Calculator collection

Finance Payment Calculators

Use this cluster to plan retirement targets and contributions, compare compensation and work arrangements, and model investing, saving, rent, payment, payoff, affordability, subscription, insurance, and debt scenarios.

How to use this collection

Use this collection for retirement targets, FIRE timing, Coast FIRE, 401(k) growth, contribution gaps, savings, gross pay, work costs, housing, borrowing, credit, and debt payoff. Start with the calculator that owns the decision instead of blending account growth, target setting, contribution solving, and loan arithmetic.

Buying guidance

For retirement and savings guidance, verify account balances, plan documents, fees, taxes, benefit estimates, contribution limits, and the risk behind any entered return. For borrowing, confirm APR, fees, taxes, insurance, PMI, closing costs, lender terms, and budget room with current quotes or account data.

Common mistakes

Common mistakes include treating a smooth return or withdrawal assumption as guaranteed, comparing future and today's dollars, inferring a 401(k) match, comparing payments without matching terms, and ignoring fees, taxes, insurance, or changing cash flow.

Popular calculators

Start with the tools that match the decision you need to make, then use a related calculator for the next check.

Finance Retirement Calculator Project retirement savings at a selected age and compare the inflation-adjusted result with an income-adjusted spending target. Finance 401(k) Calculator Project a 401(k) balance from current savings and separate fixed monthly employee and employer contributions. Finance FIRE Calculator Calculate a spending-based financial-independence target and the first modeled month fixed contributions reach its inflation-growing value. Finance Coast FIRE Calculator Calculate the invested balance needed today to reach a spending-based future target with no additional contributions.

How to narrow the choice

Choose by the output needed: a selected-age retirement trajectory, account-only 401(k) projection, FIRE crossing month, Coast FIRE balance, required retirement contribution, savings timeline, gross-pay comparison, housing budget, payment, or payoff plan. Keep unlike models and assumptions separate.
