Marks to Percentage Converter

Marks to percentage conversion for tests, exams, and assignments

A marks to percentage converter answers one specific question: “What percentage did I get if I scored X marks out of Y?” This is the most common way students, parents, and teachers compare results across different tests. A raw score like 42/60 is hard to interpret at a glance, but 70% is immediately comparable to other scores, pass requirements, and target goals.

This calculator is built for the typical real-world scenario where you already know two numbers: the marks obtained and the total marks available. You enter both values, click convert, and the calculator returns your percentage score. It also shows the same result as a fraction, so you can keep the original “X out of Y” context. If you are aiming for a specific target, you can optionally enter a target percentage to see how many marks that target requires for the same total.

The primary output is the percentage score. That number tells you how much of the available marks you achieved. For example, 42 out of 60 becomes 70%. The supporting outputs help you make a decision without adding complexity. The fraction confirms the inputs were read correctly. The target calculation answers a practical follow-up: “How many marks would I need to reach 75% on a test out of 60?” This is useful when you are setting goals, checking whether a remark could matter, or estimating how much improvement is needed next time.

Assumptions and how to use this calculator

• This converter is only for a single score expressed as marks obtained out of total marks (it does not average multiple subjects).
• Total marks must be greater than 0. If the total is 0, a percentage is undefined and the result is not meaningful.
• Marks obtained can be 0 or higher. If your score includes bonus marks and exceeds the total, the calculator will show a percentage above 100%.
• Target percentage is optional. If provided, the calculator assumes the same total marks and calculates the required marks for that target.
• Decimal places are optional. If you leave it blank, the calculator uses 2 decimals. Values outside 0 to 4 are automatically clamped to keep results readable.

Common questions

How do I convert marks to percentage?

Divide marks obtained by total marks, then multiply by 100. For example, 42 out of 60 is 42 ÷ 60 × 100 = 70%. This calculator performs that calculation and formats the result cleanly.

What if my marks obtained are higher than the total marks?

This can happen with bonus questions or extra credit. The percentage can exceed 100%. The calculator will still compute the percentage using the same formula, so you can see the true relative score.

What if I only know my percentage and need the marks?

This page is intentionally locked to marks-to-percentage conversion as the primary task. If you need the reverse, use a percentage-to-marks calculator. Here, you can approximate the reverse by entering your target percentage and total marks to see the marks required for that target.

Why does the calculator show decimal places?

Percentages often produce repeating decimals, especially when the total marks are not a multiple of 2, 4, 5, or 10. Decimal places help when you need precision for comparisons or cut-offs. If you only need a quick view, set decimal places to 0 or 1.

How accurate is the target marks result?

The required marks value is a direct percentage of the total: target% × total ÷ 100. In real marking, you cannot score partial marks on some questions, so treat the required mark as a threshold. If your assessment only allows whole marks, round up to the next whole mark to be safe.
