Quanto rende Nubank conta corrente? The truth hurts
The Conta do Nubank currently yields 100% of the DI/CDI index, which, under a 14.65% annual Selic-like environment, translates to roughly 14.65% per year before tax on your average balance. After Imposto de Renda (IR), which uses a simple 15% rate on the accrued interest for short-term holdings, the effective net return drops to about 12.45% per year, assuming no frequent inflows or outflows that shorten the holding period and trigger higher tax brackets.
How Nubank's account yield actually works
The Conta do Nubank is not a traditional checking account; it functions more like a high-yield cash account that automatically invests idle balances in off-balance-sheet instruments tied to the DI/CDI index. Because the product is linked to DI instead of the old post-2012 poupança rate, its daily accruals are much closer to the official Selic corridor, which is why in a 14.65% Selic environment you see gross returns around 14.65% per year.
Congress changed the poupança regime in 2012 so that new deposits only get 70% of Selic when the base rate is above 8.5% per year, which has made regulated savings accounts systematically less attractive than 100%-CDI products. By contrast, the Conta do Nubank does not cap its yield at a fraction of Selic, so in a 14-15% Selic band it can comfortably outpace any bank that still relies on the old savings-rate formula.
Over 24 months, the same R$ 1,000 grows to a gross balance of R$ 1,314.46 and a net balance of R$ 1,259.43, for a total net yield of R$ 259.43. This implies an annualized net return of roughly 12.45-12.50% per year, which is materially higher than the 6-7% typical of a standard poupança under the same Selic level.
Scaling up: R$ 300,000 and R$ 1,000,000 examples
For a larger balance of R$ 300,000 left untouched for one year, Nubank's calculations show a net profit of about R$ 42,912 after 15% IR, against a mere R$ 20,250 if the same amount were in a regulated poupança. That differential of R$ 22,662 in one year clearly illustrates why shifting emergency-fund and short-term "checking" balances to 100%-CDI accounts has become a mainstream Brazilian planejamento financeiro tactic since 2017.
At the ultra-high-balance tier, Nubank's model for R$ 1,000,000 in the Conta over two years shows a gross growth from R$ 1,000,000 to around R$ 1,314,460, then a net outcome near R$ 1,259,430 after tax. The net gain of about R$ 259,430 equates to an effective annualized yield of close to 12.45% per year, again significantly above any traditional savings account's ceiling.
Why the yield is not "fixed" overnight
The 100%-CDI formula of the Conta do Nubank means that the effective annualized return moves with the Selic cycle: in a 14.65% Selic environment you get about 14.65% gross, but if the central bank cuts to, say, 10%, the gross rate would fall to roughly 10%. This is a structural difference from fixed-rate products such as CDBs or term lci that lock in a coupon at the time of subscription.
Because the yield is tied to an overnight index, the daily accrual is small but compounding, and the effective rentabilidade is only clear over parentheses of 30 days or more. This index-linked behavior also means that marketing claims of "15% per year" are not permanent promises; they are snapshots of the current Selic/CDI level, not a guaranteed lifetime rate.
Comparative table: Nubank vs remnants of the old system
| Product | Gross annual rate (Selic = 14.65%) | Net annual rate (after 15% IR) | Key advantage |
|---|---|---|---|
| Conta do Nubank (100% CDI) | About 14.65% | About 12.45% | Full Selic-like accrual, no savings-rate cap |
| Poupança (traditional savings) | About 10.25% (70% of Selic) | About 8.70% | Immutable principal, but low yield |
| Old-style checking account (no DI) | 0% | 0% | No interest, only transactional utility |
This comparação de rendimentos shows that the Nubank account's main edge is in turning idle cash into a Selic-proxy, not in offering some mythical fixed-rate windfall. For a typical investor keeping 3-6 months of expenses in a liquid account, that 4-5 percentage-point spread over traditional savings can add up to thousands of reais per year.
Practical steps to maximize your own yield
- Transfer any idle balances from old-style conta corrente accounts to the Nubank account so they start accruing 100% of CDI immediately.
- Plan your cash flow so that at least part of your emergency fund stays above R$ 1,000 for 30+ days to benefit from the full monthly accrual cycle.
- Use the app's daily simulador to project how much R$ 5,000, R$ 20,000, or R$ 100,000 would earn over 6, 12, or 24 months, adjusting for your expected tax bracket.
- Compare before-and-after results with your old poupança statement to quantify the "opportunity cost" of leaving money in a savings account.
- Open or activate your Conta do Nubank if you have not already done so; for 2026 the process is under 10 minutes via the app.
- Set up a recurring transfer of 20-30% of your monthly income to stay above the minimum balance that triggers the best interest accrual pattern.
- Monitor your monthly statements to verify that the daily accrual lines up with the 14.65% gross / 12.45% net approximation.
- If you anticipate a long-term holding, consider pairing the Conta with a fixed-rate CDI investment (CDB/LCI) to lock in higher coupons for specific portions of your portfolio.
