Loan Payment

Calculate payment amount, total interest, payoff timing, and the effect of extra payments on a fixed-rate loan. Compare two loan scenarios side by side.

Estimate when your portfolio could cover your living costs. Choose either a safe withdrawal approach or a dividend-income-only target, then track FI age, coast FI, and progress toward an inflation-adjusted goal.

Compound Interest

Estimate how your money can grow over time with compounding, recurring contributions, optional tax drag, and side-by-side scenarios. Set principal, return, horizon, and compounding frequency to see projected future value.

Savings Plan

Project the value of regular savings contributions with a fixed expected return. Set your starting balance, contribution schedule, annual return, time horizon, and optional yearly contribution increases.

Inflation Impact

See how inflation can raise future costs and reduce purchasing power, then compare how investing may help preserve real value. You can model multiple expense lines side by side.

Rent vs Buy

Compare renting and buying by projected net worth at your chosen horizon. Model mortgage costs, maintenance, taxes, rent growth, and how invested unused cash may compound.
