Scenario ① · No capitalization (simple interest)
Formula: Income = P × r × t
| Income for 18 months | 229.35 BYN |
| Amount receivable at the end of the term | 1,229.35 BYN |
| Total return over the term | +22,935% |
This method is convenient for a head-on assessment, but it underestimates the benefit if the bank actually capitalizes interest more often than once every 18 months.
Scenario ② · Monthly Compounding
Formula: S = P × (1 + r/12)12×t
| Monthly nominal rate (r/12) | ≈ 1.2741667% per month |
| Total amount after 18 months | 1,255.96 BYN |
| Income (interest) | 255.96 BYN |
| Total return over the term | +25,596% |
With capitalization, the result is 26.61 BYN higher than the scheme without capitalization.
Effective Annual Rate (EAR)
With monthly compounding, the effective annual rate is calculated as: EAR = (1 + r/12)12 − 1
| EAR (effective annual) | ≈ 16.408% |
| Interpretation | This is the "real" annual yield, taking into account interest on interest, compounded monthly. |
Key findings
- Without capitalization: you will receive approximately 1,229.35 BYN (income 229.35 BYN).
- With monthly capitalization: receive approximately 1,255.96 BYN (income 255.96 BYN).
- The difference between the scenarios is about 26 BYN in favor of capitalization over 18 months.
- The effective annual return with monthly capitalization is approximately 16.41% per annum .
What can change the outcome?
- Payment schedule: If interest is paid monthly to the card (without adding to the deposit), the result will be closer to the scenario without capitalization.
- Taxes/Fees: Possible income taxes on interest income and bank fees reduce net returns.
- Early termination: usually results in a reduced rate or loss of interest.
- Bank rounding: Monthly rounding may slightly change the final penny amount.
The calculations provided demonstrate the principles and precise figures for a 15.29% annual interest rate and 18-month term. For the final assessment, use your bank's actual terms and conditions: capitalization frequency, tax regime, fees, andrules for early termination.
