Monthly budget
See how much of your monthly income remains after living costs. Compare that remainder with the amount you want to save.
Investing and money calculators
First decide whether you are making a budget, estimating future funds or reviewing past investments and repayments.
Which tool fits this question?
Use monthly budgeting for cash remaining and savings targets for regular contributions. CAGR requires no interim cash flows; choose XIRR for irregular contributions. Loan payments use fixed-rate amortization and do not constitute loan approval.
- What remains after monthly living expenses?
- How much should I save each month to reach my target on time?
- How do I annualize returns with contributions and receipts on different dates?
Enter interest rates, inflation, fees and taxes you can verify. Results are conditional estimates, not asset-allocation advice or guaranteed returns.

Savings target projection
Compare a future savings target with your starting money and monthly contributions. See both nominal money and purchasing power under your assumptions.
Savings goals
Plan monthly saving for one goal or several household goals. Allocate each existing amount to just one goal.
Investment profit and loss
Calculate a completed or hypothetical trade's net gain after entered costs. Enter the actual number of shares or asset units.
Compound annual growth rate
Express a change in investment value as an equivalent compounded annual rate. Use this for a holding without intermediate deposits or withdrawals.
Loan payment and early repayment
Estimate a fixed-rate loan's equal monthly payment. The optional prepayment mode shows how extra principal can shorten the loan term.
Goal completion
Compare how much you have completed with a total target. The two amounts must measure the same thing.
Portfolio rebalancing amounts
Calculate increases and reductions from your own target percentages, current holdings and optional new contribution. No investment mix is recommended.
Ex-dividend reference price
Estimate a theoretical reference price after cash dividends and free bonus shares. Enter the number of shares held rather than stock lots.
Retirement withdrawals and asset duration
Estimate how long assets can cover spending after a fixed income. Compare beginning-of-month and end-of-month withdrawal timing.
Compare debt repayment order
Compare repaying smaller balances first with repaying higher-interest debts first. Enter each debt on a separate line, using amounts in one currency.
Return on dated cash flows
Estimate an annualized return when investment and recovery dates are irregular. Enter money invested as negative and money received as positive.
