Model Lump Sum, SIP, FD, RD, PPF, retirement & goal plans with any compounding, inflation & tax adjustment, CAGR, charts and CSV/Excel/PDF export — 100% in your browser.
Compare two scenarios side by side — SIP vs lump sum, two rates, monthly vs quarterly, or different compounding.
Work backwards from a target amount — solve for the piece you don't know.
Given a lump-sum target, find the required principal, rate or time (no recurring contribution).
See what a sum will really be worth after inflation, and the real (inflation-adjusted) return.
The Professional Financial Investment Calculator takes the humble compound-interest formula and turns it into a complete planning workspace. Instead of forcing you to guess which single-purpose calculator to open, it models any money-growth scenario — a one-time lump sum, a monthly SIP, a fixed or recurring deposit, a PPF or NPS account, a mutual fund, or a long-term retirement or education goal — with realistic controls for compounding frequency, inflation and tax. Every number is computed instantly in your browser, with charts, a year-by-year growth table and one-click export, so investors, students, professionals, financial advisors and businesses can plan and compare with confidence.
Compound growth of a lump sum is:
where P is the principal, r the annual rate (as a decimal), n the number of compounding periods per year and t the number of years. A regular contribution (annuity) adds:
where i is the periodic rate and m the number of contributions. Derived metrics: CAGR = (Final ÷ Invested)^(1/t) − 1, Effective Annual Return = (1 + r/n)^n − 1, and Inflation-adjusted value = Final ÷ (1 + inflation)^t.
Because compounding is exponential, the back half of any long investment does most of the work. In a 20-year SIP, the final five years typically add more wealth than the first fifteen combined — which is exactly why the year-wise chart and table in this tool are so useful: they make the acceleration visible instead of hiding it behind a single end figure.
The Professional Financial Investment Calculator is a free, browser-based planning tool that grew out of a simple compound-interest calculator into a complete engine for modelling how money grows. Its purpose is to answer, quickly and honestly, the questions people actually ask about their savings and investments: how much will this become, how much do I need to invest to reach a goal, what will it really be worth after inflation and tax, and how does one option compare with another? It does all of this locally, in your browser, so you can experiment freely with real numbers without ever sending them anywhere.
At its core is a single, careful simulation engine. Rather than relying on one closed-form formula that only fits a lump sum, it steps through the investment month by month, applying growth at whatever compounding frequency you choose — daily, weekly, monthly, quarterly, half-yearly, annually or even continuously — and adding your recurring contributions or subtracting your withdrawals exactly when they occur. This period-by-period approach is what lets one tool faithfully represent very different products. A fixed deposit is just a lump sum with no contributions; a recurring deposit or SIP is a stream of equal contributions; an SWP is a stream of withdrawals from an invested corpus; a PPF or NPS account is a yearly or monthly contribution compounded annually. By selecting an investment type at the top, the relevant inputs are pre-filled with sensible defaults, but every field stays editable so you are never boxed in.
The results are deliberately richer than a single final figure. Alongside the headline total investment, interest or wealth gain and final value, the tool shows your ROI, your CAGR (the smoothed annual growth rate of your money), the effective annual return (what your nominal rate actually earns once compounding is applied), and — crucially — the inflation-adjusted value and post-tax value. Nominal returns can be misleading: a corpus that looks impressive in future rupees may buy far less than you expect once inflation is accounted for, and gains are often taxable. By surfacing the real, spendable outcome next to the headline number, the calculator helps you make decisions on the figures that actually matter.
Understanding is easier when you can see it, so the engine feeds four chart views — an area chart, a line chart, a bar chart and a pie split of principal versus interest — all drawn directly on an HTML5 canvas with no external chart library, which keeps the page fast and fully offline-capable. Beneath the charts sits a year-by-year growth table listing, for each year, the amount invested so far, the interest accumulated, the running balance and the year-on-year growth percentage. That schedule can be exported as a CSV for a spreadsheet, an Excel file, a PDF snapshot, or saved as a PNG image of the chart, and the whole view can be sent to your printer. For advisors preparing client illustrations, or students documenting a project, this export path turns an on-screen estimate into a shareable artefact in a couple of clicks.
Beyond the main calculator, four focused modes handle the questions that pure forward projection cannot. Compare places two scenarios on the same axes so you can settle debates like SIP versus lump sum, twelve percent versus fourteen, or monthly versus quarterly compounding, with the difference shown in money rather than hand-waving. The Goal planner works backwards from a target: tell it you want one crore in fifteen years and it solves for the monthly investment, the time, or the rate you would need, using a numerical search over the same simulation engine so the answer is internally consistent. The Reverse calculator does the same for a lump sum, finding the principal, rate or time required to reach a future value. And the Inflation mode isolates the erosion of purchasing power, showing present value, future value, the real return and the rupee "inflation loss" over your horizon. Together these cover the full arc of everyday financial planning without ever needing a spreadsheet.
The tool also respects that money is personal. Everything runs client-side, so your amounts, rates and goals never leave your device; there is no account, no tracking of your figures and no server round-trip. It supports seven currencies with correct local formatting, remembers your recent and saved calculations in your own browser for quick recall, and validates inputs to catch empty, negative or out-of-range values before they produce nonsense. It is designed to be lightweight and responsive, working just as well on a phone during a bank visit as on a desktop, and to remain accessible with clear labels and keyboard-friendly controls. One important caveat applies to every projection here: it assumes a constant rate of return, which real markets and even fixed deposits do not guarantee over long periods. Treat the outputs as informed estimates for planning and comparison, and confirm current rates and tax rules with your bank, fund house or a qualified advisor before committing money.

