Default Interest on Rental Payments in Colombia: Legal Calculation and Usury Limits

Leasing a property represents a stable source of income, but dealing with recurring delays in payment dates is one of the most common headaches for any landlord in Colombia. When the fifth or tenth day of the month arrives and the rent payment hasn't appeared, an immediate question arises: How much can I legally charge in late interest without incurring usury or putting a future legal claim at risk?

Watch the price: many owners make the serious mistake of applying arbitrary rates, such as setting an invented 5% or 10% monthly surcharge, or accumulating interest on overdue interest. Within the Colombian legal framework, charging above regulatory limits not only invalidates the charge but can also lead to the civil loss of all returns and even criminal sanctions for the crime of usury. Below, we break down the regulatory foundations of Law 820 of 2003, the Civil Code, the Commercial Code, and the official certifications from the Financial Superintendence to calculate default interest with complete legal certainty.

Can default interest be charged on urban housing leases?

The short answer is yes. However, there is widespread confusion regarding Law 820 of 2003 (Urban Housing Lease Regime). Number 1 of Article 22 covers only the non-payment of rent and adjustments within the term stipulated in the contract. Public utilities are in number 2, and only when such non-payment causes disconnection or loss of service. Common expenses are the other branch of number 2, when their payment is the responsibility of the tenant; they do not depend on a disconnection. In none of its articles does Law 820 fix a specific percentage rate for default.

Since there is no fixed rate within Law 820, the housing regime refers to the supplementary standards of the Colombian Civil Code and general financial regulations. According to number 2 of Article 1617 of the Civil Code, the delay in the fulfillment of a monetary obligation makes default interest demandable as a matter of law from the moment the agreed deadline expires, without the need for the landlord to issue prior legal requests or demonstrate additional damages.

Contract with a default clause vs. Contract in silence: The two legal scenarios

To settle the daily value of the default, the landlord must meticulously check what is stipulated in the contractual document signed with the tenant. Two clearly differentiated legal scenarios arise:

Scenario A: The contract says nothing about default interest

If the lease agreement remained silent and did not include any penalty clause or sanction for late rent payment, the owner cannot invent a commercial rate. In this scenario, the 6% annual legal civil interestapplies in a supplementary and mandatory manner, contemplated in number 1 of Article 1617 of the Civil Code. This percentage is equivalent to exactly 0.5% nominal monthly

(about 0.0164% daily).

Scenario B: The contract agreed on a conventional default rate

Usury limits and current rates from the Superfinanciera (September 2026)

The supreme ceiling for any interest charge in Colombia is delimited by the usury rate, which is legally equivalent to 1.5 times the Current Banking Interest (IBC) certified monthly by the Financial Superintendence of Colombia for consumer and ordinary credit modalities.

For the month of September 2026, the Financial Superintendence issued Resolution 1260 of 2026certifying the following official parameters:

• Current Banking Interest (IBC): 19.49% effective annual.
• Legal Usury Rate: 29.24% effective annual.

No landlord, under any circumstances, can charge an effective default rate higher than 29.24% annually during this period of September 2026. These certifications change every month, so do not use this figure for the rest of the year. Converted to a reference rate for simple liquidations, the monthly limit is approximately 2.15% to 2.16% monthly. Exceeding this figure constitutes the crime of usury sanctioned in Article 305 of the Penal Code and grants the tenant the possibility of requesting the restitution of excess charges. The detail of how this cap is certified is in the guide to usury rate in Colombia.

Differences between urban housing and commercial contracts (offices and shops)

The nature of the property defines the regulatory framework that governs default interest when contractual clauses are not explicit:

According to active ads on Colombia Move (September 2026), there are 9 active ads for offices and 5 commercial premises. In commercial leases, Article 884 of the Commercial Code includes a severe penalty: if the landlord charges interest that exceeds the legal limit, they will lose all interest, without prejudice to Article 72 of Law 45 of 1990. As a consequence of losing them, they must return the interest already collected, without an extra sum.

Step-by-step guide to calculating late payment interest with practical examples

To calculate default interest in full compliance with the law, a linear formula must be applied based on the actual calendar days elapsed since the due date. Anatocism is strictly prohibited (charging interest on overdue interest), in accordance with Articles 1617 (paragraph 3) and 2235 of the Civil Code.

The simple calculation formula is as follows:

Default interest = rent value × daily rate × days late.

Where the daily rate is obtained by dividing the agreed monthly rate by 30 days (or the civil annual rate by 365 days).

