❓ Frequently Asked Questions
How to calculate salary hike percentage?▼
Use Track 1 (Hike/Discount): Enter current salary as Original Value and the hike % as Change %. E.g., ₹50,000 with 12% hike = ₹50,000 × 1.12 = ₹56,000.
What is reverse percentage? How to find base price before GST?▼
Reverse percentage (Track 5) finds the whole when you know a part and its percentage. If ₹9,000 is 18% GST, base price = ₹9,000 × 100 ÷ 18 = ₹50,000.
How does sequential compounding differ from simple addition?▼
Sequential (Track 6) applies each % on the running total. ₹10,000 with 10% then 4%: ₹10,000 × 1.10 = ₹11,000, then × 1.04 = ₹11,440. Adding 14% directly gives only ₹11,400 — a ₹40 difference.
How to calculate percentage change (increase or decrease)?▼
Track 4: % Change = ((Final − Initial) ÷ Initial) × 100. A positive result shows an increase (shown in green ↑). A negative result shows a decrease (shown in red ↓).
What is "A is what % of B"?▼
Track 3 (Fraction Converter): Calculates what fraction A is of B, expressed as a percentage. E.g., scored 450 out of 600 marks → (450 ÷ 600) × 100 = 75%.
