Money-over-time arithmetic: compound interest, amortisation schedules, APR, annuities, break-even points and investment returns. Each page states the compounding frequency and fee assumption it applies, because those two choices move the result more than any other input. Figures are illustrations for general information, not financial or tax advice — confirm anything you will act on with a qualified adviser.

Separate cash-flow tools (compound interest, loans, hourly-to-salary) from one-step percent-of-money tools (discount, tip). Compounding frequency and deposit timing change totals more than most rate tweaks; each page shows the convention it chose.
Compare borrowing and housing costs
Use the mortgage tool for a home-loan payment with ownership costs, loan comparison for competing offers, and amortization for the balance over time. For renting versus buying, choose between a cash-cost comparison and a net-worth scenario that includes investing the difference.
Separate income, contributions and growth
Convert hourly wages to gross annual pay or reverse that calculation from a salary. For savings, distinguish money you contribute from interest earned. A compound-interest scenario assumes the entered rate; the inflation tool answers a separate question about purchasing power.
Make a like-for-like comparison
Match repayment terms, payment frequency and the timing of deposits before comparing results. Fees, taxes, rate changes and product terms can alter a real outcome. These tools apply stated assumptions; they do not determine loan approval or promise an investment return.
