Learn Beatty's short method for calculating interest quickly and accurately.
This guide presents a practical, table-based approach to computing interest on any sum at 4% to 12% per cent using a 360‑day year. It explains how to handle time, days, and cents, and shows how to apply the method with real examples.
The book outlines a step-by-step process: convert time to a common basis, read the correct figure from the table, and multiply by the principal. It also covers how to cut unnecessary digits to get the needed tenths and hundredths. Clear examples illustrate applying the method to different time spans and rates.
- How to convert months and days into a single quotient for the table
- How to find interest on a given principal and time at a chosen rate
- How to handle dollars and cents when reading results from the table
- Practical examples that demonstrate the method in action
Ideal for readers looking for a fast, reliable way to do basic interest calculations.