Professional Financial Investment Calculator एक फ्री, ब्राउज़र-आधारित planning टूल है जो एक साधारण compound-interest calculator से बढ़कर यह मॉडल करने का पूरा इंजन बन गया है कि पैसा कैसे बढ़ता है। इसका मक़सद उन असली सवालों का तेज़ और ईमानदार जवाब देना है जो लोग अपनी savings और investment को लेकर पूछते हैं — यह कितना बनेगा, किसी लक्ष्य तक पहुँचने के लिए मुझे कितना निवेश करना होगा, inflation और tax के बाद इसकी असली कीमत क्या होगी, और एक विकल्प दूसरे से कैसे बेहतर है? यह सब आपके ब्राउज़र में ही होता है, इसलिए आप असली आँकड़ों के साथ बिना कहीं भेजे स्वतंत्र रूप से प्रयोग कर सकते हैं।
इसके केंद्र में एक सावधानी से बना simulation इंजन है। किसी एक बंद-सूत्र (formula) पर निर्भर रहने के बजाय जो सिर्फ lump sum पर फिट बैठता है, यह निवेश को महीने-दर-महीने आगे बढ़ाता है, आपकी चुनी हुई compounding frequency (daily, weekly, monthly, quarterly, half-yearly, annually या continuous) पर growth लगाता है, और आपके नियमित contribution जोड़ता या withdrawal घटाता है ठीक उसी समय जब वे होते हैं। यही period-by-period तरीका एक ही टूल को बहुत अलग-अलग products का सही प्रतिनिधित्व करने देता है — FD बिना contribution वाला lump sum है; RD या SIP समान contributions की धारा है; SWP invested corpus से withdrawals की धारा है; और PPF या NPS सालाना/मासिक contribution है। ऊपर से investment type चुनने पर संबंधित inputs समझदार defaults से भर जाते हैं, पर हर field editable रहती है।
Results जान-बूझकर सिर्फ एक अंतिम आँकड़े से ज़्यादा समृद्ध हैं। मुख्य total investment, interest/wealth gain और final value के साथ टूल आपका ROI, CAGR, effective annual return, और सबसे अहम — inflation-adjusted value तथा post-tax value दिखाता है। Nominal returns भ्रामक हो सकते हैं: भविष्य के रुपयों में प्रभावशाली दिखने वाला corpus inflation के बाद उम्मीद से बहुत कम ख़रीद सकता है, और gains अक्सर taxable होते हैं। असली, ख़र्च-योग्य परिणाम को मुख्य आँकड़े के साथ दिखाकर यह calculator आपको उन्हीं आँकड़ों पर फ़ैसला लेने में मदद करता है जो सच में मायने रखते हैं।
समझना तब आसान होता है जब आप देख सकें, इसलिए इंजन चार chart views देता है — area, line, bar और principal बनाम interest का pie — सभी सीधे HTML5 canvas पर बिना किसी external library के बनते हैं, जिससे पेज तेज़ और पूरी तरह offline-सक्षम रहता है। charts के नीचे एक साल-दर-साल growth table है जो हर साल का invested amount, जमा interest, चालू balance और साल-दर-साल growth प्रतिशत दिखाती है। इस schedule को CSV, Excel, PDF के रूप में export किया जा सकता है या chart को PNG के रूप में सहेजा जा सकता है, और पूरे view को प्रिंट किया जा सकता है।
मुख्य calculator के अलावा चार केंद्रित modes उन सवालों को संभालते हैं जिन्हें सीधा projection हल नहीं कर सकता। Compare दो scenarios को एक ही axes पर रखता है ताकि SIP बनाम lump sum, या अलग rates/compounding की बहस पैसों में सुलझ जाए। Goal planner किसी target से उल्टा काम करता है — बताइए कि 15 साल में एक करोड़ चाहिए और यह ज़रूरी monthly investment, समय या rate निकाल देता है, उसी simulation इंजन पर numerical search से। Reverse calculator lump sum के लिए ज़रूरी principal, rate या time निकालता है। और Inflation mode purchasing power के क्षरण को अलग दिखाता है — present value, future value, real return और "inflation loss"।
यह टूल यह भी मानता है कि पैसा निजी है। सब कुछ client-side चलता है, इसलिए आपके amounts, rates और goals आपके डिवाइस से बाहर नहीं जाते; कोई account नहीं, कोई tracking नहीं। यह सात currencies को सही local formatting के साथ सपोर्ट करता है, आपकी हाल की और सहेजी गई calculations आपके अपने ब्राउज़र में याद रखता है, और inputs को validate करता है। एक ज़रूरी सावधानी हर projection पर लागू होती है: यह एक constant rate of return मानता है, जिसकी असली बाज़ार और FD भी लंबे समय तक गारंटी नहीं देते। outputs को planning और तुलना के लिए एक सूचित अनुमान मानें, और पैसा लगाने से पहले मौजूदा rates तथा tax नियम अपने बैंक, fund house या योग्य सलाहकार से verify करें।
