How to Budget, Save, Get Out of Debt, and Take Control of Your Money for Good
Julian R. Sterling
One Excel workbook. It puts figures on the chapter that matters most — getting out of debt
— and ends with a calculator for one debt of your own. It is free.
Nothing is gated behind a sign-up, and no email address is asked for.
Chapter 7 says high-interest debt can trap you in a cycle where you pay and pay yet the
balance barely shrinks. Here is that sentence as a number. On a 3,200 balance at 22.9 per cent,
the month’s interest is 61.07 and the minimum payment is
81.53. So 20.46 reaches the debt and three quarters of the
payment does nothing but stand still.
Nothing about that ratio is a lack of discipline. It is the arithmetic of a minimum set as a
percentage of a balance that interest keeps refilling, and it would do the same to anybody. Pay
only minimums on all five debts in the example and they clear in 258 months —
twenty-one and a half years, repaying 1.78× what was borrowed. Add 250 a month of
surplus and the same debts clear in 30 months. Twenty-one years, or two and a
half.
What the snowball costs. The book says attack the highest rate for efficiency or
the smallest balance for motivation, and pick the one you will stick with — then declines to
say what the choice is worth. It is worth 224 and one extra month: about seven
pounds a month. Which makes the book’s advice right rather than diplomatic. If clearing
whole debts early is what keeps you going, buy the motivation.
And a question worth asking before the argument: on these debts the smallest is the store card,
and the store card is also the most expensive — so both methods attack the same debt first.
Small balances and high rates travel together more often than people expect. The file tells you
whether your two methods actually disagree.
What the emergency fund costs. The book says building a starter fund while still
in debt is wise. It is — but it is not free, and it does not pay for itself. It costs about
347 in extra interest, and roughly the same whether the emergency arrives or not.
That is the premium on an insurance policy, and what it buys is that a surprise does not land on
your most expensive card at the worst moment and end the plan. Most people who fail at debt payoff
fail after a surprise, not because of the rate. “It is wise” asks you to
believe something; “it costs about 350, and here is what that buys” lets you
decide.
The last sheet is a blank calculator for one debt of yours: how much of your payment is interest,
how long it takes at what you pay now, and what adding ten or twenty pounds a month would save.
That last answer is usually far larger than people expect. Thirteen checks.

The one calculation to do tonight
Take your most expensive debt. Multiply the balance by the rate, divide by twelve — that is what
it costs you this month. Subtract that from what you actually pay it. The difference is all that
reaches the debt. If it is small, you now know why progress has felt impossible, and it is not
because of anything you did. If it is negative, the balance is growing while you pay it
— which is the situation to seek reputable local help for rather than grind at alone.
What the arithmetic does not settle
It cannot tell you what help is available where you live, what options exist for someone in serious
difficulty, or whether any particular offer is reputable — and some offers aimed at people in
debt are predatory. It cannot price the relief of clearing a debt, which is real and is most of why
the smallest-first method works for the people it works for. And it assumes you can hold a surplus
steady, which is the hardest part and the one no spreadsheet helps with.

Articles on this book
One of the calculations in this workbook, worked out in full.
All articles.
Closing the DealTwo defensible bridges 20.70 million apart, a peg worth 7.00 million, and the six choices that remove 6.60 of a 12.00 earn-out.
CMBS and CRE CLOsWhere the loss actually lands, from appraisal reduction to realised severity, and what the B-piece is really being paid for.
How to Read a Commercial LeaseThe three refinements chapter 19 names and never performs, and the renewal rate below which the mark-to-market is worth nothing.
How to Read a Credit AgreementWhere the default actually comes from, the cure that costs 5.5 times the other, and the capacity nobody adds up.
How to Read a Real Estate Loan AgreementThe cure ratio in closed form, the four-point window in which the cheap cure works, and the cure sized to the wrong threshold.
Office Real EstateA six per cent yield that returns 3.2 per cent once the re-letting cycle is paid for, and the headline-to-net-effective rent arithmetic.
Private Equity Real EstateBoth worked waterfalls to the dollar, the two capital stacks, and the arithmetic of the promote made changeable.
