Calculators in this category

Refinance Calculator

Compare your current mortgage against a new rate to see your exact monthly savings, lifetime interest reduction, and break-even month after closing costs.

How it is calculated: Monthly Savings = Current Monthly Payment − New Monthly Payment; Break-even Months = Closing Costs ÷ Monthly Savings

Home Loan Calculator

See your true monthly housing payment including principal, interest, local property taxes, homeowner insurance, and HOA fees.

How it is calculated: Monthly P&I = P × [r(1 + r)^n] ÷ [(1 + r)^n − 1] + (Taxes + Insurance + HOA) ÷ 12

Mortgage Payment Calculator (UK)

Calculate monthly repayments in pounds sterling (£) for UK repayment and interest-only mortgages, including your Loan-to-Value (LTV) ratio.

How it is calculated: Capital Repayment: M = P[r(1+r)^n] ÷ [(1+r)^n − 1]; Interest Only: M = (P × r) ÷ 12

Buy-to-Let Mortgage Calculator

Check monthly interest-only payments, gross and net rental yield, and lender ICR stress-test thresholds before purchasing a rental property.

How it is calculated: Gross Yield = (Annual Rent ÷ Purchase Price) × 100; ICR = (Monthly Rent ÷ Monthly Mortgage Interest) × 100

Payment Calculator

Find your fixed monthly installment and total borrowing cost for personal loans, auto finance, or debt consolidation.

How it is calculated: Monthly Payment = [P × r(1 + r)^n] ÷ [(1 + r)^n − 1]

Interest Rate Calculator

See how regular monthly contributions and compound interest grow your savings balance over 1 to 30 years.

How it is calculated: Future Value = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) − 1) ÷ (r/n)]

Freelancer Day-Rate Calculator

Add your target monthly income to your monthly business expenses, then divide by your billable days per month to get your day rate — and divide that by your hours per day for your hourly rate. This is a planning estimate from your own numbers, not tax or legal advice.

How it is calculated: Day Rate = (Target Monthly Income + Monthly Business Expenses) ÷ Billable Days per Month; Hourly Rate = Day Rate ÷ Hours per Day

Website Project Quote Calculator

Estimate a website project price from page count, selected features, an online shop, and design level, with an itemized breakdown and a low–high price range. This is a planning estimate from typical project scopes, not a binding quote — the final price depends on the exact scope.

How it is calculated: Estimate = $500 base + (Pages × $150) + selected feature add-ons + $900 shop add-on; Custom design adds 40% to the subtotal. Low = Estimate × 0.9; High = Estimate × 1.2.
