Speed Maths Tricks for Banking Exams help candidates perform calculations faster and save valuable time in the Quantitative Aptitude section. These techniques focus on mental calculation, Vedic Maths shortcuts, fraction-to-percentage conversions, multiplication and division tricks, squares and cubes, simplification, and approximation. Since banking exams require candidates to solve Quant questions under strict time limits, reducing calculation time while maintaining accuracy can help improve overall time management. This guide covers practical speed maths tricks for IBPS, SBI, RRB, and other banking exams, along with methods to build faster calculation skills through regular timed practice.
Speed maths tricks for banking exams are shortcut calculation methods that reduce the number of steps required to solve Quantitative Aptitude questions. They are particularly useful in Simplification, Approximation, Number Series, Data Interpretation and arithmetic-based questions.
For example, instead of calculating 48 × 25 through conventional multiplication, you can use:
48 × 25 = 48 × 100 ÷ 4 = 1200
The objective is not simply to memorise formulas. Candidates should understand when a shortcut is useful and practise it until the method becomes automatic.

Banking examinations use sectional or time-bound Quantitative Aptitude tests, depending on the examination. For example, SBI’s official PO information lists 35 Quantitative Aptitude questions in the preliminary examination, while its current Junior Associate information lists 35 Quantitative Aptitude questions in Prelims.
Therefore, spending too much time on basic calculations can reduce the number of questions you can attempt. Speed maths helps you:
The following speed maths topics for bank exams should be included in your preparation because they form the foundation for faster calculations.
| Topic | What to Learn | Where It Helps |
| Tables | Tables up to 20–30 | Multiplication, DI, Arithmetic |
| Squares | Squares up to 30–50 | Simplification, approximation |
| Cubes | Common cubes up to 20–30 | Calculation-based questions |
| Fractions | Fraction-to-percentage values | DI, Percentage |
| Percentages | Common percentage shortcuts | DI, Profit & Loss |
| Multiplication | Base and distributive methods | Simplification, DI |
| Division | ÷5, ÷25, ÷125 shortcuts | Simplification |
| Approximation | Rounding and estimation | Approximation, DI |
| Mental Maths | Quick addition and subtraction | All Quant topics |
These speed maths tricks for banking exams focus on calculations that repeatedly appear in banking Quant sections. Practise each technique with different numbers instead of memorising only the examples.
Tables are the foundation of fast calculation. Start with tables up to 20 and gradually extend them to 25 or 30.
For example:
17 × 8 = 136
24 × 7 = 168
28 × 9 = 252
Quick recall saves time during multiplication, division and DI calculations.
Memorising frequently used fractions can eliminate lengthy calculations.
| Fraction | Percentage |
| 1/2 | 50% |
| 1/3 | 33.33% |
| 1/4 | 25% |
| 1/5 | 20% |
| 1/6 | 16.67% |
| 1/8 | 12.5% |
| 1/10 | 10% |
| 1/12 | 8.33% |
For example, 12.5% of 800 = 800 ÷ 8 = 100.
For a number ending in 5, multiply the number before 5 by its successor and append 25.
75²
7 × 8 = 56
Therefore:
75² = 5625
Similarly:
85² = 8 × 9 | 25 = 7225
This is one of the easiest calculation shortcuts to practise.
For a two-digit number, add the two digits and place the result between them.
43 × 11
4 + 3 = 7
Therefore:
43 × 11 = 473
For 78 × 11:
7 + 8 = 15
After carrying:
78 × 11 = 858
Since:
25 = 100 ÷ 4
you can divide the number by 4 and multiply by 100.
For example:
48 × 25 = 48 ÷ 4 × 100 = 1200
Another example:
64 × 25 = 16 × 100 = 1600
To divide a number by 5, multiply it by 2 and divide by 10.
240 ÷ 5
= 240 × 2 ÷ 10
= 48
This method is particularly useful when the number is even.
Use:
25 = 100 ÷ 4
Therefore:
600 ÷ 25 = 600 × 4 ÷ 100 = 24
Similarly:
800 ÷ 25 = 32
A useful percentage shortcut is:
A% of B = B% of A
For example:
64% of 25
can be changed to:
25% of 64 = 64 ÷ 4 = 16
Therefore:
64% of 25 = 16
This trick is especially useful in DI and percentage-based arithmetic.
When two numbers are close to 100, the base method can make multiplication faster.
For example:
97 × 103
= (100 – 3)(100 + 3)
Using:
(a – b)(a + b) = a² – b²
we get:
= 100² – 3²
= 10000 – 9
= 9991
Approximation can save considerable time when the question asks for an approximate value or when the answer options are sufficiently far apart.
For example:
398 × 51
can be approximated as:
400 × 50 = 20,000
However, approximation should only be used when the question and answer options allow it. Do not sacrifice accuracy simply to save a few seconds.
Percentage calculations appear across Data Interpretation, Profit & Loss, Simple Interest, Compound Interest and other arithmetic topics. Therefore, percentage shortcuts should be a priority in speed maths practice for bank exams.
| Percentage | Fraction |
| 50% | 1/2 |
| 33.33% | 1/3 |
| 25% | 1/4 |
| 20% | 1/5 |
| 12.5% | 1/8 |
| 10% | 1/10 |
| 6.25% | 1/16 |
| 5% | 1/20 |
For example:
37.5% of 800
= 3/8 × 800
= 300
For two successive percentage changes of a% and b%, the net percentage change is:
a + b + (ab/100)
Use the appropriate sign for increase or decrease.
For example, a 20% increase followed by a 10% increase gives:
20 + 10 + (20 × 10)/100
= 32% increase
Speed maths is especially useful for Data Interpretation, where calculations can consume more time than understanding the graph or table.
Before calculating, check whether the question can be solved through:
For example, if a DI question asks you to calculate 12.5% of 640, do not perform a lengthy percentage calculation.
Simply use:
12.5% = 1/8
Therefore:
640 ÷ 8 = 80
This approach can save several seconds across a complete DI set.
Learning shortcuts is only the first step. Regular speed maths practice for bank exams is required to make these methods automatic.
Follow this simple daily routine:
| Practice Time | Activity |
| 5 minutes | Tables, squares and cubes |
| 5 minutes | Fraction-percentage conversions |
| 5 minutes | Multiplication and division |
| 5 minutes | Simplification questions |
| 5 minutes | Timed Quant practice |
Start without a timer while learning a new trick. Once you understand the method, introduce a time limit and gradually increase the difficulty.
Do not try to become fast by rushing through every question. Accuracy should come first, followed by speed.
A useful progression is:
Understand the concept > Learn the shortcut > Practise slowly > Practise with a timer > Apply in mocks
This prevents candidates from developing fast but inaccurate calculation habits.
Even the best fast maths tricks for banking can reduce your score if used incorrectly. Avoid these common mistakes:
A shortcut should reduce calculation steps, not increase the possibility of an error.
