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

Having a property for rent 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 deposit does not appear, an immediate question arises: How much can I legally charge in default interest without incurring usury or risking a future legal claim?

Watch out for 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 bases of Law 820 of 2003, the Civil Code, the Commercial Code, and the official certifications of the Financial Superintendency to settle default interest with total 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 set a specific percentage rate for default.

Since there is no fixed rate within Law 820, the housing regime refers to the supplementary rules 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 term expires, without the need for the landlord to make prior judicial requests or demonstrate additional damages.

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

To calculate the daily value of the default, the landlord must thoroughly review what is stipulated in the contractual document signed with the tenant. There are two well-defined legal scenarios:

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 payment of rent, the owner cannot invent a commercial rate. In this scenario, the civil legal interest of 6% annuallygoverns in a supplementary and mandatory manner, as 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

If the parties stipulated by mutual agreement an express default rate in the document, said clause has full validity between the parties, provided it does not exceed the maximum legal usury limit certified by the State. If a contractual clause stipulated an interest rate that exceeds that ceiling, it is considered ineffective by law regarding the excess and entails serious legal consequences.

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

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

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

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

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 settlements, 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 that ceiling is certified is in the guide to usury rate in Colombia.

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

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

According to the active listings on Colombia Move (September 2026), there are 9 active listings for offices and 5 commercial premises. In commercial leases, Article 884 of the Commercial Code provides for 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 result of losing it, they must return the interest already collected, with no extra amount.

Step by step to calculate default interest with practical examples

To calculate late-payment interest in full compliance with the law, a straight-line formula must be used based on the actual calendar days that have passed since the due date. Accrual of interest on interest is strictly prohibited (charging interest on overdue interest), in accordance with Articles 1617 (paragraph 3) and 2235 of the Civil Code.

The simple interest calculation formula is as follows:

Default interest = rent (monthly) value × daily rate × number of days in arrears.

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 (Civil rate of 6% per year)

Let’s 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 default.

• Legal civil annual rate: 6% (0.06 per year).
• Legal daily rate: 0.06 / 365 = 0.00016438 (about 0.0164% per day).
• Calculation: 1,500,000 × 0,00016438 × 15 = 3,699 COP.

In this case, the landlord can only demand payment of $3,699 COP for default interest under the supplemental legal rate.

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

Let’s assume the same rent of $1,500,000 COP and 15 days of arrears, but the contract states that the default interest will be charged at the maximum legal rate permitted by Superfinanciera (Resolution 1260 of 2026: 29.24% E.A., corresponding to an approximate monthly rate of 2.15% for a simple calculation).

• Monthly rate applied: 2.15% (0.0215 per month).
• Daily rate: 0.0215 / 30 = 0.0007166 (about 0.0717% per day).
• Calculation: 1,500,000 × 0,0007166 × 15 = 16,124 COP.

The default-interest amount in this scenario comes to $16,124 COP. As you can see, even under the maximum usury rate, default interest for just a few days of delay does not amount to disproportionate sums—contradicting the incorrect practice of some owners who demand arbitrary fixed penalties of $50,000 or $100,000 COP without support in the contract.

Formal collection procedure and when to seek legal action

To avoid damaging the relationship with the tenant and to keep an appropriate evidentiary record, it’s essential to proceed with method and formality:

1. Issue a detailed payment/demand statement: When submitting the receipt or demand statement, break down the unpaid rent value separately from the value corresponding to the calculated days of default.
2. Differentiate default from the 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 remains in force and unilateral formal termination has not been formally notified.
3. Notify via the contractual channel: If the tenant is more than 30 days in default or accumulates several unpaid months, send a formal communication via certified mail to the physical or electronic address registered in the contract.
4. Initiate restitution of the property: In the event of systematic and unjustified breach, the landlord is authorized to terminate the contract under Article 22 of Law 820 and to call an extrajudicial conciliation hearing, or file an lawsuit for the restitution of a rented property.

Frequently asked questions

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

The maximum is the usury rate set by Superfinanciera, and only if the contract agreed to 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, don’t use that cap: apply the 6% per year under Article 1617 of the Civil Code. This rule remained in force through September 2026.

❓ If the rental contract says nothing about default interest, can I charge it?

Yes, but only at 6% per year under Article 1617 of the Civil Code. This legal civil interest is equivalent to 0.5% nominal per month and applies when the contract for an urban housing unit is silent. Law 820 of 2003 does not set its own percentage and refers to that supplemental provision. This rule remained in force through September 2026.

❓ From which day do I start counting default interest on the rent?

Interest accrues from the day after the payment date agreed in the contract. No prior letter or judicial notice is required: paragraph 2 of Article 1617 of the Civil Code states that mere delay is enough. Count only the calendar days of arrears on the unpaid rent. This rule remained in force through September 2026.

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

Yes, it’s feasible if the contract states that the penalty does not extinguish the main obligation. Don’t charge the penalty clause for a short delay while the contract remains in effect and there was no formal termination. Default compensates for the delay; the penalty punishes the definitive breach. This distinction remained in force through September 2026.

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

No—charging interest on overdue interest is interest on interest (anatocism) and is prohibited. Articles 1617 (paragraph 3) and 2235 of the Civil Code require calculating default interest only on the principal amount of the overdue rent (straight-line and by days). Doing it on balances that already include prior default interest is illegal. This prohibition remained in force through September 2026.

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

You can list your home, office, or commercial space on Colombia Move with no real estate brokerage commission. The listing includes direct contact, and you set the contract, the payment date, and the default clause before handing over the keys. According to active listings from September 2026, there are 9 offices and 5 commercial premises. This option remained in force through September 2026.
