Frequently Asked Questions

Find Quick Answers

What's the difference between linear and compound methods?

Linear method assumes simple interest where daily rates are calculated by dividing the monthly rate by 30. Compound method accounts for exponential growth using the formula: daily_rate = (1 + monthly_rate/100)^(1/30) - 1.

Can I use this for negative interest rates?

Yes, the tool supports negative monthly rates (e.g., -0.5%) for scenarios like deflation or penalty rates. Both calculation methods work with negative values.

Why are there 30 days in the calculation?

We use 30 days as a standard month for financial calculations, which is common in banking and finance. You can adjust results manually if your specific case uses a different number of days.
