Financial Calculators

Every engineer eventually runs into the reality that the right technical decision also has to hold up financially — it should deliver the required performance while staying efficient to run, controlled on cost, and sound for long-term value. Alongside its engineering tools, ElectroMechCalc also carries a set of financial calculators for everyday planning — SIP, CAGR, and loan/EMI tools that work with any currency, plus India-specific tools for the numbers that come up on every Indian payslip and savings account (EPF, gratuity, PPF, NPS, and fixed or recurring deposits). The goal is the same as on the engineering side: a straight, formula-based answer you can verify, not a sales pitch dressed up as a calculator.

Use SIP & Lump Sum or CAGR to check how an investment is likely to grow, EPF, PPF, or NPS to plan for retirement, FD or RD to compare bank deposit maturity values, or the Income Tax Calculator to see whether the old or new regime works out cheaper for you this year.

What's Covered

Retirement & long-term savings: EPF, PPF, and NPS calculators project your corpus at retirement using the same interest-crediting and compounding conventions EPFO, the government, and PFRDA actually use — not a simplified approximation.

Bank deposits: FD and RD calculators handle quarterly-compounding maturity value, so you can compare a lump-sum deposit against a monthly recurring one on equal terms.

Market-linked growth: SIP & Lump Sum and CAGR calculators show both the nominal and annualized (CAGR) growth rate of an investment, with a year-wise breakdown so the compounding effect is visible, not just the final number.

Tax & inflation planning: the Income Tax Calculator compares Old vs New regime side by side using your actual deductions, while the Inflation Calculator and Gratuity Calculator round out the picture for salary and retirement planning.

Who These Calculators Are For

Salaried employees checking their EPF/gratuity numbers against a payslip, first-time investors comparing SIP against a bank FD, and anyone deciding between the Old and New income tax regime before filing — these calculators are built for a quick, trustworthy number you can act on, not a lead-generation form for a financial product.

Built With ElectroMechCalc's Engineering Audience in Mind

India's engineering workforce — plant, site, EPC, and maintenance engineers especially — tends to have a salary structure and career pattern that's different from a typical desk job: heavier CTC-to-in-hand gaps from shift/site allowances, project-based contracts instead of continuous permanent tenure, frequent postings to non-metro industrial towns, and increment cycles that don't always track inflation. Several of these calculators cover that ground directly: EPF + SIP retirement planning for salaried engineers, gratuity rules for site & contract engineers, HRA for engineers on site postings, CTC vs in-hand salary for maintenance engineers, and why engineers need inflation-adjusted salary planning.
