About each calculator
Meeting cost calculator
The meeting cost calculator dey turn that calendar block wey look abstract to real dollar figure. Enter number of people wey attend and average annual salary, and the counter go start when you click start — e go show exactly wetin that time dey cost as e dey pass. The calculation use simple hourly rate model: annual salary divide by 2,080 working hours, multiply by attendees and elapsed time. You fit pause and reset any time.
This tool dey most useful to raise awareness about meeting culture for an organisation. A 45‑minute standup with 12 engineers at $120,000 per year dey cost over $400 each time. A weekly sync for that cost go add up pass $20,000 for one year. As you dey see the number dey tick up for real time, e go make the cost concrete in a way wey spreadsheet estimate no fit do.
Freelancer hourly rate calculator
The freelancer rate calculator dey work backwards from wetin you need to earn. Enter your target annual income, annual business expenses, billable hours per week, and effective tax rate — the calculator go output the minimum hourly rate wey you must charge to cover everything and still carry your target go house. E account for the reality say freelancers no dey bill 40 hours per week: some hours go enter admin, sales, invoicing, and downtime between contracts.
Many freelancers dey underprice because dem dey compare their hourly rate to salaried colleague wage and forget say dem pay their own taxes, health insurance, equipment, software, and retirement contributions. A freelancer wey dey earn $80/hour fit take home less than employee at $55/hour once you include all costs. This calculator make that comparison clear so you fit set rate wey actually work.
Loan payoff calculator with extra payments
The loan payoff calculator go show your standard amortisation schedule and then calculate am again with any extra monthly payment wey you choose. E display the new payoff date, the total interest saved, and the number of months wey cut from the loan term. E work for any fixed‑rate loan — mortgage, car loan, student loan, or personal loan. You fit try different extra payment amounts and immediately see how each one change the outcome.
The mathematics of extra payments no be intuitive: extra $200 per month on a 30‑year mortgage at 7% no go reduce the term with any neat fraction — e fit cut 5 or more years off the loan and save tens of thousands in interest, because each early payment reduce the principal wey future interest dey charge.
FIRE number calculator
The FIRE number calculator dey estimate how much you need save before you fit retire, based on your expected annual spending and a chosen safe withdrawal rate. The standard approach use the 4% rule derived from the Trinity Study: a portfolio invested in a mix of stocks and bonds don historically sustain a 4% annual withdrawal long‑term. Your FIRE number na 25 times your annual expenses.
The 4% rule na rule of thumb, no be guarantee. Some FIRE people dey use 3% or 3.5% withdrawal rate for early retirement, which raise the target to 33x or 28x expenses respectively. The calculator let you adjust the withdrawal rate so you fit compare targets under different assumptions.
US CPI inflation calculator
The inflation calculator dey convert a dollar amount from one year to the equivalent for another year using the US Bureau of Labor Statistics Consumer Price Index (CPI). Enter a dollar amount, a starting year, and an ending year — the calculator go return the equivalent value adjusted for cumulative inflation or deflation.
CPI dey measure price changes across a fixed basket of consumer goods and services, so na the standard reference for measuring purchasing power changes over time. Common uses include understanding how much salaries don change for real terms, comparing historical prices to today, and calculating real returns on investments.
Which calculator to use
For most financial questions, pick the tool wey match wetin you already know. Wondering whether a meeting worth everybody time? Use the meeting cost calculator and start the timer. Setting a freelance rate? Enter your expenses and income target in the freelancer rate calculator. Trying to pay off debt faster? The loan payoff calculator show exactly how much interest extra payments go save.
For longer‑term questions, the FIRE number and inflation calculators work well together. Use the FIRE calculator to set a savings target based on today spending, then use the inflation calculator to understand how much that spending fit rise for real terms by the time you retire.
How to use these calculators well
Every finance calculator depend on assumptions. A meeting cost estimate depend on average salary and whether benefits or overhead dey included. A freelancer rate depend on realistic billable hours, taxes, and downtime. A loan payoff projection assume a fixed rate and say extra payments na actually applied to principal. A FIRE estimate depend heavily on future spending and a withdrawal rate wey fit — or fit no — match your retirement horizon.
That no mean the tools no useful; e mean the best way to use them na comparatively. Try a conservative case, a likely case, and an aggressive case. If the answer stay roughly the same across all three, you probably understand the range well enough to make a decision.