Example 1: Housing contract without a stipulated rate (6% annual civil rate)

Imagine an apartment with a monthly rent of $1,500,000 COP, with a payment deadline on the 5th of each month. The tenant makes the payment on the 20th of the month, accumulating 15 net days of arrears.

• Legal annual civil rate: 6% (0.06 annually).
• Legal daily rate: 0.06 / 365 = 0.00016438 (about 0.0164% daily).
• Calculation: 1,500,000 × 0.00016438 × 15 = 3,699 COP.

In this case, the landlord can only demand the collection of $3,699 COP for supplementary legal default interest.

Example 2: Contract with a default clause at the usury limit (September 2026)

Suppose the same rent of $1,500,000 COP and 15 days late, but the contract stipulated that interest would be charged at the maximum legal rate allowed by the Superfinanciera (Resolution 1260 of 2026: 29.24% E.A., corresponding to an approximate monthly rate of 2.15% for a simple calculation).

• Applied monthly rate: 2.15% (0.0215 monthly).
• Daily rate: 0.0215 / 30 = 0.0007166 (about 0.0717% daily).
• Calculation: 1,500,000 × 0.0007166 × 15 = 16,124 COP.

The amount corresponding to default interest in this scenario amounts to $16,124 COP. As observed, even under the maximum usury rate, the default amounts for a few days of delay do not represent disproportionate sums, debunking the erroneous practice of some owners who demand arbitrary fixed fines of $50,000 or $100,000 COP without support in the contract.

Formal collection procedure and when to go to legal channels

To avoid damaging the relationship with the tenant and to maintain a proper evidentiary file, it is essential to proceed with method and formality:

1. Issue a detailed collection statement: When presenting the receipt or invoice, break down the unpaid rent value separately from the value corresponding to the calculated days of arrears.
2. Differentiate default from penalty clause: Default compensates for the delay in payment; the penalty clause punishes serious or definitive breach. You should not demand the penalty clause for a temporary delay of a few days if the contract is still in force and no formal unilateral termination has been notified.
3. Notify through contractual channels: If the tenant is more than 30 days late or accumulates several months of unpaid rent, send a formal communication by certified mail to the physical or electronic address registered in the contract.
4. Initiate property restitution: In the event of a systematic and unjustified breach, the landlord is empowered to terminate the contract under Article 22 of Law 820 and request an extrajudicial conciliation hearing or file a lawsuit for restitution of leased property.

Frequently Asked Questions

❓ What is the maximum I can charge for late rent interest in Colombia?

The maximum is the usury rate from the Superfinanciera, and only if the contract stipulated it. For September 2026, Resolution 1260 sets that ceiling at 29.24% effective annual, which is 1.5 times the current banking interest of 19.49%. If the housing contract says nothing, do not use that ceiling: apply the 6% annual rate from Article 1617 of the Civil Code. That rule remained in effect as of September 2026.

❓ If the lease agreement says nothing about late payment interest, can I charge it?

Yes, but only at 6% annual from Article 1617 of the Civil Code. That legal civil interest is equivalent to 0.5% nominal monthly and applies when the urban housing contract is silent. Law 820 of 2003 does not set its own percentage and refers to that supplementary rule. That rule remained in effect as of September 2026.

❓ From what day do late rent interest charges begin to accrue?

They accrue from the day after the payment date agreed upon in the contract. No prior letter or judicial request is needed: paragraph 2 of Article 1617 of the Civil Code states that the delay is enough. Count only the calendar days of delay on the unpaid rent. That rule remained in effect as of September 2026.

❓ Can I charge the penalty clause and late payment interest at the same time?

It is viable if the contract says that the penalty does not extinguish the main obligation. Do not charge the penalty clause for a short delay while the contract is still in force and there was no formal termination. Default compensates for the delay; the penalty punishes the definitive breach. That distinction remained in effect as of September 2026.

❓ Is it legal to charge interest on rent interest that is already past due?

No, charging interest on past-due interest is anatocism and is prohibited. Articles 1617, paragraph 3, and 2235 of the Civil Code require that default interest be calculated only on the principal of the overdue rent, linearly and by days. Doing so on balances that already include previous default interest is illegal. That prohibition remained in effect as of September 2026.

❓ Where can I post my property for rent to get solvent tenants without paying a commission?

You can post your housing, office, or local space on Colombia Move without a brokerage commission. The listing will have direct contact and you set the contract, payment date, and default clause before handing over the keys. According to active listings in September 2026, there are 9 offices and 5 commercial spaces. That option remained in effect as of September 2026.