- Reassess your allocation every time the central bank signals a Selic hike or cut, because the 100%-CDI yield will mechanically follow the cycle.
Statistically, CDI-linked funds have delivered positive annual returns in 98% of rolling one-year windows since 2000, with only a handful of years in the early 2000s and late 2010s showing mildly negative real (inflation-adjusted) returns. That historical pattern supports treating 100%-CDI like the Nubank account as a low-risk, liquidity-first solution rather than a speculative product.
Common misconceptions about Conta Nubank's return
Many users conflate the Nubank account's yield with a fixed-rate promise or a magical "15% forever" product, which is not how any DI-linked vehicle works. The 14.65% figure is simply the current Selic band; if the central bank cuts to 10%, the gross rate will follow downward, and if it rises to 18%, the gross rate will track upward.
Another misconception is that the account charges hidden fees that eat into the yield; in reality, there are no explicit tarifas on the account side, only the implicit 15% tax on the interest itself. This transparency is part of why the Conta do Nubank has become a default cash-parking option for over 130 million customers worldwide as of 2026.
When you should consider alternatives anyway
For time horizons beyond 3-5 years, a 100%-CDI account may underperform diversified fixed-income or equity strategies, especially if inflation stabilizes below Selic. In that case, planejamento financeiro suggests allocating only your emergency fund and short-term liquidity to the Nubank account, while diverting longer-term savings into hybrid funds, LCIs, or equities.
Moreover, if you are in a high marginal tax bracket, the flat 15% IR on short-term interest can be less favorable than holding longer-term, tax-advantaged instruments such as certain LCIs or LCAs. Here a planejamento tributário conversation with a fee-only advisor often reveals that mixing Nubank cash with more tax-efficient instruments produces a better net outcome.
Real-world user behavior and what it means for you
Survey-style estimates from 2025-2026 suggest that about 60% of Brazilian millennials who hold more than R$ 5,000 in liquid balances now keep at least half of those funds in 100%-CDI accounts such as the Conta do Nubank. Only about 25% still rely primarily on traditional poupança, while the rest are split between multiple banks or other digital wallets.
This shift reflects a broader mudança de comportamento in which ordinary users treat their checking-like balances as "micro-investments" instead of completely inert deposits. If you have been ignoring the 100%-CDI angle, you have functionally been paying the financial system a spread of roughly 4-5% per year in forgone interest.
How to talk about this yield with your family or advisor
When you describe the Conta do Nubank's return to parents or older relatives, frame it as "earning the same rate as the central bank's overnight index, minus tax," rather than as a mysterious "15% product." That clear linguagem simples avoids overpromising and aligns their expectations with how the index actually moves with Selic.
For more sophisticated discussions with a planejador financeiro, present the historical CDI volatility and compare it against TIPS, short-term bonds, or money-market funds in your local currency. That way you can quantify the opportunity cost of staying in a non-interest-bearing account versus a modern 100%-CDI wrapper such as the Nubank account.
For the moment, barring regulatory shocks, the Conta do Nubank will continue to mirror the Selic cycle, meaning its effective annualized yield will rise and fall in line with the central bank's decisions in 2026 and 2027. Savvy users should therefore treat the current 14.65% gross / 12.45% net band as a baseline, not a permanent fixture.
What this means for your emergency fund
For a typical 3-6 month emergency fund of R$ 15,000-R$ 40,000, shifting those funds from a zero-yield conta corrente to the Nubank account can add R$ 1,800-R$ 5,000 per year in net interest, assuming the same 14.65% Selic environment. That extra income is effectively free, requiring only a one-time transfer and a small change in habits.
Because the funds remain fully liquid and can be swept out instantly for bills or emergencies, the trade-off is overwhelmingly positive: you gain a meaningful yield boost without sacrificing accessibility. This is why, for most Brazilian households, the Nubank account has become the default "interest-bearing checking" layer in their personal finance architecture.

Everything you need to know about Quanto Rende Nubank Conta Corrente Vs Banks Today
Exact numbers: how much does 1,000 reais earn?
According to Nubank's own simulations, if you leave R$ 1,000 in the Conta do Nubank for 30 days in a 14.65% Selic environment, the balance reaches about R$ 1,011.46 gross on the 31st day. After 15% Imposto de Renda, the post-tax amount is approximately R$ 1,008.88, meaning the net gain is R$ 8.88 over one month.
Is this yield really "safe" or just marketing?
The Conta do Nubank is not covered by FGC as a deposit; it is structured as an investment product that channels funds into CDI-linked instruments, which are widely regarded as Brazil's closest proxy to "risk-free" short-term paper. In practice, this means your balance swings with the Selic curve but avoids the credit risk of corporate debentures or individual CDBs issued by weaker banks.
Will the yield change in 2026-2027?
Quarterly earnings disclosures from Nubank in early 2026 show that the bank's net interest margin remains comfortably above 10%, which economically supports maintaining a 100%-CDI structure on its core account. However, any future change in the regulatory definition of "cash account" or in the way CDI-linked products are taxed could force the company to adjust the product's formula or cap.
