Interest earned on $1,000,000 by TPM rate (30 vs 90 days)
Gross simple interest on a $1,000,000 placement, plus the effective annual yield (TEA) if you keep rolling it over. Computed with the same convention this calculator uses: interest = principal × (TPM ÷ 100) × (days ÷ 365).
| Policy rate (TPM) | Interest — 30 days | Effective annual yield (30-day roll) | Interest — 90 days | Effective annual yield (90-day roll) |
|---|---|---|---|---|
| 25% | $20,548 | 28.1% | $61,644 | 27.5% |
| 29% | $23,836 | 33.2% | $71,507 | 32.3% |
| 32% | $26,301 | 37.1% | $78,904 | 36.1% |
| 40% | $32,877 | 48.2% | $98,630 | 46.4% |
| 50% | $41,096 | 63.2% | $123,288 | 60.2% |
| 60% | $49,315 | 79.6% | $147,945 | 75.0% |
| 70% | $57,534 | 97.5% | $172,603 | 90.7% |
Scale linearly for any amount: e.g. $5,000,000 earns 5× the figure shown. The BCRA's reference rate stood near 29% TNA as of mid-2026. Figures are gross — they ignore taxes and bank fees. The effective annual yield (TEA) exceeds the nominal TPM because it assumes you reinvest each maturity; the shorter the term, the larger that gap.
How it works
How it's calculated
The calculator applies simple interest at the BCRA's monetary-policy rate (TPM) over the number of days you hold the placement:
Interest = principal × (TPM ÷ 100) × (days ÷ 365)The TPM is a nominal annual rate, so it is prorated by the day-count fraction (days/365). The annualized yield (TEA) shown reflects what you'd earn if the same daily return compounded for a full year.
Worked example
Place $1,000,000 at a 60% TPM for 30 days:
Simple vs. effective annual yield
A single 30-day placement earns simple interest. The TEA assumes you keep rolling the placement over and reinvesting, so the gap between the headline TPM and the TEA widens as the rate rises and the term shortens.

Important notes
This is a reference estimate, not financial advice. Confirm the current TPM and your product's exact terms with the BCRA and your bank before placing funds.
