About Rechenweg Finanzmathe
Rechenweg Finanzmathe is your finance calculator and exam trainer for investment appraisal, financial mathematics and cost and financial accounting in business studies. NPV, IRR, annuity, payback period, present and future value, bond yield, WACC, CAPM or contribution margin: the app shows the complete step by step solution for every problem in exam format, with formula, values inserted, intermediate results and result. It is free for the example of every method and with Pro for your own numbers.
THE ELEVEN MODULES
• Time value of money: compounding, discounting, annuities, intra-year and continuous compounding, term, effective rate and real interest rate
• Investment appraisal: net present value, internal rate of return, annuity, payback, static methods, Baldwin, taxes and leasing versus buying
• Bonds: price, effective yield, accrued interest, clean and dirty price, spot rates, forward rates and callable bonds
• Decisions under uncertainty: decision rules, mean-variance rule, decision tree and sensitivity analysis
• Dean model: optimal investment program and diversification
• Portfolio and capital market: return, risk, portfolios, Sharpe ratio, capital market line, beta and CAPM
• Company valuation: capitalised earnings, dividend models, multiples, WACC, EVA and DCF
• Financing: repayment schedule, effective rate with discount, cash discount, foreign currency loan, capital increase and leverage
• Key ratios: balance sheet analysis, liquidity, profitability, ROCE, cash flow statement and financial plan
• Cost accounting: cost theory, cost allocation sheet, job and process costing, profit statement, standard costs and variances, contribution margin, target costing and activity-based costing
• Financial accounting: bookkeeping, year-end closing, VAT, cost of goods used, depreciation, deferrals, accruals and IFRS
Every calculation comes with a chart, such as the NPV profile, the yield curve or the variance waterfall.
PRACTISE AND LEARN
The trainer starts with worked examples, hides steps one by one and finally lets you calculate on your own. In chart tasks you choose the right chart and assess it. A true-or-false trainer checks your understanding with the reason, and the practice exam can follow the layout of a real exam. Hints help in levels, and typical mistakes are named instead of just marked wrong. The app spaces repetitions with FSRS, and the study plan spreads the material backwards from your exam date. Your progress shows what you have covered and how well you know it. If you like, the solution path also shows the key sequence for your calculator. An optional study reminder (at most one a day) keeps you on track.
FREE AND PRO
Free: every calculator with result and formula, one worked example per method with the complete solution path, the trainer's model solutions and the progress overview.
Pro: complete solution path for your own numbers, trainer levels 2 to 4 with generated problems and error diagnosis, exam mode, repetition with FSRS, daily plan and study plan, exam readiness and export of the solution path as PDF. Pro keeps growing: we keep adding new problems and further modules.
Pro is available as a monthly, a semester (6 months) and a yearly subscription. The monthly subscription starts with a 7 days trial if you have not used it before. The store shows price and term before you buy. The subscription renews automatically unless you cancel at least 24 hours before it ends. You can manage and cancel it any time in the Google Play Store under Subscriptions.
A learning and calculation aid, not financial advice and no guarantee of exam success. No account, no advertising: your learning progress stays on your device.
