two homes based on a monthly figure without calculating how each location affects maintenance, electricity, internet and daily travel.
A simple example illustrates the problem. A tenant earning Rs 60,000 a month may find a flat priced at Rs 20,000. That rent equals about one-third of monthly income and may appear reasonable. If maintenance adds Rs 3,000, electricity and internet cost another Rs 2,500, and the location creates an additional commuting expense of Rs 4,000, the monthly housing burden rises above Rs 29,000. That is close to half the salary.
Sarika Shetty, CEO and co-founder of RentenPe, told NDTV that renters frequently select properties using the headline rent without testing the full cost against their income. She said rent should generally not exceed 30% to 40% of monthly income, adding that moving beyond that range can strain cash flow and reduce savings.
Her point is significant because the cost of a home is not limited to the four walls being rented. A building’s maintenance charges, utility deposits, brokerage, relocation costs and travel distance can change the financial value of a property. In urban housing markets, location is therefore not just a lifestyle choice. It is also a recurring expense.
Savings should come before the rent ceiling
A more reliable way to calculate rent is to begin with the amount a tenant needs to save, rather than the maximum rent that appears affordable. If monthly take-home income is Rs 70,000 and the savings target is Rs 20,000, only Rs 50,000 remains for rent and all other expenses. If regular non-housing expenses consume Rs 25,000, a rent of Rs 25,000 would leave little room for emergencies or unexpected costs.
This calculation also explains why the 30% to 40% rule cannot be applied uniformly. A tenant with high loan repayments, family responsibilities or irregular income may find even 30% difficult to sustain. Another tenant with low debt and stronger savings may be able to manage a similar rent more comfortably.
The difference lies in the structure of household finances. A rent ratio does not show whether income is stable, whether a medical or employment emergency can be absorbed, or whether the tenant is already paying instalments and supporting dependants. The same property can therefore be affordable for one household and financially risky for another.
This is where rental affordability overlaps with household resilience. A flat that consumes nearly all disposable income may still be technically payable every month, but it leaves the tenant exposed to disruption. The source material does not establish a separate affordability standard for different cities or income groups, but it makes clear that the percentage should be treated as a guide rather than a target.
The urban trade-off between space and access
Renters also make a second calculation: how much space they need and where that space should be located. A single person may not require a large two-bedroom home, particularly if an adequately maintained 1RK or compact one-bedroom flat meets their needs. Choosing a smaller home can release money for an emergency fund, investments or other financial priorities.
However, reducing rent does not automatically mean choosing the cheapest property. A lower-priced home may have poor maintenance, limited natural light, inadequate ventilation, dampness or seepage. The neighbourhood may also offer less greenery or weaker access to everyday needs. These factors affect the quality and practical usefulness of the home even when they do not appear in the rent figure.
This creates a familiar urban trade-off. A tenant may pay more for a smaller home in a better-connected location or less for a larger home farther from work. The cheaper option may cease to be cheaper if it adds significantly to daily travel. The source gives the example of a flat that is Rs 4,000 cheaper but adds Rs 5,000 to monthly commuting costs. In that case, the apparent saving becomes a net loss.
The calculation is especially important because commuting is a recurring cost. A one-time decision about location can therefore shape the monthly budget for as long as the tenant remains in the property. The financial comparison between homes should include both the rental payment and the cost of reaching work and other regular destinations.
A fuller housing-cost formula
The practical formula suggested in the source is straightforward: total housing cost equals rent plus maintenance, utilities and additional commuting costs. One-time expenses must then be calculated separately. These include the security deposit, brokerage and moving expenses.
Security deposits can create a particularly heavy upfront burden. If monthly rent is Rs 20,000 and the landlord asks for three months’ rent as a deposit, Rs 60,000 is locked in immediately. Brokerage and moving costs can increase the cash required before the tenant has even occupied the property.
The financial impact of the deposit does not end with the size of the payment. Tenants also need to understand the conditions governing deductions and refunds. Keeping records of payments and ensuring that important terms are written into the agreement can help create a clearer record when the tenancy ends.
This is an institutional gap in the way rental housing is commonly understood. The monthly rent is visible and regularly discussed, while the rules governing deposits, maintenance and renewals may remain unclear. Yet these terms can determine the final cost of the tenancy as much as the advertised rent does.
Negotiation can change the total cost
The quoted rent is not necessarily the final financial arrangement. Depending on the property and market conditions, tenants may be able to negotiate the monthly amount, particularly when they are willing to commit for longer or make a larger upfront commitment. A reduction of Rs 1,500 a month would save Rs 18,000 over a year.
Negotiation, however, should not focus only on the rent. Maintenance, parking, renewal terms, notice periods, deposit conditions and other charges can materially affect the overall cost. A property with a slightly higher rent but fewer additional charges may be cheaper over the full period of occupancy.
The implication is that a rental agreement should be assessed as a package of financial terms rather than a single number. This approach also makes comparisons between properties more meaningful. Two homes with different rents may have similar total costs once their other charges are included.
Rental records and the formalisation question
The source also points to a wider financial dimension of renting. Rent is usually treated as a monthly outflow, but organised records of payments and agreements can have value beyond the immediate tenancy. Shetty said that, where payments are properly documented and reported through eligible channels, they can potentially contribute to a tenant’s credit history.
That possibility does not turn every rental payment into a guaranteed credit benefit. It does, however, underline the importance of maintaining records. Agreements, receipts and payment details may also assist with future disputes, loan applications or applications for another rental property.
The issue reflects the relatively informal nature of many rental transactions. When terms are not clearly recorded, tenants may struggle to establish what was paid, which deductions were permitted or when a deposit was due to be returned. Documentation cannot remove every dispute, but it can make the financial relationship more transparent.
The larger urban question is whether renters are evaluating housing as a complete service or merely purchasing access to a room or flat. The cost of that service includes location, connectivity, building condition, utilities, financial security and the ability to continue saving. A rent percentage captures only one part of this relationship.
A sound rental decision therefore requires five calculations: take-home income, a comfortable rent ceiling, total monthly housing cost, upfront cash requirements and the money left after regular expenses. The evidence supplied supports 30% as a practical target and 40% as a broad upper limit, but it does not establish either figure as universally suitable.
The central lesson is that the right home is not necessarily the largest one a tenant can technically pay for. It is the home whose full cost leaves enough room for savings, emergencies and a stable daily life. For urban renters, that means assessing housing not as an isolated monthly bill, but as part of the wider cost of accessing and living in the city.