Private Markets PerformanceThirty-one of the thirty-three figures chapter 19 publishes reproduce exactly — and the two that do not are named rather than quietly adopted.
Raising a Real Estate FundThe chapter 17 funnel run on a calendar — when the first close actually lands, and why more travel does not help.
Real Estate FinanceFour people look at one building and reach four numbers; the lender is whole only above 105,109,489, twelve per cent below today’s value rather than forty.
Real Estate Financial ModelingProperty, development and fund models built line by line, and the modelling test worked end to end.
Real Estate Fund ManagementThe waterfall of 6.11, the build-to-core of 8.7 and the proceeds gap, reproduced as live formulas rather than asserted.
REIT Analysis and ValuationFFO of 532.0, AFFO of 381.0, net asset value and dividend safety — every figure a formula you can change.
Retail Real EstateThe occupancy cost of every unit in a centre, the sixteen per cent of the rent roll no tenant can sustain, and the right-size-convert-or-hold decision priced.
Sale and LeasebackA €179.5 million transaction end to end, with rent cover measured on the entity that actually signs the lease.
Self-Storage Real EstateThe cohort engine behind a 590-unit store, and the rate increase on existing customers priced against the move-outs it causes.
The Fund Finance ProfessionalChapter 8 builds the reported-to-eligible NAV bridge; chapter 9 computes every ratio without it. Two points at every state — and what a subscription line does to the IRR.
The Growth Equity InvestorWhat a pro rata cheque really costs, and the band where defending your ownership loses money.
The Private Credit InvestorThe two coverage ratios are not measured on the same thing: the erosion is 47.7 per cent, not the 28.7 the headline implies.
The Private Equity Fund Controller PlaybookThe book defines IRR, DPI, RVPI and TVPI, tells you to update them at the exit, and prints not one value. Computed: a 1.833× deal inside a fund at 0.892 TVPI.
The Venture Capital AssociateWhat defending a position costs, and how many companies a reserve pool actually defends.
Financial Risk ManagementA fund inside every limit that cannot meet a redemption — and the number that decides it is the one with no currency attached.
Business ValuationThree advisers land 26.8 per cent apart on one company, and the whole gap turns out to be 1.96 points of perpetual growth.
Quantitative FinanceThree models agree to a quarter of one per cent about a number that one unobservable input moves a hundred and three times as much.
Asset ManagementFour people quote four returns for one mandate, all correct and 2.7017 points apart — forty-eight times the manager’s net skill.
Alternative InvestmentsA manager reports 13.29 per cent and the endowment earns 6.26 — both correct, and only a third of the advertised advantage arrives.
Credit AnalysisFour defensible EBITDAs on one borrower give leverage from 3.19x to 6.47x — and the add-back argument is fifty times the covenant headroom.
Venture CapitalOne company out of twenty-eight returns 56.7 per cent of the fund, and half the capital goes in after the decision — at half the return.
Machine Learning for FinanceFive people quote the accuracy of one credit model, all five are right, and the number that decides how much money it makes is none of them.
Commercial Real Estate InvestingThe equity earned 8.6647 per cent and the investor received exactly 8.0000 — the preferred return, and nothing above it.
Mergers and AcquisitionsThe board paper says the deal creates 13,436,667 of value. The arithmetic says it destroys 17,530,855. Nobody is lying.
DerivativesThe treasury report says the hedge cost 1,233,698. That is the interest differential, not a cost.
Treasury ManagementFive cash balances for one company, all correct and 145,600,000 apart — and the revolver that is two-thirds of the liquidity leaves at a revenue fall of 8.4127 per cent.
Financial Planning and AnalysisRevenue 3.0190 per cent above budget and operating profit 16.3209 per cent below it, in the same quarter, with every figure correctly stated.
Energy TradingA position report that is 91.7031 per cent hedged and correctly computed, on a book that is short 2,542,000 MWh — and a margin call of 198,400,000 the next morning.
Construction Cost ControlA contract sum of 26,301,102 became a final account of 29,153,363 on the building that was drawn — and 85.8 per cent of what was lost was knowable on the day it was signed.
Pricing StrategyA list price of 148.00, a pocket price of 112.51, and the nine deductions in between — with what one point of price is actually worth.
