Please wait a moment. Your account data has not been changed.
Build personal budgets, plan business cash flow, explore compound growth and estimate UK salary deductions with clear assumptions.
Enter roughly what comes in and what normally goes out each month. You do not need perfect numbers for this to be useful.
After the spending you entered, you currently have around £350 left each month. That does not mean you need to invest it or even save all of it. It simply shows the part of your income that is not currently committed.
Save a 12-month operating plan, compare recorded actuals, test scenarios and keep a portable copy of your data.
Figures are private to your account and are not shown to organisation managers.
Important: this is a management budgeting and cash-planning tool, not bookkeeping, payroll, bank reconciliation, statutory accounts or a tax return. VAT and tax reserves are planning assumptions; confirm treatment and filing obligations with a qualified accountant.
These calculator figures stay in your browser and are not saved. Only the signed-in business workspace above is stored.
Explore how a starting amount and regular monthly contributions could grow when returns are reinvested.
Assumes contributions are made at the end of each month and a constant return compounded monthly. Real returns vary, investments can fall, fees and tax are excluded, and this is not a forecast or financial advice.
Estimate Income Tax and standard employee National Insurance from an annual salary. Scotland uses its separate earned-income bands.
Estimate for an employee with a standard category A National Insurance position and salary as their only taxable income. It applies the Personal Allowance taper above £100,000.
It excludes pension contributions, benefits, tax-code adjustments, student loans, dividends, savings, self-employment and Marriage Allowance. NI is annualised, so payroll rounding may differ.
Rates checked 14 September 2026 against HMRC rates and thresholds and Scottish Income Tax bands. This educational estimate is not tax advice; use HMRC or a qualified adviser for a personal calculation.
Explore realistic scenarios without creating an account. Figures stay in this browser session and are not sent to Morrow or included in organisation reporting.
Turn loan instalments, wages and upfront costs into a realistic allowance for the months you need to cover.
Do not enter a tuition-fee loan as spendable income: it is normally paid directly to the university. This browser-only planner is educational and does not save or share these figures.
Estimate the deduction from earnings—not how quickly the full balance will disappear.
Plan 1 includes borrowers funded by Student Finance Northern Ireland. Your plan normally depends on who funded you and when your course began.
Annual illustration only: payroll calculates each pay period, bonuses can change a deduction and thresholds can change. Balance, interest and write-off are deliberately excluded because they do not determine the standard payroll deduction.
Rates checked 27 September 2026 against HMRC plan thresholds and Student Finance NI. Verify your plan in your official account.
See how payment size, APR and fees change the time and total cost of clearing a balance.
Assumes a constant APR, no new spending and one payment each month. Actual minimum-payment formulas, promotional periods, daily interest and late fees vary. A 0% BNPL plan can still charge late fees or cause harm if payments are missed. This is not debt advice.
Estimate annual and monthly pay from shifts, then see the main deductions that may appear on a payslip.
Look for gross pay, hours or units, tax code, Income Tax, National Insurance, pension and net pay on a real payslip. Keep it and query unfamiliar deductions promptly.
This smooths irregular shifts across 12 months. Payroll works by pay period, and pension tax relief, tax codes, holiday pay, tips, benefits, multiple jobs and employer pension contributions can change the result. It is an educational estimate, not tax advice.
Learn what an emergency fund is and why having some cash available can make unexpected costs less painful.
Turn something you want, from a holiday to a house deposit, into a realistic monthly savings target.
Once your short-term finances make sense, learn how long-term investing works before deciding whether it is right for you.
