About Our Finance Calculators
Financial literacy begins with accurate numbers. Calculent's finance calculator suite covers every aspect of personal finance for Indian users — from calculating your home loan EMI before approaching a bank, to projecting your SIP corpus for retirement planning, to computing your exact income tax liability for both old and new tax regimes.
All calculators use verified formulas sourced from RBI, SEBI, CBDT, and AMFI. Every formula is reviewed quarterly and updated within 24-48 hours when regulatory changes occur (Union Budget, RBI rate changes, GST Council notifications). Results run entirely in your browser — no data is ever transmitted to any server.

The 50-30-20 Rule for Indian Incomes
For a take-home salary of ₹80,000/month: 50% (₹40,000) for necessities (rent, EMI, utilities, groceries), 30% (₹24,000) for wants (dining, entertainment, subscriptions), 20% (₹16,000) for savings and investments (SIP, PPF, emergency fund). Use the Salary Calculator to first compute your true take-home, then allocate accordingly.
The Right Order of Investments
- Emergency Fund First: 3-6 months expenses in liquid FD or savings account
- Tax-Saving Investments: Max out Section 80C (₹1.5L) via EPF + PPF + ELSS
- Health Insurance: ₹5-10L cover (₹25K premium = ₹25K 80D deduction)
- High-Interest Debt: Pay off personal loans and credit card debt aggressively
- Long-Term Equity SIP: 60-70% of investable surplus in diversified equity SIPs
- Goal-Based Investing: Separate SIPs for each goal (education, home, retirement)
EMI-to-Income Benchmark
Total EMI obligations should not exceed 40% of gross monthly income. At ₹1L gross income: maximum total EMI = ₹40,000. Reserve at least ₹10,000 buffer for lifestyle expenses. If existing EMIs are high, reduce new loan principal or extend tenure — but track total interest impact using the EMI Calculator.
Frequently Asked Questions
The SIP Calculator and FD Calculator are the most widely used. SIP suits equity mutual fund planning (12-15% expected returns), while FD suits conservative investors (6.5-9.5% guaranteed). Use the SIP vs FD Calculator to directly compare both for your specific tenure and amount.
Use the EMI Calculator with: loan amount (post down payment), interest rate (8-9.5% in 2026 for home loans), and tenure (up to 30 years). The formula: EMI = P × r × (1+r)⿠/ ((1+r)⿠- 1). For ₹50L at 8.5% for 20 years, EMI ≈ ₹43,391/month with total interest ≈ ₹54.1L.
Compare both regimes using the Income Tax Calculator. Old regime wins if deductions (80C + HRA + home loan interest + 80D) exceed ₹3.5-4L. New regime wins for most taxpayers with deductions below ₹3L. The break-even point for most salaried employees is around ₹3.25L in total deductions.
₹1 crore at 6% inflation for 20 years is equivalent to only ₹30-35L in today's value. For a comfortable retirement (₹50,000/month today, 30-year retirement), you need ₹5-7 crore corpus by retirement. Use the SIP Calculator to work backward from your retirement goal to find the required monthly SIP.
PPF: guaranteed 7.1%, EEE tax status, 15-year lock-in, zero risk. ELSS: historical 12-15% returns, 3-year lock-in (shortest among 80C options), LTCG taxable above ₹1L. Recommended split: 50% in ELSS (for growth), 30% in PPF (for safety), 20% in EPF (mandatory). Use PPF and SIP calculators side-by-side to compare.
