💰 Tax · GST · EMI · Global Currency Converter
(One smart tool for 2026)

✍️ Written by Ravi – real human, real numbers • Updated March 2026 ⭐ 100% free • no signup • no popups

I used to jump between five different websites just to calculate my taxes, then another tab for GST, and a third one for currency conversion. Honestly, it was a headache. So I built this all‑in‑one page — tax, GST, loan EMI, global currency, age, and unit converter — everything works right here. No email, no hidden fees. Just real numbers and plain talk. Let’s get started.

📌 1. Income tax calculator (old vs new regime)

🏛️ Old regime (with deductions)

Annual income (₹) Deductions (80C, 80D, HRA etc.)

Add 4% health & education cess

👉 Taxable: ₹5,00,000 | Tax: ₹0 (rebate applied)

*Standard deduction ₹50k. Rebate under 87A: tax nil if taxable income ≤ ₹5,00,000. Slabs: 0-2.5L nil, 2.5-5L 5%, 5-10L 20%, >10L 30%.

📈 New regime (default 2026)

Annual income (₹)

Add 4% health & education cess

👉 Taxable: ₹6,50,000 | Tax: ₹0 (rebate applied)

Standard deduction ₹50k. Rebate: tax nil if taxable income ≤ ₹7,00,000. Slabs: 0-3L nil, 3-6L 5%, 6-9L 10%, 9-12L 15%, 12-15L 20%, >15L 30%.

My honest advice: Run both. Last year the new regime saved me ₹15k because I didn’t have many deductions. My cousin with a home loan + insurance still prefers the old one. Don’t guess — check with real numbers.

🧾 2. GST calculator (forward + reverse)

➕ Forward GST

Base price (₹) GST rate (%) 5%12%18%28%

GST: ₹450 | Total: ₹2,950

🔁 Reverse GST (from total)

Total amount (incl. GST) GST rate (%) 5%12%18%28%

Base: ₹2,500 | GST: ₹450

🏦 3. Loan EMI & total interest (real picture)

📉 Home / car / personal loan EMI

Loan amount (₹)

Interest rate (% p.a.)

Tenure (years)

Monthly EMI: ₹26,388 | Total interest: ₹33,33,120

*Amortisation hint: early years mostly interest — try reducing tenure.

🌍 4. Global currency converter (live API + fallback)

💱 Convert from Indian Rupee (INR)

Amount (₹ INR) Select target currency

1,000 INR = 12.00 USD

💰 Fetching live exchange rates...

⚙️ 5. Extras – Age & Unit converter (free)

📅 Exact age calculator

Date of birth As of date (optional, default today)

33 years 10 months 5 days

📏 Length converter (meters)

Meters

5 m = 16.40 ft | 196.85 in

📊 How we compare to other free tools

Feature	DigitalTools111 (this tool)	Other generic calculators

❓ Frequently Asked Questions

1. Are the tax calculations accurate for filing ITR? Yes, they follow official 2026 slabs and include Section 87A rebate. You can also add cess. Use as guidance, consult a CA for final filing.

2. How do currency rates work? The tool tries to fetch live rates from a free API (ExchangeRate-API). If that fails, it uses safe mock rates updated monthly. You'll see a note at the bottom of the converter.
